Amir Ardeshir DVM, MPVM, PhD

(See also: Gastroenterology/Gut Microbiome, Immunology, Systems Biology, Microbiology/Parasitology)

Dr. Amir Ardeshir is an Associate Scientist at the California National Primate Research Center. His research focus is on the establishment of the gut communities (microbiota) in infancy and their role in programming the immune system in non-human primate models. He is interested in the following questions: What underlying mechanisms affect the establishment of the gut microbiota in infancy? And, how does the early age microbiota modulate the immune systems development?

VM:PMI (See also: Immunology, Microbiology)

The Byrne laboratory focuses primarily on microbiological questions as they apply to clinical veterinary microbiology. Some research areas include:

  1. Evaluation of the marine health by detection of pathogens in marine mammals, their food sources, and the marine environment and appraisal of their connection with terrestrial sources.
  2. Environmental contamination by zoonotic fecal pathogens.
  3. Genotyping of clinical isolates to determine their relatedness
  4. Use of mass spectrometry for isolate and strain identification

Some possible project areas:

1)     Evaluation of marine mammal isolates for virulence factors

Bruno Chomel, PhD, DVM

Zoonoses, Bartonella, wildlife, epidemiology

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

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.

Lisa A. Tell, DVM

Department of Medicine and Epidemiology (See also: Food Animal Medicine/Food Safety, Pharmacology/Toxicology)

Dr. Tell is the Director of the Veterinary Drug Residue Laboratory and serves as the Regional Director for the Minor Use Animal Drug and the Food Animal Avoidance Database Programs. She has been a full-time faculty member of the School of Veterinary Medicine since 1994. Dr. Tell's research interests are veterinary drug pharmacokinetic studies for zoological and food animal species. She has a particular interest in treatment options for fungal diseases in birds.

Research studies in Dr. Tell's laboratory vary from pivotal data studies seeking label claims for minor food animal species (particularly goats) to clinically related pharmacokinetic studies for companion birds. Many of the food animal related studies focus on drug residues and residue avoidance in the interest of protecting public health. Research experience gained from working in Dr. Tell's laboratory varies from the in life phase of the pharmacokinetic study to the good laboratory practice bench-top research activities.

Dr. Tell is also the lead investigator for the UC Davis Hummingbird Health program that investigates diseases in free ranging hummingbirds in California.  This program bands the birds, takes biometric measurements, and evaluates birds for infectious diseases.

Renée Tsolis

Department of Medical Microbiology and Immunology, School of Medicine

(see also: immunology, microbiology)

Dr. Tsolis is a microbiologist studying host-pathogen interactions leading to disease during infection. Her laboratory uses a variety of animal models to study how two groups of zoonotic pathogens, non-typhoidal Salmonella and zoonotic Brucella species, interact with the immune system to cause disease. For non-typhoidal Salmonella species, Dr. Tsolis' group is interested in learning why underlying co-morbidities such as malaria and malnutrition increase the incidence of death from systemic infection in the developing world, and her laboratory has developed mouse models to gain insight into immunomodulatory effects of Vitamin A deficiency and malaria. For Brucella, the laboratory has developed models to understand both chronic infection that this group of organisms causes within the mononuclear phagocyte system and to interrogate placental infections in pregnant animals that lead to abortion in domestic animals. Collaborations with UCD research Dr. Luckhart in the Medical Microbiology department, Dr. McSorley in the Center for Comparative Medicine and Dr. Stephensen in the USDA Western Human Nutrition Research Center have been instrumental in establishing this interdisciplinary research program. The long-term goal of Dr. Tsolis' work is to uncover basic principles of how bacterial pathogens manipulate the immune response to cause disease and ensure their transmission to the next host.
