Helminthofauna of digestive tract of domestic reindeer Western Taimyr

Abstract

Here are the results of monitoring studies of the helminth fauna of the digestive tract of domestic reindeer from breeding farms of Western Taimyr in the period 2014-2016. Monitoring studies include laboratory work with biological material from 428 reindeer, collected during the spring and autumn with conventional techniques, including gelmintoovoskopy, gelmintolarvoskopy and gelmintoskopy. The authors found that the Western Taimyr population of domestic reindeer is characterized by the presence of 13 species of helminthes, belonging to 3 classes, 9 genera and 5 families. The publication reviewed the results of studies on cestodosis, nematodes and trematodes. Studies have determined a high infestation by ostertagiosis and monieziasis as in the associated invasions and monoinvasion. Most common are associations Ostertagia spp., Nematodirus sp., Moniezia spp. in several variations. For example, the dynamics of livestock contamination in the 2014-2016 by ostertagiasis confirmed the effect of climatic characteristics of the region on the degree of animals infestation. Analysis of the data indicates the effect of reindeer on the total epizootic situation in the region as a "reservoir" of helminth diseases and the importance of continuous monitoring of helminth infections of domestic reindeer.
