Serological monitoring of bacterial zoonotic pathogens in Kharkiv region (Ukraine) for 2011-2024

The aim of study was to determine the spread of bacterial zoonoses on livestock farms and in the private sector of the Kharkiv region (Ukraine) based on the results of serological monitoring. The study was conducted at the Kharkiv Regional State Laboratory of the State Service of Ukraine for Food Safety and Consumer Protection, covering the period 2011-2024 using methods of retrospective, statistical, structural and epizootic analysis. The results obtained allowed us to assess the infection of the livestock with bacteriosis and install the intensity of the epizootic process in the Kharkiv region with regard to bacterial infections among animals based on the results of the study of the sample 3461694 blood sera from animals of various species. According to the results of the research, antibodies to the causative agents of leptospirosis, brucellosis, infectious epididymitis of sheep, and chlamydia were detected in 75,251 animals. The results obtained allowed us to assess the infection of the livestock which it possible to establish the intensity of the epizootic process in the Kharkiv region with regard to bacterial infections among animals. Military operations in the region, which were launched by Russia, do not allow for the full implementation of appropriate veterinary and sanitary measures to limit the circulation of relevant pathogens. The results obtained justify proves the need to continue regular serological monitoring of diseases of bacterial aetiology in order to maintain public and timely prevention of zoonotic diseases.
