Patty Pesavento received her BA at Swarthmore, and her PhD from Harvard University. She received her DVM from UC Davis in 2000, and completed a pathology residency at UC D ​avis in 2003. Residency training included two years in diagnostic research at the California Animal Health and Food Safety Laboratories. She has been on faculty with the Department of Pathology, Microbiology, and Immunology, at the School of Veterinary Medicine at UC Davis since 2005. Dr. Pesavento’s research interests have been principally the identification and characterization of infectious diseases that arise from intensively housed animals or animals at the human:animal interface.


The Pesavento laboratory analyzes novel patterns of disease from the field, including clinically enigmatic diseases from animal shelters. We are interested in emerging pathogens, and/or evolutionary changes in infectious pathogens that arise in the unique shelter environment. We have a collaborative record of viral discovery that includes identification and characterization of virulent feline caliciviruses, canine diarrhea-associated viruses including Amdo-, Kobu, Sappo, and circoviruses, a bovine Astrovirus associated with encephalitis, canine papillomaviruses, and viruses associated with tumors (polyomavirus). The organizing focus of work is to investigate the biology of interactions between viruses and their target tissues. Depending on the virus this work ranges from estimation of causality, development of viral constructs, or tissue culture models of virus:host cell interaction.
