  • Our first presentation,

  • One Health in Veterinary Education Advancing Career

  • Opportunities that Address Societal Needs will be given

  • by Dr. Michael Lairmore.

  • Please begin when you're ready.

  • >> Thank you, and I'd like to thank all of those

  • at the National Center for Emerging and Zoonotic Diseases

  • and One Health Office for this opportunity

  • to present One Health in educational opportunities.

  • I would like to begin by emphasizing the concept

  • of One Health as an approach which intersects animals,

  • people, and the environment, and this approach requires.

  • This approach requires the interaction across disciplines,

  • ranging from veterinary medicine, public health

  • to engineering and ecology and a cooperative spirit and knowledge

  • and skills to appreciate how multiple disciplines view a

  • societal issue.

  • Viewed from the perspective of the AVMA and AVMC Council

  • of Education which accredits veterinary colleges and schools

  • in the US, we can see elements of the One Health

  • within the curriculum standards, and these include an emphasis

  • on central biological principles,

  • understanding the natural history of disease

  • and principles of the relationship of animals

  • and the environment, including public health.

  • Studies such as the National Research Council's report

  • on the workforce needs

  • in veterinary medicine were published in 2013,

  • have identified the value of the One Health approach

  • to address complex global problems including

  • food security.

  • We also know from the NIH Physician-Scientists Workforce

  • Working Group report of 2014

  • that veterinary sciences are considered a unique workforce

  • in biomedical research

  • and in understanding the emerging epidemics,

  • but are a relatively small workforce in the overall field.

  • The Association of American Veterinary Medical Colleges

  • works to engage member institutions and faculty

  • in the One Health initiatives underway in federal

  • and international agencies, including the NIH,

  • World Health Organization, CDC, and others.

  • This includes sponsorship of the consortium of the university

  • as a global health, which has developed an interest group

  • on global environmental health and One Health and will be part

  • of the 2020 meeting focused on global health at a time

  • of worldwide political change.

  • Viewed from the global perspective, we find the need

  • for One Health approach at the interface of animals,

  • livestock, and wildlife health.

  • This intersection often involves increased contact

  • between humans, livestock, and wildlife, as well as cycles

  • of factors that influence outcomes related

  • to disease transmission, such as economic pressures and land use.

  • The United Nations' sustainable goals include many One Health

  • indicators of the ability of food systems to withstand shock,

  • whether natural or manmade as part

  • of the sustainable global food security and the need

  • for government policies to preserve the environment

  • and natural resources and sustain ecosystems.

  • At UC Davis, we found in bringing real world examples

  • of the One Health approach

  • into the classroom is a compelling way

  • to educate students.

  • These include examples from international projects

  • such as the Health for Animals and Livelihood Improvement,

  • the HALI Project,

  • a collaborative One Health based program in Tanzania

  • and the Gorilla Doctors Program based in Rwanda.

  • Inspired by these case studies and using pilot courses,

  • we've created a new undergraduate major called

  • Global Disease Biology in collaboration

  • with our colleagues at the UC Davis College of Agriculture

  • and Environmental Sciences.

  • This major, which is one of the fastest growing on campus,

  • allows students to study disease and its relationship

  • to the health of people, animals, and plants,

  • as well as the environment in a global context

  • and uses an interdisciplinary approach

  • to advance the understanding of diseases, societal impact,

  • as well as the evolution of prevention of disease.

  • We've also started supported important extracurricular

  • experiences for our students, including participation

  • in the Veterinary Students Day at the Centers

  • for Disease Control and Prevention.

  • We've also found that One Health approach excites our students

  • to work in underserved communities.

  • These communities include Knights Landing, California,

  • which is an economically underserved community

  • with a large migrant population.

  • The goal of the project is to improve health

  • at the community level.

  • This can be extended to One Health experiences globally,

  • which is sponsored by our Office of Global Programs

  • and supports students to work across discipline boundaries

  • and the interconnectedness of humans and animals,

  • but in this context, globally,

  • to provide community-based services.

  • One of the projects is RX for One Health, which provides a

  • "prescription" for advanced students

  • and early career professionals to prepare them

  • for immediate engagement in global health careers

  • that will demand the effective problem-solving skills

  • in a cross disciplinary manner and solid foundations

  • in field and laboratory work.

