Infectious and parasitic diseases of captive carnivores, with special emphasis on the black-footed ferret (Mustela nigripes)

Captive carnivores are susceptible to a wide array of infectious and parasitic diseases, which reflects the diversity of the seven families of Carnivora. Unfortunately, relatively few in-depth studies have been conducted on diseases of non-domestic carnivores, and much remains to be learned, especially regarding diseases of small carnivores (e.g. mustelids, viverrids and procyonids). The more important infectious diseases of carnivores include rabies, canine distemper, and diseases caused by parvoviruses, coronaviruses and herpesviruses. Few parasitic or bacterial pathogens are significant in captive populations, and appropriate husbandry, therapy, vaccines and quarantine minimize the risk of disease. Extrapolations from one species to another regarding disease susceptibility may be incorrect. The black-footed ferret (Mustela nigripes) serves as an example of a carnivore significantly affected by infectious diseases, some of which were expected while others could not have been predicted from generalized knowledge of diseases of mustelids. This highlights the need to understand the natural history of each species maintained in captivity.
