Abstract

This paper presents an analysis of the parasite fauna of Javanese macaques kept in captivity in the conditions of the Adler nursery of the FGBNU «NII MP». In the course of the parasitological study, 245 Macaca fascicularis monkeys were examined. As a result, it was revealed that they have 44,5 varieties of worms of the nematode class: Ancylostoma spp., Trichoceephalus spp., Strongyloides spp., Oesophagostomum spp., As well as XNUMX species of protozoa: Balantidium coli, Blastocystis spp. and Lamblia intestinalis. During the analysis of the data obtained, it was found that the total invasion of the studied animals was XNUMX%.
It was found that the most common types of helminths found in the studied animals are Strongyloides spp., Parasitizing in the duodenum and upper jejunum of mammals, the extent of invasion was 6,9%. Of the protozoa, the species Balantidium coli, parasitizing in mammals in the large intestine, was most often found; the extent of invasion was 18,8%.
The extensiveness of the invasion of Ancylostoma spp., Localized in the small intestine, in the studied cynomolgus macaques was 5,7%, Blastocystis spp., Found in the cecum and proximal colon, 2,9%, Trichoceephalus spp., Parasitizing in the blind part of the intestine, – 3,3%, Oesophagostomum spp., penetrating into the mucous membrane and submucosa of the large intestine, – 0,8%.
Also, the studied macaques were found to have combined invasions.
Extensiveness of invasion of Balantidium coli simultaneously with Strongyloides spp. was 0,8%, Balantidium coli simultaneously with Trichoceephalus spp. – 1,2%, Balantidium coli simultaneously with Ancylostoma spp. – 0,4%, Balantidium coli simultaneously with Blastocystis sp. – 0,4%, Balantidium coli simultaneously with Oesophagostomum spp. and Trichoceephalus spp. – 0,4%, Strongyloides spp. simultaneously with Lamblia intestinalis – 0,4%, Strongyloides spp. simultaneously with Trichoceephalus spp. – 1,2%, Blastocystis sp. simultaneously with Ancylostoma spp. – 0,4%, Blastocystis spp. simultaneously with Trichoceephalus spp. – 0,4%, Trichoceephalus spp. simultaneously with Ancylostoma spp. – 0,4%.
