Wildlife/Exotic Animal Medicine and Zoonoses
Melanie Ammersbach
Department of Pathology, Microbiology and Immunology
(see also: Pathology/Virology, Non-human Primate Medicine)
Dr. Ammersbach is a veterinary clinical pathologist with a special interest in non-traditional species. The areas of expertise of clinical pathologists include clinical chemistry, hematology and cytology. Non-traditional species include exotic pets, zoo animals, wildlife and laboratory animals.
There are many potential projects, including several collaborations with other faculty members, such as: 1. A collaboration with the primate center and Dr. Olstad to evaluate neutrophil morphology with inflammation (retrospective study), and cerebrospinal fluid analysis findings (retrospective and prospective) and their association with a number of diseases. 2. A collaboration with Dr. Van Hoy on a project validating and establishing normal reference intervals for blood gases and coagulation tests in pet minipigs and 3. A collaboration with Dr. Beaufrere documenting lipoproteins in birds (including cockatiels and flamingoes) using high resolution lipoprotein electrophoresis.
STAR students will explore projects in the field of clinical pathology (hematology, biochemistry or cytology) of non-traditional species (exotics, wildlife, laboratory animals).

Krista A. Keller, DVM, Dipl ACZM
VM: Medicine & Epidemiology
(see also: Microbiology/Parasitology)
I am a board-certified specialist in zoological medicine and my research, focused on of mycotic infections of reptiles, allows me (and my mentees) to ask clinically relevant questions to drive hypothesis-based research. I am interested in understanding all aspects of the host-microbe-environmental triad as it relates to infectious disease development to drive meaningful recommendations on the diagnosis and treatment of reptiles infected with mycotic agents.
My mentoring philosophy involves handing students a spark (an idea), then allowing them to light the fire (research and develop a research question) and helping them to appreciate all components of research from ideation, hypothesis creation, methodological planning, material list development, data collection and analysis, through dissemination on the local and national level.
STAR students will study elucidating factors surrounding mycotic infections in reptiles. Students will also be exposed to both project planning and design as well as laboratory based microbiological techniques (culture, pipette, dilutions).
I can be reached at kakell@ucdavis.edu.
Christine Kreuder Johnson, VMD, PhD
One Health Institute
(See also: Global Health, Epidemiology)
Dr. Kreuder Johnson is a Professor of Epidemiology and Ecosystem Health in the School of Veterinary Medicine and Director of the EpiCenter for Disease Dynamics at the One Health Institute at UC Davis. Her research focuses on wildlife population health and the impact of ecological processes on species at risk and patterns of disease transmission in marine and terrestrial wild animal populations. Recent activities investigate zoonotic disease spillover dynamics, viral host shifts, further characterization of the animal-human interface, and epidemiologic patterns facilitating zoonotic disease transmission and spread. She provides epidemiologic support to federal and state agencies during unusual outbreak events and directs global surveillance activities for the Emerging Pandemic Threats PREDICT program.

Benjamin Sacks, Ph.D.
Veterinary Genetics Laboratory, Canid Genetics & Population Health
(See also: Genetics/Genomics)
The Canid Diversity and Conservation Laboratory specializes on ecology and conservation of wild canids and other carnivores, including the application of genetic techniques, disease surveillance, and field methods (see web site below). STAR students will initially learn necessary skills from students, technicians, and faculty, and will spend most of the summer collecting data for their project under faculty supervision.
Dr. Sacks can be reached via email at bnsacks@ucdavis.edu, or you can visit his website for more information.
Karen Shapiro, DVM, MPVM, PhD
VM: Pathology, Microbiology & Immunology
Dr. Shapiro is an infectious disease researcher focusing on transmission of zoonotic pathogens that pose a health risk to wildlife populations and people through water or food. Her research program targets the transport and fate of zoonotic pathogens in watersheds and coastal ecosystems; effects of landscape change and climate variability on disease transmission; impacts of water scarcity and impaired quality on human and animal population health, and food safety. In addition to her research program, Dr. Shapiro also oversees the VMTH parasitology diagnostic laboratory and provides expertise on protozoan pathogens in small, large and exotic animal patients. We have a new project focused on protozoan parasite transmission and ecology from land to sea. The work would involve processing environmental and/or clinical samples for DNA extraction, PCR and sequencing to identify Toxoplasma and Sarcocystis in hosts and environmental matrices.

Dr. Esteban Soto is a board certified veterinary microbiologist who has an interest in aquatic animal health. Our laboratory main research interests are to understand the pathogenesis of important infectious diseases of wild and aquatic animals, and to develop strategies to protect animals from these diseases. Members in our laboratory study One Health, Aquatic Animal Disease, and Fish Disease through a combination of microbiological, molecular, and epidemiological methods. Current projects involve studying the ecology, diversity and host-pathogen interaction of Francisella noatunensis, Piscirickettsia salmonis, Veronaea botryosa, Erysipelothrix rhusiopathiae, Flavobacterium spp., Saprolegnia ferax, Koi herpes virus and other fish pathogens; and studying the ecology, diversity and host-pathogen interaction of hypermucoid Klebsiella pneumoniae in marine mammals.

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.
