Abstract
This article presents the results of statistical data as of July 1, compared with the same date last year, the number of horses as a whole increased by 8.5%, amounting to 3372.5 thousand heads as of July 1. However, during the winter months (January and February), the number of horses in Kazakhstan decreased by 1.3%. In absolute terms, the number of horses in January decreased by 20.2 thousand heads, and in February by another 16.6 thousand heads. In recent years, the country has seen an increase in the incidence of mytomy not only among foals, but also among adult livestock. In order to conduct epizootological monitoring of washing of horses, according to the calendar plan of the project IRN 08855635, from 2020-2022 scientific expeditions were organized on the territory of the Almaty region of the republic with the sampling of pathological material from sick animals. As a result of the purposeful organization and conduct of expedition trips, the necessary epidemiological data were collected and the analysis of ongoing veterinary and sanitary measures was carried out. As a result of this stage, samples were collected in a total of 112 samples of biomaterial from sick washed foals during sowing, it was possible to isolate the culture of the microbe only in 3 cases. This circumstance is due to the fact that the modified forms of mytaceous streptococcus causing atypical cases of the disease are very difficult to cultivate. According to the results of the study, bacterial isolates were identified as the species Streptococcus equi.
