About

The Wildlife Health Center is an educational, service, and research center within the UC Davis School of Veterinary Medicine. The Wildlife Health Center focuses its efforts on wild animals in the context of their ecosystems, recognizing that without a healthy place to live, wildlife populations and humans will not be able to co-exist. Our goals are to provide wildlife health education for professional and graduate students, to generate objective science towards the specific goal of improving wildlife health, and to promote conservation. The center currently administers 4 targeted ecosystem health programs: Oiled Wildlife Care Network; Marine Ecosystem Health Program; Southern California Ecosystem Health Program; Wildlife and Natural Communities Resource Assessment Program.

Evaluating potential infectious disease threats for southern residentkiller whales, Orcinus orca: a model for endangered species

Infectious diseases have the potential to play a role in the decline of threatened wildlife populations, as well as negatively affect their long-term viability, but determining which infectious agents present risks can be difficult. The southern resident killer whale, Orcinus orca, population is endangered and little is known about infectious diseases in this species. Using available reference literature, we identified 15 infectious agents (bacteria, viruses, and fungi) reported in free-ranging and captive killer whales, as well as 28 additional infectious agents reported in free-ranging and captive odontocete species sympatric to southern resident killer whales. Infectious agents were scored as having a high, medium, or low ability to affect fecundity or reproductive success, to cause disease in individual animals, and to cause epizootics. Marine Brucella spp., cetacean poxvirus, cetacean morbilliviruses, and herpesviruses were identified as high priority pathogens that warrant further study. Using identified pathogens to develop a standardized necropsy and disease testing protocol for southern resident killer whales and sympatric odontocetes will improve future efforts to better understand the impacts of priority and non-priority infectious agents on southern resident killer whales. This model can be used to evaluate potential infectious disease risks in other threatened wildlife populations.
