[Data on intestinal parasites of lower monkeys in the Adler apery]

Under captive conditions, a parasite fauna connected with the changes in ecological conditions, feeding, and mode of life is usually formed in monkeys. Species composition of the intestinal parasites has been investigated in six species of the monkeys (Macaca mulatta, M. fascicularis, M. nemestrina, Ceropithecus aethiops, Papio hamadryas, and P. anubis), which were born in the Adler apery and live there for a long time. A comparison with similar investigations carried out in the Sukhumi apery, where the climatic and keeping conditions are practically identical with those in the Adler apery, was conducted. Parasite fauna of monkeys in the Adler apery was found to include three species of Nematoda (Ascaris sp., Trichocephalus sp., and Strongyloides sp.) and two species of Protozoa (Balantidium coli and Lamblia intestinalis). In our material, Trichocephalus sp. is the dominant parasite species among helminthes, and Balantidium coli is the most frequent species of Protozoa. The commonness in the transmission of these parasites and similarity in their life cycles contribute to the forming of polyinvasions in monkeys.
