Antibodies Related to Borrelia burgdorferi sensu lato, Coxiella burnetii, and Francisella tularensis Detected in Serum and Heart Rinses of Wild Small Mammals in the Czech Republic

Wild small mammals are the most common reservoirs of pathogenic microorganisms that can cause zoonotic diseases. The aim of the study was to detect antibodies related to Borrelia burgdorferi sensu lato, Coxiella burnetii, and Francisella tularensis in wild small mammals from the Czech Republic. In total, sera or heart rinses of 211 wild small mammals (168 Apodemus flavicollis, 28 Myodes glareolus, 9 A. sylvaticus, and 6 Sorex araneus) were examined by modified enzyme-linked immunosorbent assay. Antibodies related to B. burgdorferi s.l., C. burnetii, and F. tularensis were detected in 15%, 19%, and 20% of animals, respectively. The prevalence of B. burgdorferi and F. tularensis statistically differed in localities and F. tularensis also differed in sex. Antibodies against 2–3 pathogens were found in 17% of animals with a higher prevalence in M. glareolus. This study brings new data about the prevalence of the above-mentioned pathogens.
