Zoonotic diseases and public health

Bats are reservoirs for viruses with zoonotic potential in the Americas, and scattered evidence exists suggesting that bats may act as reservoirs for dengue virus (DENV). To explore further the role of bats as part of DENV sylvatic cycles, 240 bats of 18 species were captured in 2 states of Mexico with contrasting ecological characteristics but concurrent DENV activity in humans. RT-PCR analysis of RNA extracted from liver or spleen tissue from de bats failed to show evidence for the presence of DENV nucleic acids in these organs. In addition, plasma assayed by plaque reduction neutralization test showed no evidence of neutralizing anti-DENV antibodies. These results suggest that American bats may not be reservoirs or amplification host for DENV infection.
