Avian Medicine & Pathology

poultryAvian Medicine & Pathology has a long history of service to the poultry industry of Pennsylvania, going all the way back to the early career of Dr. Evan L. Stubbs (1920s), when the state diagnostic laboratory was located in Philadelphia.


The mission of Avian Medicine & Pathology is to provide the best possible diagnostic service to Pennsylvania and regional poultry producers, hatcheries, service personnel, feed companies, breeder companies, and veterinarians.

Avian Medicine & Pathology has three distinct missions: Service, Teaching and Research.


Penn Vet’s poultry diagnostic service is recognized as a state and regional resource.  Submissions include birds such as, chickens, turkeys, pigeons, waterfowl, game birds, wild birds and pet birds (e.g., parrots) and surveillance samples (blood and swabs).

The poultry pathologist provides diagnostic information and advice on the treatment, control, and eradication of infectious diseases. Laboratory staff serve on national, state, and regional poultry disease advisory committees.

The staff has also been actively involved in eradication, control, and prevention of avian influenza and in the development and implementation of the Pennsylvania Egg Quality Assurance Program for Salmonella Enteritidis.

Field investigations are conducted to assist producers with an individual farm problem or the industry in control and prevention of new or emerging diseases. Diseases have included avian influenza, Mycoplasma gallisepticum, infectious bronchitis, and Salmonella Enteritidis.


Poultry faculty provide a teaching program for Penn Vet veterinary students, industry personnel, youth organizations, and veterinary technicians. Topics include diagnostic testing, disease prevention and control, food safety, poultry management/biosecurity, and welfare.


Research focuses on control and prevention measures for diseases such as avian influenza, Mycoplasma gallisepticum and Salmonella Enteritidis.
