The Department of Pathobiology is dedicated to the advancement of knowledge in veterinary and comparative pathology, veterinary infectious diseases and immunology. Our faculty members’ research ranges from the basic understanding of the mechanisms of disease caused by a wide range of agents (including emerging and zoonotic pathogens) to the different protective and pathological responses o host organisms. We offer advanced training in diagnostic anatomic and clinical pathology, as well as research training in our areas of expertise.

Congratulations to Mary Ellen Clark has been awarded the 2016 Carlton L. Gyles OVC Support Staff Excellence Award for outstanding contributions to research and graduate training.

Congratulations to postdoctoral fellow Li Deng (Susta/Bridle labs) and graduate students Jacob van Vloten (Wootton/Bridle labs), Megan Whaley, Robert Mould and Amanda AuYeung (Bridle lab), all of whom have received travel awards to present their research at the Summit for Cancer Immunotherapy in Halifax, Nova Scotia later this month (June 26-29).  Kathy Matuszewska, a graduate student in Dr. Jim Petrik's lab in Biomedical Sciences, also received an award for this conference to present the research that she has been conducting in collaboration with Pathobiology professors Drs. Wootton and Bridle.

Dr. Byram Bridle submitted a manuscript that will be published in the June 1, 2016 issue of the Journal of Immunology. It was selected by the journal to be highlighted in their "In This Issue" section, which features articles considered to be among the top 10% of those published in the journal.  This research has important implications for designing vaccines for diseases requiring rapid, maximal immune responses, including potentially fatal infectious diseases and cancers.

Congratulations to CWHC grad student Jamie Rothenburger (Jardine lab) who was recently awarded a Wildlife Disease Association Scholarship.

Welcome to Dr. Khalil Karimi who has joined the Bridle lab research team as a research associate. Khalil is an immunologist with extensive expertise in innate immunity and cancer immunotherapy.
