Pirahy virus: Identification of a new and potential emerging arbovirus in South Brazil.

ABSTRACT: Genomic and epidemiological surveillance are paramount for the discovery of new viruses with the potential to cross species barriers. Here, we present a new member of the genus Alphavirus found in Trichoprosopon and Wyeomia mosquitoes, tentatively named Pirahy virus (PIRAV). PIRAV was isolated from mosquito pools collected in a rural area of Piraí do Sul, South Brazil. In vitro assays revealed that PIRAV replicates and causes cytopathic effects in vertebrate cell lines such as Vero E6, SH-SY5Y, BHK-21 and UMNSAH/DF-1. Genomic signature analysis supports these results showing a dinucleotide and codon usage balance compatible with several hosts. Phylogenetic analyses placed PIRAV basal to the Venezuelan equine encephalitis complex. Genome analyses, electron micros
