infections are widespread and highly prevalent in rodents. Several rodent-associated species have been related to human diseases. Recently, species was reported as the etiology of a human case in the country of Georgia (Caucasus). However, information on in rodents in Georgia is absent. Rodent hearts were collected from Georgia to investigate the presence and diversity of species. bacteria were cultured from 37.2% (16/43) of rodents examined, while DNA was detected in 41.2% (28/68) of rodents by polymerase chain reaction targeting citrate synthase () gene. Sequences of showed that rodents in this region harbored multiple strains, including , , , and an unknown genogroup. The first three species, known to be rat-associated and human cases linked, were commonly observed in wood mice ( [] ) (5/8 positive with and ) and social voles () (4/6 positive with and ) in this study. The frequent distribution of these species suggests that they may contribute to unidentified clinical infections. The unknown genogroup was observed in 24 isolates and/or DNA extracts from heart tissues, all of which were obtained from (). Further characterization of the bacterial cultures based on sequence analysis of four additional genes (, , , and ) supported that the jird-associated strains comprise a distinct monophyletic clade. The impact of this bacterium on wildlife and human health needs to be determined.
