Diseases of tropical origin in captive wild animals

Abstract

Diseases of tropical origin in captive wild animals resemble closely many seen in man. However, many conditions familiar in animals in the wild are not encountered. The absence of an intermediate host from the strange environment is an obvious factor limiting the spread of many parasites. However, many conditions not demanding such vectors are not seen either. The high mortality among sick animals on the journey to temperate climates may account for much of this. Thus, the amount of material available in captive wild animals is small, but its study is of great interest from the general aspect, as well as assisting the understanding of natural infections of man and animals. New hosts for parasites, and the length of time for which some infestations may persist in the absence of an essential vector, are some of the points that can be studied. Individual animals can be observed with a thoroughness that is not often possible in the field.
