摘要：Introduction. Leptospirosis is endemic in Ternopil region. In Ukraine, the disease is registered in almost all regions, includingthe Ternopil region. The aim of the research is to study the regularities of epidemic and epizootic processes of leptospirosis,and the circulation of its pathogens among different sources (small mammals, animals) and humans.Materials and method. Etiologic spectrum of leptospirosis registered in Ternopil region in 1972–2016 among small mammals,farm animals and sick people was studied.Results. Due to the analysis of pathogens circulation among different sources (small mammals, animals), as well as theannual morbidity in humans, it was proved that new leptospira serovars are endemic and brought into the regions mostly byfarm animals. Farm animals introduce the infection to humans through the environment, sometimes within 3–5-years. Thespread was observed of pathogen serovars, which are new in certain areas, among all types of mouse-like small mammalsand rats. It was established that livestock and small mammals are parallel reservoirs.Conclusions. In the regions with endemic species, the structural modification in the etiology of leptospirosis in humans iscaused by additional reservoirs among animals, as well as the circulation of other pathogen serovars that were absent in themain natural reservoir, i.e. mouse-like small mammals and rats. The constant monitoring of the population, contamination andcarrier state of mouse-like small mammals, rats and farm animals, is required In order to predict the future epidemiologicalsituation on leptospirosis among the population and to improve leptospirosis diagnosis.
