| Summary: | The presence of significant areas used for pastures in Kazakhstan makes it relevant to study the epizootic situation in terms of the incidence of animals during their grazing. The most frequent and dangerous diseases during this period are clostridiosis and listeriosis, which cause significant damage to livestock. Monitoring studies of the dynamics of morbidity among animals for infectious diseases during the grazing period were carried out on the basis of veterinary reporting. Bacteriological studies were carried out in a state laboratory using generally accepted microbiological methods. Analytical and statistical methods were used during the work. Monitoring studies indicate a significant spread of clostridiosis in the territory of Kazakhstan. The highest incidence rate was characterised by emphysematous carbuncle infection, which was recorded throughout the country, with an average frequency of about 40 cases per year. The incidence of braxy and anaerobic enterotoxemia occurred much less frequently and mainly in the southern regions of the country. Listeriosis was also observed only in some regions, but at the same time, a stationary focus of the disease was recorded in the Utylaut region, where cases of the disease are recorded annually. Conducted research made it possible to form the dynamics of the incidence of animals in the pasture period for these diseases, to determine the regions of the country with different intensity of the epizootic situation, as well as to carry out bacteriological isolation of a pure culture of the pathogen from samples taken in the foci of the disease. The studies made it possible to collect information on the features and mechanisms of the occurrence of diseases in the conditions of different regions of Kazakhstan and to develop a multi-vector strategy for preventive measures to eliminate animal diseases during the grazing period.
•Emphysematous carbuncle most widespread in Kazakhstan.•Diseases mainly localised in the country's southern regions.•Negative correlation found between disease manifestation methods.•Clostridial infection pathogens detected in less than 1 % of soil samples.•Study to explore weather and environmental factors in future disease outbreaks. |
