Materials and methods. The study was conducted by the method of epidemiological analysis using reporting data. Blood serum samples of people and farm animals, field material and environmental objects from anthropological (economic) foci were examined using modern laboratory methods.
Results. In 2022, 27 cases of Q fever were registered in 4 districts of the Rostov Region. The victims were mainly men of working age, residents of rural areas. Most patients were infected in anthropogenic foci formed in private subsidiary farms (PSF) and agricultural enterprises. During the epizootological survey conducted in natural biotopes, isolated finds of Coxiella burnetii were detected. In 28.6% of samples of material collected in anthropogenic foci, the pathogen DNA was detected. According to the results of studying the immune layer of the population of the Salsky and Remontnensky districts, the proportion of seropositive individuals was 3.0 and 1.3%, respectively. The pathogen was cultured on the Vero E6 cell line and a biological sample was set up. A culture of C. burnetii was isolated from the patient’s blood serum.
Conclusion. The current epidemic situation with Q fever in the Rostov Region is determined by periodically registered cases of human disease. Patients were identified in the southeast of the region in areas with a developed livestock farming structure. The epidemic process is caused by the formation of anthropogenic foci in private subsidiary farms and agricultural enterprises.
