The main part of this dissertation deals with diseases of hyenas in the literature available and compares these findings with those of captured animals. For this purpose zoological gardens in Switzerland, Austria, The Netherlands and Germany were asked for support. As hyenas are not visitors favourite animals in zoos, it is surprising to find more than two hundred sources of literature and reports of fourteen zoological gardens with 97 results to evaluate.

Diseases of the reproductive tract, respiratory tract, traumas, neoplasms, the circulary system, the digestitive tract, the urinary tract, endocrinological and central organs occur in different frequencies. For the first time results from the circulary system, the kidney, the respiratory system and the male genitaltract are listend.