  • In Tanzania and Nepal, a recent poultry project showed the

  • important role of veterinarians

  • and extension agents in their communities.

  • They found that school children collecting data

  • on household poultry production produced a more accurate result

  • than research staff visiting the households.

  • At UC Davis, the One Health Institute has been integral

  • in global surveillance of zoonotic diseases

  • and capacity building through its leadership

  • of the PREDICT program, a project aimed to define

  • and find viruses before they spill over into humans.

  • Last year, the PREDICT Project announced the discoveries

  • of new viruses, a new Ebola virus' closely related cousin

  • Marburg virus in bats in Sierra Leone.

  • Dr. Brian Bird is a recent example

  • of a veterinary scientist trained in One Health

  • that helped lead the CDC Ebola field laboratory

  • in Sierra Leone in 2015.

  • He's now a faculty member at UC Davis,

  • continuing his One Health work.

  • The work from the PREDICT grant form the basis

  • of a new consortium to enhance global health security the

  • university networks and member institutions in Africa

  • and Southeast Asia by developing training programs

  • and using the One Health approach.

  • The education of the One Health Workforce

  • through interdisciplinary research provides clear examples

  • of how this approach serves

  • to address complex health issues at this interface.

  • Dr. Chris Parker and colleagues have developed a CDC funded

  • Center of Excellence

  • that involves multiple universities and agencies.

  • The Pacific Southwest Regional Center of Excellence

  • in Vector-Borne Diseases includes these partners

  • with approaches and surveillance, vector control,

  • genetics, and methodological tools, but importantly also

  • to train public health professionals

  • and other scientists.

  • One Health approaches are used by the Western Institute

  • of Food Safety and Security and Cooperative Extension Research

  • to investigate and identify solutions to complex challenges

  • in agriculture, from food safety and disease surveillance

  • to biotechnology and animal welfare.

  • These field-based examples are then utilized

  • to create food safety educational materials

  • for stakeholders in government agencies, such as the FDA.

  • These programs have assisted in the implementation

  • of the Food Modernization Act

  • and context large food producing systems.

  • These agriculture-based One Health courses support the goals

  • of Homeland Security and national preparedness systems

  • as well and are tailored for people specifically

  • in rural regions of the United States.

  • Across the country,

  • linked through the National Animal Health Laboratory Systems

  • are laboratory systems

  • that utilize the One Health principles to protect the health

  • of our nation's food supply.

  • A recent example was the effort in California with the USDA

  • to detect and form an eradication program

  • against exotic Newcastle disease.

  • Antimicrobial resistance, as you'll hear about,

  • is a major threat to the health of the world's population

  • and future economies in many countries.

  • A collaborative project co-sponsored by the AAVMC

  • and the Association of Public and Land-grant Universities,

  • APLU, helped form the National Institute

  • of Antimicrobial Resistance at Iowa State University.

  • The institute uses a One Health approach to address the problem

  • and will serve as a national resource for coordinating

  • and focusing the efforts of various stakeholders,

  • organizations, and institutions from academia,

  • government, and industry.

  • We must not forget that the One Health educational approaches

  • are equally critical in small scale farming

  • and emerging trends in urban agriculture.

  • These markets have been recognized by the USDA,

  • which is funding One Health approaches

  • to determine disease risk and educational needs

  • for the stakeholders involved.

  • The parallels of naturally occurring diseases

  • between humans and animals provides multiple examples

  • of how One Health approaches are being used to apply to education

  • and research approaches at the interface

  • of human and animal health.

  • The Clinical and Translational Science Award One Health

  • Alliance is a consortium of 15 veterinary schools partnered

  • through the NIH Clinical Translational Science

  • Award Network.

  • It leverages the expertise of physicians, research scientists,

  • veterinarians, and other professionals

  • to accelerate translational research.

  • Recent examples in non-human primate models

  • of inherited retinal disease provide great examples

  • of therapeutic testing grounds for gene replacement.

  • A recent discovery in a genetic mutation

  • across dog breeds that's responsible

  • for chondrodystrophy provided fundamental knowledge

  • of the importance of a retro gene in dwarfism in humans.

  • Another example was the efficacy of multi-mesenchymal stem cells

  • to treat chronic gingivostomatitis in cats,

  • which is similar to human oral lichen planus.

