| Description |
Background. Ternopil region is endemic on leptospirosis. Its natural conditions (slightly alkaline or alkalinesoils, air temperature, sufficient rainfall) contribute to the existence of major natural reservoir of the pathogen –mouse-like rodents. In the region, different serovariants of leptospira are exuded by rodents and farmanimals.Objective. The materials of the Department of Highly Infectious Diseases of Ternopil Regional LaboratoryCentre of the State Sanitation and Epidemiological Service of Ukraine, Ternopil Regional Laboratory of VeterinaryMedicine, Clinic of Infectious Diseases of TSMU were studied.Leptospiras were detected by dark ground microscopy (DFM) of blood of patients, trapped rodents and examinedfarm animals.Results. The circulating of pathogens between different sources (rodents, animals) and annual �����������disease incidenceevidences that new leptospira serovar are carried onto endemic area mostly by farm animals; humansare infected from them through the environment sometimes in 3-5 years intervals; the further diffusion to thenew areas of this pathogen serovars in all kinds of the examined mouse-like rodents is noticed.It is established that farm animals and rodents are competing reservoirs. To predict the future epidemiologicalsituation of leptospirosis among the humans and to improve its diagnosis the constant monitoring of thepopulation, infection and leptospira carriage among mouse-like rodent and farm animals and expanding of thepanel of diagnostic leptospira strains including new pathogen variants in animals is necessary.Conclusions. The development of additional reservoirs in animals, with circulating of other pathogenserovars among them, such as mouse-like rodents, which were previously absent in the main natural reservoir,cause the change of etiological structure in human leptospirosis at the endemic areas. The range of humanleptospirosis pathogens and its further spreading among all kinds of rodents increased during our research. Theresults of detection of leptospirosis pathogens among the various contingents which were studied evidence thatthe farm animals and rodents are competing reservoirs that cause human infection through environment.KEY WORDS: leptospirosis, disease incidence, source of infection, rodents, farm animals.
