Abstract

Introduction. Wild pigs (Sus scrofa) are an essential part of the fauna in many countries of the world. The populations of these free-living pigs represent not only ecological chellanges, but also poses a risk of infectious diseases spreading as well. Wild pigs carry many infectious agents that can be transmitted to domestic pigs and other animals, including humans. These animals are omnivorous; they consume rodent corpses; infect pastures and water places in nature. Wild pigs become reservoirs and carriers of pathogenic leptospira, infected from contaminated reservoirs and mouse-like rodents, when thus posing a direct threat to agricultural and domestic animals and humans. The goal of the work was to study leptospirosis infection, its prevalence and etiological structure of this zoonosis among wild pig population in Ukraine. Materials and methods. Were examined a total of 516 blood sera samples of wild pigs and tested for Leptospira spp. using an microscopic agglutination test (MAT), which was conducted with 21 Leptospira`s serological groups. Results of research and discussion. According to numerous publications of scientists from different countries of the world, the seroprevalence level of leptospirosis infection among wild pig population varies from 3% to 95%. Taking into account the results of our own research, Ukraine occupies the second position in this list and is keep on registering in wild pigs. A total of 516 samples of blood serum were studied in the microscopic agglutination test. We analyzed obtained the results in tests by oblasts of Ukraine. In the vast majority territory of country, particular 13 ones, the percentage of positive reactions varied within 80–89%, which indicates a significant infection of wild pigs with pathogenic serogroups of Leptospira. In 8 oblasts this percentage ranged 90–100%. Only in 3 oblasts the percentage of infection remained at the level of 70–79%. As a result of the serological study, 448 animals reacted positively, which is 86.8% of the total number of investigated ones. Analyzing the overall etiological structure of positively reacting to wild pigs, the antibodies to the serotypes Icterohaemorrhagiae (22.4%), Australis (serovar bratislava) (18%) and Ballum (8.4%) were detected most frequently. Pomona (6.4%) and Hebdomadis (6%) registered less. Other serological groups ranged from 2.1% to 5.4%. The most insignificant etiological role were played by serogroups Cynopteri (1.2%) and Panama (1.6%). Conclusions and prospects for further research. Summing up the aforesaid, according to the results of our work, serological prevalence of the pathogenesis of leptospirosis among wild pig populations was determined to be 86.8%. Was detected the circulation of Leptospira's antibodies in blood serum of these animals. The analysis of the etiological structure of leptospirosis showed that the dominant serogroups were Icterohaemorrhagiae, Australis (serovar bratislava), Ballum, Pomona, and Hebdomadis. The most important etiological role were played by serogroups: Panama, and Cynopteri.
