ESPINOZA-GOMEZ, Aldo et al. Identification of viral RNA sequences in vampire bats (Desmodus rotundus) from central Mexico. Rev. Mex. Biodiv. [online]. 2022, vol.93, e934021.  Epub Dec 12, 2022. ISSN 2007-8706.  https://doi.org/10.22201/ib.20078706e.2022.93.4021.

Bats are important reservoirs of viral entities that cause diverse economical and health problems in several sectors. The purpose of this study was to determine the prevalence of the rabies virus in vampire bats. We also tested for 3 other zoonotic viruses in the collected tissue. We captured 45 vampire bats (Desmodus rotundus), which were measured and sexed under standard parameters. We followed an RT-PCR reaction to amplify the viral products of four virus types: chikungunya (CHIKV), dengue (DENV), rabies (RABV) and Zika virus (ZIKV) from cerebral tissue. We obtained an amplicon of 100 bp for ZIKV in 2 samples, representing a prevalence of 4.4%. An amplicon of 581 bp for RABV was observed in 9 individuals, which is equivalent to 20% of our sample. We obtained 4 different haplotypes for RABV and a single haplotype for ZIKV. We did not record the presence of DENV and CHIKV. We corroborated the presence of the family Rhabdoviridae in the vampire bat and recorded the presence of ZIKV for the first time in this bat species.
