Any infectious or parasitic disease of animals that can be transmitted to humans. Unlike many disease organisms, zoonotic organisms are flexible and can adapt themselves to many different species.
Zoonoses are usually caught from animals closely associated with humans, either as pets, food sources, or scavenging parasites, such as rats. Examples include toxocariasis, cat-scratch fever, some fungal infections, psittacosis, brucellosis, trichinosis, and leptospirosis. Rabies can infect virtually any mammal, but dog bites are a common cause of human infection worldwide.
Other zoonoses are transmitted from animals less obviously associated with humans, usually by insect vectors. For example, yellow fever is transmitted by mosquito bites. (See also dogs, diseases from; cats, diseases from; rats, diseases from; insects and disease.)
An infection or an infectious disease transmissible under natural conditions from vertebrate animal and humans.
n. an infectious disease of animals that can be transmitted to humans. See anthrax; avian influenza; brucellosis; cat-scratch disease; cowpox; glanders; Q fever; Rift Valley fever; rabies; rat-bite fever; toxoplasmosis; tularaemia; typhus.
A zoonosis. It is an acute, febrile, septicaemic disease caused by the Leptospira interrogans which has more than 200 serovars. The disease is characterised by a broad spectrum of clinical manifestations including fever, chills, headache, conjunctivitis and muscular pains. The disease may be subclinical in mild cases but jaundice and renal failure are observed in severe cases. Includes Weil’s Disease. Can result in an aseptic meningitis.... leptospirosis
An arboviral (flavivirus) disease, also a zoonosis, being essentially a disease of forest monkeys, which under certain conditions can be transmitted to humans. A vaccine is available.... yellow fever
