VM: Pathology, Microbiology and Immunology

Mosquito-borne diseases, Epidemiology, Surveillance

My program focuses on the epidemiology and ecology of mosquito-borne diseases, primarily those caused by West Nile, chikungunya, and dengue viruses, and including other livestock diseases such as Rift Valley fever and bluetongue. My research combines laboratory studies and epidemiological methods to understand the environmental drivers of disease outbreaks, and I manage the UC Davis component of the statewide surveillance program for mosquito-borne viruses.

STAR project opportunities in my lab include [1] development of laboratory assays to monitor feeding by individual mosquitoes over time (methods: MALDI-TOF, mosquito rearing and handling) , [2] experiments to define the relationship between temperature and incubation of chikungunya virus in mosquitoes (methods: RT-PCR, MALDI-TOF, mosquito rearing and handling), or [3] analysis of the relationship between West Nile virus risk and drought in California (methods: epidemiology, GIS, basic statistics).

Bruno Chomel, PhD, DVM

Zoonoses, Bartonella, wildlife, epidemiology

VM: Population Health & Reproduction (see also: wildlife)

Dr. Chomel is a veterinary epidemiologist whose research is focused on the epidemiology of zoonotic diseases, especially Zoonoses transmitted by bites and scratches. Most of Dr. Chomel's recent work has focused on cat scratch disease in its feline reservoir and has expanded to wildlife infection by Bartonella as a potential source of animal and human infection.
Research is presently conducted on molecular epidemiology of feline and canine Bartonella, and more recently in bats and ruminants (deer and cattle). Dr. Chomel's laboratory is also interested in the vectors of Bartonella, including fleas, ticks and biting flies. Development of diagnostic tools for cat infection and potential vaccines for cat protection to prevent human infection are also conducted in his laboratory.
His group is also doing wildlife serological surveys for zoonotic infections, including grizzly bears from Alaska , black bears from Western USA ( California , Oregon , Washington ), polar bears and more recently wild carnivores (foxes, raccoons, gray foxes) from various parts in the world. His work also involves the epidemiology of rabies virus. Dr. Chomel maintains important linkage with the Pasteur Institute in Paris, the Lyon and Alfort's Veterinary Schools.

Philip Kass

VM: Population Health & Reproduction

My research falls in the realm of companion animal epidemiology: the study of causes of health and disease in populations of dogs and cats. The studies that I do are non-experimental (or observational), and generally (but not always) do not involve in handling animals and do not involve laboratory work. Examples of STAR projects that I have been involved with in the past include studying factors affecting survival in dogs and cats that underwent cardiopulmonary resuscitation, factors affecting survival in dogs with peripheral nerve sheath tumors, predisposing factors to secondary glaucoma in dogs, determinants of patient outcome in cases of aortic thromboembolism, prognostic factors for recovery of function following intervertebral disk protrusion in Dachshunds, evaluation of national trends in the submission of biopsies of suspected vaccine-associated sarcomas, and owner perception of the effectiveness of nutritional treatment of feline hyperthyroidism. These kinds of studies often begin with ideas formulated by students, and we figure out a way to study them in the time allotted for the STAR program.  I am currently trying to obtain funding to conduct epidemiologic studies into novel statistical approaches to studying possible adverse effects of vaccination on chronic diseases in companion animals.

VM: Medicine & Epidemiology

Dr. Beatriz Martínez López (DVM, MPVM, PhD) is Assistant Professor in the Department of Medicine and Epidemiology, Agricultural Experiment Station (20%) faculty and Director of the UC Davis Center for Animal Disease Modeling and Surveillance (CADMS). Her research is focused on the development and implementation of novel epidemiological methods to gain knowledge about the evolution, spread and economic impact of infectious diseases and to support policies. She uses risk assessment, spatial epidemiology methods, molecular epidemiology, modeling or social network analysis to identify individuals, areas and time periods at higher risk of becoming infected and to detect the most important factors contributing to such risk. She is also working in the integration of these and other methods (i.e. data mining, time-series analysis) in operational, web-based, platforms (i.e., Disease BioPortal, http://bioportal.ucdavis.edu/) with the aim to provide a near real-time monitoring and early warning systems for better prevention and control of transboundary, emerging and re-emerging infectious diseases at a global and local scale. She has been working with diseases affecting domestic and/or wild animal populations such as foot-and-mouth disease, African swine fever, classical swine fever, bovine tuberculosis, Aujeszky´s disease, African horse sickness, bluetongue, avian influenza, West Nile, Rift Valley Fever and diseases affecting aquatic organisms. Many of those diseases are considered to be emerging or re-emerging due to globalization, climate, land use and management changes. CADMS provides a coordinated, interdisciplinary, dynamic environment to develop methods, models and surveillance systems to better prevent, control and eradicate infectious diseases. Currently, CADMS, which accounts with approximately 16 personnel including faculty, analysts, programmers, veterinarians, administrative staff and graduate students, is a FAO Reference Center for modeling and epidemiology and offers diverse opportunities for collaborations in research activities both locally and internationally.

(See also: Food Animal Medicine/Food Safety, Microbiology/Parasitology, Genetics/Genomics)

Dr. Pereira research focuses on evidence based medicine on antimicrobial resistance in livestock and judicious use of antimicrobials through interventions that promote livestock health and well-being. Maintaining the effectiveness of antimicrobial drugs to treat infections is of relevance to the health of both animal and human populations. Recent project investigated enteric microbiota of calves using metagenomic sequencing approaches, and herd management impacts on prevalence of resistant enteric bacteria, including evaluation of drug use, feeding practices, and housing management of dairy calves and heifers.

Epidemiology is the foundation of his research which also employs statistics, microbiology, and molecular and genomic approaches. Using these tools, some current research projects include investigating and identifying risk factors for selection and spread of antimicrobial resistance in Salmonella from livestock, and investigating impacts on drug resistance and animal health from feeding pre-weaned calves waste milk (milk containing drug residues) with the aim of identifying interventions to reduce unwanted impacts from this practice.

Previous projects accomplished include:
Spatial-temporal trends in antimicrobial resistant Salmonella isolates recovered from Northern California dairy cattle at a veterinary microbiology laboratory between 2002 and 2017.

Potential 10 week projects for Summer 2017:
Antimicrobial resistance in bacteria causing metritis in dairy cows.

Evaluation of on-farm factors affecting antimicrobial drug on the dairy farms.
