Cross-sectional study on Brucella spp., Leptospira spp. and Salmonella spp. in bats from Montes Claros, Minas Gerais, Brazil

The understanding on the role of bats in the ecology of zoonotic diseases, especially its relevance as a carrier of pathogens, is important for the determination of preventive measures considering the One Health context. The present study aimed to investigate the presence of Brucella spp., Leptospira spp. and Salmonella spp. in blood (n = 163), liver (n = 35) and spleen (n = 62) samples from bats captured in Montes Claros, Minas Gerais, Brazil. Only Salmonella spp. was found in a blood sample of an insectivorous female bat of the species Lasiurus blossevilli, evidencing the capacity of this animal species to host this pathogen. In conclusion, our results in bats from Montes Claros indicate that they do not act as hosts for Brucella spp. and Leptospira spp., although being potential carriers of Salmonella spp. in a low prevalence.

Automated summary

This study found Salmonella spp. in bat samples from Montes Claros, Brazil, indicating the capacity of bats to carry this pathogen. However, bats in the area were not found to be hosts for Brucella spp. and Leptospira spp.