  • We also see examples

  • in hypertrophic cardiomyopathy parallels between the feline

  • and the human in a study designed

  • to look at new therapeutics.

  • Comparative oncology using the One Health principles that led

  • to new discoveries in cancer treatment

  • and also recent examples of proof of mechanism

  • of new inhibitors that highlight the value

  • of the NCI Comparative Oncology Program.

  • These results in clinical trials at multiple institutions,

  • and these One Health approaches to advance the standard of care

  • of veterinary and human medicine

  • through these organized trials has received great attention

  • across the country.

  • These clinical trials have proved a dual benefit

  • of advancing human health with animal health,

  • but also adding data that shortened time

  • for the approval of human drugs.

  • One Health approach is often applied to wildlife conservation

  • in ecosystem health perspectives.

  • A clear example was the elucidation of toxoplasmosis,

  • a major cause of sea otter mortality off the coast

  • of California.

  • Greater attention in the patterns of emergence

  • of wildlife cancer has offered interesting and novel insights

  • into potential unique non-age-related mechanism

  • of carcinogenesis across the country.

  • As we look to the future, One Health approaches will need

  • to be considered how information technology

  • and data science will be used to identify effective ways

  • of machine learning telemedicine

  • and telecommunication in this context.

  • A recent example from Dr. Titus Brown's group used existing data

  • with new tools to more accurately identify trends

  • across datasets.

  • One Health approaches will be needed

  • as we interpret data science in context to animals,

  • environmental, and human health.

  • A clear example in the Center for Animal Disease Modeling

  • and Surveillance provides coordinated multidisciplinary

  • ongoing research efforts to model disease

  • and predict future disease and also the risk

  • of disease entering the US

  • and evaluating alternative strategies for mitigation.

  • Undoubtedly, finally, One Health trained scientists will be drawn

  • to the concept of planetary health

  • that has emerged subsequent to the One Health movement.

  • This newer concept has foundations in One Health

  • and emphasizes the application of interdisciplinary research,

  • knowledge to improve human health with respect

  • to the integrity of natural systems.

  • I'd like to thank you for listening and for your support,

  • all of you listening, and the support of One Health.

  • Thank you.

  • >> Thank you.

  • Our next presentation, Zoonotic Mycobacterium bovis Disease Deer

  • Hunters in Michigan 2002 to 2017 is by Dr. James Sunstrum.

  • Please begin when you're ready.

  • >> Hello and thank you for inviting us

  • to present this interesting topic.

  • This was published in MMWR on September 20th

  • and involves a multidisciplinary group I represent,

  • Michigan Department of Health and Human Services.

  • We've got involvement from the School of Public Health

  • at University of Michigan, from the Michigan Department

  • of Natural Resources, from the USDA,

  • and from a local hospital system in northern Michigan,

  • which diagnosed a recent case

  • of Mycobacterium bovis in a deer hunter.

  • This article in -- it was a brief report in MMWR

  • and generated quite a bit of attention.

  • And the MMWR site lists the metrics with 22,000 views.

  • It also made the front page of the Detroit Free Press related

  • to hunting-related tuberculosis, and the figure in this report,

  • and I'll spend a little bit of time going over it,

  • it starts on the right-hand side with a figure of a human being

  • with pulmonary TB in red.

  • This was the case that was diagnosed two years ago

  • in northeastern Michigan, along the shores of Lake Huron.

  • And this was an older gentleman, 77 years old,

  • who had been a deer hunter for many, many years.

  • He was a little bit immune suppressed, and he was found

  • to have pulmonary tuberculosis,

  • and it surprised the local doctors

  • when it turned it was identified as Mycobacterium bovis.

  • This was quickly appreciated at the State Health Department,

  • because this patient resided in an endemic area

  • with enzootic Mycobacterium being present

  • in wild deer and cattle.

  • And as a result, his isolate underwent whole genome

  • sequencing, and the purpose of this tree is to show

  • that his isolate was very closely related

  • to an isolate in M. bovis.

  • This is the dark grey circle from 2007,

  • that was a culture obtained from a deer

  • that was analyzed in that same area.

  • And the patient's isolate had only one snip difference

  • from the deer that was recovered many years earlier.

