what is a zoonosis
Protecting yourself and your pets. 1  According to the 26th edition of Dorland's Illustrated Medical Dictionary, Zoonosis is a disease of animals that may be transmitted to man under natural conditions (e.g., brucellosis, rabies).. As doctors who work with both animals and their human owners, veterinarians are an important source of information for zoonotic diseases. When a veterinarian sees or suspects a zoonotic disease, it is the responsibility of the veterinarian to alert the owner of the potential for disease spread to humans.
