Ceprologic examination of representatives of 9 monkey species carried out in the Wrocław Zoo revealed the folloving intestinal parasittes: Trichocephalus trichiurus, Strongyloides stercoralis, Nematodirus weinbergi, Ascaris lumbricoides, Enterobius vermicularis and Capillariidae gen. sp. The total extensity of infection was 80%, however intensity was rather low, except for E. vermicularis found in chimpanzees. It seems, that nematoda present the most important problem in control of parasitic infection in zoological gardens.