  • Tuberculosis has a very low mutation rate,

  • and this suggests the patient was exposed

  • to Mycobacterium bovis that was circulating close

  • to that time period.

  • These whole genome sequences

  • in veterinary isolates are all stored at USDA,

  • and they have a library of 900 or 1,000 isolates.

  • And they also show that it was closely linked

  • to the blue circle, which was isolated

  • from a cow in that same region.

  • So, we were very interested in this single human isolate

  • that was closely linked to circulating M. bovis

  • in northern Michigan, and I'll show you a map in a second.

  • What we did then was go back to two archived cultures

  • of Mycobacterium bovis that had been published several

  • years ago.

  • They were identified in deer hunters,

  • and the middle case was another pulmonary case,

  • which dates back to 2002.

  • When we analyzed whole genome sequencing there,

  • there was a one snip difference between five deer in grey

  • in that circle in the middle and also three cattle in blue.

  • And then you can see there's some light grey circles

  • where it spills over into some other dead-end animals,

  • such as coyotes, raccoons, or opossum.

  • So, this was a one snip difference, again,

  • a very tight molecular epidemiological linkage.

  • The third case, which has also been published previously,

  • was a case of cutaneous tuberculosis due to M. bovis

  • on the finger of a deer hunter.

  • In that case, the patient's whole genome sequence had a

  • perfect match, because we could identify exactly

  • which deer he had shot, and that was a perfect molecular match.

  • So, this'll give you some background

  • on this enzootic issue that's going on.

  • This has been going on in northern Michigan.

  • It was diagnosed about 25 years ago,

  • where it was recognized there had been spillover

  • of Mycobacterium bovis from cattle into wild deer.

  • And currently, this photograph is what you would see today

  • at the DNR Wildlife Disease Laboratory in Lansing, Michigan.

  • Every day, several hundred deer heads are being submitted

  • for analysis of their lymph nodes for evidence

  • of Mycobacterium bovis,

  • and there is remarkable veterinary epidemiology

  • in the deer population in northern Michigan,

  • going back 20 years or more.

  • I should mention that many

  • of these deer heads are also being evaluated

  • for chronic wasting disease, which is causing great anxiety,

  • and that's in a different part of Michigan.

  • But so, this lab is a dual purpose laboratory.

  • This is one of the largest negative pressure air rooms

  • in the United States.

  • And this is a picture of the DNR veterinarian Dan O'Brien,

  • who was on our publication,

  • and he's holding a very grossly diseased lung from an animal,

  • from a deer diseased with Mycobacterium bovis.

  • This is unusual to find this much disease.

  • Often, it's confined to cervical lymph nodes,

  • which is the main organ to do surveillance on.

  • And Dan O'Brien has provided this chart going back to 1995,

  • showing that every year there have been culture positive deer

  • specimens obtained, and you can see that if you look at 2018,

  • there were 26 deer that were analyzed

  • with positive lymph node cultures

  • for Mycobacterium bovis.

  • This is out of a huge number of deers analyzed,

  • 35,000 last year, that the number

  • of deer being analyzed has risen considerably, but that's mainly

  • because of the concerns about chronic wasting disease.

  • This season, deer hunting season, has just wrapped up.

  • It's in full force right now, and they've identified seven,

  • I believe, culture positive deer so far on the --

  • and these are all confirmed by acid fast culture.

  • This map is to show you that this is confined

  • to a relatively small area in northern Michigan.

  • The yellow area involves four counties where the bulk

  • of Mycobacterium bovis has been identified in deer.

  • And then the red area is the more concentrated higher

  • intensity area, which is called a deer management unit,

  • where there's been more aggressive interventions,

  • and it's been confined to that that area.

  • There are a few other colored circles elsewhere in the state,

  • where there's been scattered herds with evidence

  • of Mycobacterium bovis unrelated to deer,

  • and those are usually cattle herds that had M. bovis brought

  • in from outside of the state.

  • And so, all the efforts of the Department of Natural Resources

  • and the Department of Agriculture

  • in northern Michigan are focused

  • in this concentrated four county area.

  • It's quite rural.

  • It's heavily forested, where there's a lot of deer,

  • and then there's also a lot of cattle farms mingled in.

  • There's lots of opportunities for interaction

  • between wild deer and cattle.

