SARAULLO, Vanina et al. First report of pathogenic Leptospira spp. in Tadaridabrasiliensis bats (family Molossidae) and Eptesicus furinalis (family Vespertilionidae) of Argentina. New host species in this country?. Rev. argent. microbiol. [online]. 2021, vol.53, n.3, pp.31-40. ISSN 0325-7541.

Leptospirosis is an endemic disease caused byLeptospiraspp., a bacterium that affects animals and humans. In recent years, the number of reports of leptospirosis in wild animals has increased, which highlights the need to study the infectious agents in these animals. In this study, a duplex PCR for the detection of leptospiral DNA was performed on 50 kidney samples from bats, and a MAT (Microscopic Agglutination Test) for serological detection of anti-leptospiral antibodies was applied to 47 serum samples from bats from different regions of Buenos Aires Province, Argentina.

DNA was extracted using Chelex-100 and duplex PCR was performed by targeting the detection of genessecYandflaB, of pathogenicLeptospiraspp. Of the 50 kidney samples, 3 were positive forEumopssp. andTadaridabrasiliensisby duplex PCR. Of the 47 serum samples, 12 were positive for different serovars:Leptospira interrogansserovars Icterohaemorrhagiae, Cynopteri and Bataviae, andLeptospira borgpeterseniiserovar Ballum. This is the first report of the detection of pathogenic leptospires by serology in bats belonging to theT. brasiliensisandEptesicus furinalisspecies in Argentina. In addition, this is the first report of the detection of pathogenic leptospiral DNA by PCR inT. brasiliensisspecies. The detection ofLeptospiraspp. in these wild animals shows that they may play an important role as wildlife reservoirs of leptospires.
