Pathobiology encompasses a diverse complement of disciplines to elucidate mechanisms of host-pathogen interactions. Research leads to tools for detection, control, and prevention of infectious diseases in humans and animals.

The Department of Pathobiology addresses complex problems in biomedical and veterinary infectious diseases.

Emphasis is placed on studies of microbiology, immunology, and epidemiology, with the goals of making healthy humans and animals, along with a healthy environment.

In the veterinary professional degree program, the department teaches courses in both the basic science and clinical portions of the second-year curriculum.

The department is the home to the Pathobiology Graduate Program.