  • So, this slide shows the zoom in on the four county area.

  • This is showing the location of culture positive deer in red

  • that were identified last year.

  • You can see that almost all of them are

  • within that tighter deer management unit,

  • and that's really where a lot of efforts are being made to try

  • and deal with this situation.

  • Now, the next slide is showing more the interaction of deer

  • with cattle farms, and I will explain this slide,

  • because it's presenting the infected deer

  • as squares or rectangles.

  • So, a culture positive deer would either be a red square

  • or a crosshatch square, and you can see they're scattered

  • across this area.

  • But the purpose of this slide is to show the yellow dots,

  • which identified farms

  • with previously infected cattle herds.

  • So, there's clearly close proximity

  • where deer have been shot with very close proximity

  • to cattle farms, which have been affected by Mycobacterium bovis.

  • There are 120 cattle farms in this four county area,

  • and there's been very intensive efforts to work

  • with cattle producers and with deer hunters in this area.

  • Every year in -- and this is in the State of Michigan.

  • In 2016, this graph shows there were three cattle herds

  • in that area that were found to have evidence

  • of M. bovis infection.

  • You can see that this has been an ongoing issue

  • with continued evidence of spread

  • from wild deer into herds.

  • In this part of the state, there are highway signs with this kind

  • of information where all cattle have to be tagged

  • with an electronic identification device,

  • and they cannot be moved outside of this region,

  • unless they have documentation of a negative bovine TB test.

  • This issue has resulted in Michigan being identified

  • as having a modified accredited zone status for restriction

  • of movement of cattle.

  • And I'm not a big expert on how that's performed,

  • but this has put significant restrictions on movement

  • of cattle in this area.

  • There are quite a few efforts now

  • at enhanced wildlife biosecurity, in other words,

  • restricting the ability of deer to get onto farms either

  • by building better fences,

  • by making sure gates are properly closed,

  • and trying to reduce the interactions of wild deer

  • with cattle in the area.

  • Now, just as our case was being accepted for publication,

  • we received notice from the Health Department

  • in northern Michigan that they had identified a taxidermist

  • with a chronic finger infection.

  • This started about last November or December and had no response

  • to broad spectrum antibiotics.

  • It was a chronic festering finger infection.

  • They did a biopsy of this taxidermist's finger

  • and found granulomas,

  • and Mycobacterium bovis was identified in culture.

  • The isolate is known to be resistant to pyrazinamide,

  • which can be used as an indirect marker for this organism.

  • The patient did have a positive IGRA blood test.

  • We're presently sending this patient's isolate to the USDA

  • in Ames, Iowa for comparison

  • of his isolate's whole genome sequencing

  • with the veterinary library.

  • And those results are still pending, but we suspect

  • that he was inoculated when he was cleaning deer heads

  • with wire brushes.

  • It does not appear that he can recall a specific specimen

  • that looked different or looked diseased.

  • So, we may not have the source for that.

  • These cases have generated a lot of discussion

  • about what could be done next, because there's always concern

  • about ongoing transmission to humans.

  • So far, we've only seen diseased and Mycobacterium bovis disease

  • in deer hunters or people who handled deer carcasses.

  • So, we think that education

  • of hunters is going to be necessary.

  • The DNR does put some education

  • in their hunting brochure every year about Mycobacterium bovis

  • and chronic wasting disease.

  • But I think emphasizing the use of gloves for field dressing

  • of animals would be a very easy thing to do.

  • It is very, very unknown whether airborne protection would be

  • feasible for the tens of thousands or hundreds

  • of thousands of deer hunters who go up to Michigan every fall.

  • But -- so we just say

  • that recommendation remains controversial,

  • but two of our cases were pulmonary cases.

  • We can speculate that those hunters got infected

  • from a brief, intense exposure to aerosols

  • when they were field dressing the carcass out in the woods.

  • We would like to proceed with IGRA blood testing for hunters

  • who submit diseased deer heads, and that's a project

  • that we're actively working on getting going.

  • We would also like to simultaneously be doing IGRA

  • screening of cattle producers, who have affected herds.

  • We feel that this area represents a unique location

  • to study the zoonotic transmission of bovine TB

  • between wild animals

  • and domesticated animals and human beings.

