Abstract
The article presents the results of a study of the epidemic and epizootic well-being of the West Kazakhstan region on parasitic diseases. In the course of the work, biological and parasitological studies were carried out. Data on the epizootic situation of the spread of ticks, mosquitoes and some helminthiasis in a number of areas of the studied region have been obtained. 6 species of blood-sucking mosquitoes and 6 species of ixodes ticks, 3 types of trematodes: opisthorchiasis, fascioliasis and dicroceliosis, and 1 cestodosis: echinococcosis were studied as having epidemiological significance, their distribution zones were studied, as well as indicators of animal infection with ticks and the level of helminth invasion detected in summer and autumn. The degree of infection of the population of the studied region with echinococcosis and opisthorchiasis was also considered. The work is aimed at scientific provision of epidemic and epizootic well-being for infectious parasitic diseases, development and implementation of databases for modeling and forecasting of parasitic diseases. Studying the dynamics of parasitic insects and helminths in the natural biocenoses of the West Kazakhstan region makes it possible to understand the stability of local ecosystems and identify the main factors of their circulation, helping to prevent the transmission of parasites to pets and humans. The conducted studies have confirmed the high diversity of parasitic organisms in the natural biocenoses of the West Kazakhstan region.