  • This topic is now gaining recognition around the world

  • that global zoonotic tuberculosis is really being

  • recognized, that this was launched

  • at a 2017 tuberculosis conference, saying that control

  • of human TB around the world cannot be accomplished

  • without control of zoonotic tuberculosis.

  • This topic has been very foreign for the TB community at large,

  • but just earlier, a month ago, in Hyderabad, India,

  • there were four major sessions on zoonotic TB working

  • to advance understanding of this topic.

  • Thank you.

  • >> Thank you.

  • Our final presentation,

  • CDC's 2019 Antibiotic Resistance Threats Report is

  • by Michael Craig.

  • Please begin when you're ready.

  • >> Hello all, and thanks for listening, and we're excited

  • to give you an overview of CDC's AR Threats Report.

  • You probably saw some of the releases in the middle

  • of November in the news, and I just want to walk

  • through some of the pieces.

  • I'm happy to give an overview, and it's, in particular,

  • something that's very important to us, because it is

  • such a important One Health issue.

  • And I think the report actually puts some finer points on that

  • in ways that we haven't been able to before, and so thanks

  • for the opportunity to share it with you.

  • So, I want to just highlight that some of the data pieces

  • in the report, importantly,

  • CDC put out the 2013 AR Threats Report,

  • and we used the best data available that we had

  • at the time, but that was really pre-investment

  • from the Congress in this topic.

  • And so, CDC put out our estimate,

  • but we also caveated it pretty significantly

  • when we put it out, and we've talked about it in --

  • with caveats ever since then and ever since we've sort

  • of released our new report.

  • And the big caveat was that we really had conservative

  • estimates, because we didn't have better data to be able

  • to assess the burden for all the different pathogens

  • in the report.

  • And looking at the slides here and just advancing,

  • so you can see this, we used new data this time, and the new data

  • that we used from primarily electronic health record data

  • from three different electronic health record vendors,

  • we pulled that together and really had data from millions

  • of different patients across the spectrum of healthcare.

  • And we're able to really get data specifically,

  • that not only highlighted the current burden of AR Threats

  • in the United States, but also gave us data that went back

  • in time to when we released the first report.

  • And it allowed us to actually recalibrate,

  • re-estimate what the burden of AR was

  • with these better estimates.

  • And as you can see here with this slide,

  • the two million was underestimated, and it was more

  • like 2.6 million infections.

  • And the deaths notably were underestimated pretty

  • significantly, and they went from 23,000 to 44,000,

  • which is an important point, as I note where we are today.

  • These are the numbers, as you can see here, about where we are

  • with the burden of antibiotic resistant infections

  • and the pathogens that we highlight in the report today.

  • Notably, we're at over 2.8 million infections.

  • An important piece though is

  • that the deaths number has actually declined,

  • from 44,000 to just a little below 36,000.

  • And that decline is largely due to success that we've had

  • in preventing resistant infections

  • in hospitals in particular.

  • The data that we had really focused on hospital settings

  • versus community settings,

  • and provided information specifically

  • about the differences there.

  • And so, I would highlight here that the success that we've seen

  • in the declines overall in deaths and mortality,

  • over this period of time from roughly 2012 to 2017,

  • is attributed to a lot of the interventions and things

  • that we have put in place in the United States

  • over the last decade to improve patient safety

  • and health care quality in hospitals.

  • All that being said, it's important to note though,

  • that if you add up the burden of the resistant threats along

  • with the burden of C. diff, which is the companion pathogen

  • that we include in the report, because it's driven

  • by antibiotic use, you get over three million infections

  • and nearly 50,000 deaths, which is a lot of sick people

  • and a lot of deaths that we have to deal

  • with in the United States.

  • And frankly, it's too many, and it's something that we need

  • to do even more about in the United States to address.

  • The report also does categorize pathogens and,

  • compared to the last report, would highlight for you

  • that we have the three categories of urgent, serious,

  • and concerning, and last time, in the highest category

  • of threat, we had three pathogens.

  • And this time we have five pathogens,

  • and as you can see here with the categories,

  • there were two major changes to that urgent category list.

  • And that is that we added a pathogen, Candida auris,

  • which folks, I think, have probably heard about.

  • This is the multidrug resistant fungus

  • that we really didn't know about the last time we put

  • out the threats report, but has since emerged

  • and really circumnavigated the globe

  • and is really wreaking havoc

  • in healthcare facilities especially,

  • where it becomes colonized and where it becomes prevalent.

  • And so, this is one where given its resistance,

  • given the challenges that we face both in the United States

  • with this pathogen, as well as overseas,

  • and given how readily it's been transmitted and really moved

  • across the globe, we put it and added it

  • to this highest category.

  • We also added Acinetobacter to the urgent list,

  • and this is somewhat of a slight definition change.

  • In the last report,

  • we had multidrug resistant Acinetobacter.

  • This time we changed it

  • to carbapenem-resistant Acinetobacter

  • because of specific concerns we've been seeing to --

  • specific concerns

  • to the resistance we're seeing to carbapenems.

  • And when we looked at that, and when we redefined it

  • and evaluated and compared it to those other urgent threats,

  • we saw that it was warranted to be in that higher category.

  • I would note for you that even though we added Candida auris,

  • the 2013 report and the 2019 report have the same number

  • of pathogens, 18.

  • As we categorized, we actually removed VRSA and combined it

  • with MRSA, given the low prevalence of that

  • and given the relationship between the two.

  • One thing we note with the threats report,

  • and I think it's particularly important to this group is

  • that we spend a lot of time and a lot of hard work with folks

  • across the agency, trying to come up with new infographics

  • that talk about the different aspects

  • of antibiotic resistance and, in particular,

  • talk about the challenges, the One Health challenges

  • of antibiotic resistance and do so in a way

  • that is more accessible to a variety of audiences.

  • This infographic is emblematic of that, and you can see this

  • in greater detail in some of our online material

  • or in the print version.

  • And it -- we really --

  • you really can't zoom in on different aspects of this to try

  • and understand some of the relationships.

  • So, we really, you know, had twin goals

  • of conveying a high level scientific information,

  • but packaging it in a way

  • where multiple audiences could understand the One Health nature

  • of antibiotic resistance and how it touches on really any

  • and every aspect of human life.

  • And this is one, in particular, that we're proud of,

  • because we can zoom in on some of these different parts

  • and highlight the aspects that relate to human healthcare

  • that relate to agriculture in the farm, the use of antibiotics

  • as pesticides, but can also relate to what we deal

  • with in our homes and in our communities day in and day out.

  • So, there's a lot of new infographics.

  • There's a lot of new resources both for healthcare providers

  • with note that we worked with the One Health Office as well

  • as our partners at AVMA to have a sheet

  • on what veterinarians can do to address antibiotic resistance.

  • For a long time, we've had companion materials

  • on the human health side about what doctors

  • and healthcare providers can do.

  • But the report this time launched some other new elements

  • like our fact sheet on what veterinarians can do.

  • And we're proud to sort of bring that approach

  • and improve upon how we message and how we talk

  • about antibiotic resistance as a One Health threat.

  • I would highlight here, these are some

  • of the more specific data that I noted at the beginning

  • about the success that we've seen

  • in preventing resistant infections, as well as driving

  • down the number of deaths.

  • And this has been the success that's really related

  • to the hospital prevention and the hospital successes.

  • And so, you can see some

  • of the most prominent resistant infections in the report,

  • we have seen decreases over this period

  • of time, from 2012 to 2017.

  • And for things like CRE, we have them on this as a success,

  • because we do consider having a stable level of CRE,

  • given it is an urgent threat and given

  • that we have seen it spread in other countries,

  • significantly maintaining that at the level that we're at,

  • when we sort of expected that it would grow,

  • we consider that a public health success.

  • And I think it shows the emblematic of the success

  • that we've had in implementing things

  • like the containment approach and our support to state

  • and local health departments in identifying these emerging forms

  • of resistance and responding to them in real time.

  • I want to highlight though that this is not just a

  • "mission accomplished," but there's a lot more to do,

  • and the challenges that we see, and the challenges

  • that we highlighted in the report, of course,

  • are that the numbers are much bigger

  • than we previously estimated.

  • The other issues are, of course, though, that outside

  • of hospitals, we're not seeing the same level of success.

  • And when we defined community here,

  • we defined healthcare facilities,

  • that non-hospital healthcare facilities

  • in that community bucket as well as true community.

  • So, in those -- both of those areas

  • in the non-hospital healthcare settings, like nursing homes,

  • ambulatory surgery centers, dialysis settings,

  • we're not seeing the same level of prevention

  • of infections and deaths.

  • And we need to really make sure that the gains that we've had

  • in hospitals are maintained and that we carry those successes

  • over to other healthcare settings.

  • Moreover, we're seeing some increases in the true community

  • and for infections that are driven in community settings,

  • like drug resistant gonorrhea, would highlight

  • for you here the ESBL-producing Enterobacteriaceae,

  • in particular.

  • That is one that -- these are largely drug resistant urinary

  • tract infections that disproportionately affect women.

  • This is an area that needs more exploration to see all

  • of the reasons, and we do think

  • that there are multifactorial reasons

  • that are driving these increases up here.

  • But these are serious.

  • These are urinary tract infections

  • that previously would've been treated

  • with an outpatient antibiotic prescription,

  • but because of the resistance issues,

  • folks are unfortunately having

  • to be hospitalized to be treated.

  • And in some cases, if those urinary tract infections proceed

  • to the bloodstream, they can be deadly.

  • I'd also highlight for you, and we do more work in this

  • to highlight the fact

  • that antibiotic resistance is a global phenomenon

  • and a global challenge.

  • While this is a report that is focused on the United States

  • and the threats that we face in the United States, we do note

  • and that this is one of the only pieces of data that we have

  • around the globe about the burden

  • of antibiotic resistance in a country.

  • So, we have good data from the US.

  • We have good data from European countries.

  • Outside of those two spheres, we don't have the same level

  • of data, and we don't have the same level of understanding

  • of the burden of resistance.

  • We don't have a good understanding

  • of the emerging forms of resistance.

  • Sometimes we are identifying emerging forms of resistance

  • for the first time when we see them in the US,

  • even though they may not have originated here.

  • And that's a big challenge for us in a big area, where we feel

  • like there's a lot more that the global community can do

  • and a lot more that CDC can play a role in,

  • in supporting other countries of the world

  • to address those infections.

  • The Threats Report also had a new addition,

  • which was the watch list.

  • The watch list was a little different

  • than the other categories of threats that we had

  • for the other pathogens, in that these three pathogens are ones

  • that we don't have good data on.

  • We don't have data on burden or deaths related to these threats,

  • but there are things that, and in fact, for some of them,

  • they may have extremely low incidence

  • or negligible incidence in the United States.

  • But there are things that we're seeing either in other parts

  • of the world or things that are poorly understood in the US,

  • and we need to have a better understanding of it and move

  • that forward for these pathogens.

  • I want to highlight

  • in particular azole-resistant Aspergillus fumigatus,

  • they're the first one.

  • This is one that we highlighted in the report and note

  • that this is a particular One Health threat and one

  • that we should be aware of.

  • Azoles are one of the main drugs and an important drug

  • for treating fungal diseases.

  • They're also used very widely around the world as a pesticide,

  • and what we're seeing in parts of Europe and the US is

  • that the use of those azoles as a pesticide is creating forms

  • of resistance that are then being inhaled

  • to immune compromised patients in the US and Europe

  • and likely other parts of the world.

  • And they are coming down with these azole-resistant

  • Aspergillus fumigatus infections,

  • and this is something

  • that I think we're paying close attention to and want

  • to learn more about some of the relationships here and figure

  • out how we can minimize these risks and how we can figure

  • out the best way to address these problems that we see

  • in both our plants as well as in people.

  • The report does also highlight the road ahead

  • and highlights the areas that we feel at CDC are where we need

  • to be moving with the our next action plan.

  • Folks may be aware that we are in the final year of the CARB,

  • Combating Antibiotic Resistant Bacteria action plan.

  • It runs from 2015 to 2020, and a new action plan is currently

  • under development across the US Government.

  • These are areas that we, at CDC, feel are critically important,

  • and they're not just the public health areas, but they're things

  • that we feel like need to be done across the spectrum

  • of both public health as well as academics, private industry

  • and greater engagement really from all stakeholders

  • from around the world.

  • Of course, all of this we sort of see

  • through a One Health approach, and we're taking that approach,

  • as we move forward with the new CARB 2.0 action plan,

  • which we hope to be released early next calendar year.

  • And with that, I will stop.
