Abstract
The vesicular stomatitis virus belongs to the Rhabdoviridae family, genus Vesiculovirus. Four species (New Jersey, Indiana, Cocal, and Alagoas) are responsible for disease outbreaks in Western Hemisphere countries. In Brazil, the Alagoas virus is responsible for the main outbreaks of the disease, mainly in the states of the Northeast, Midwest, and Southeast regions of the country. The present study aimed to perform the genetic characterization of 41 vesicular stomatitis virus samples. RNA was extracted using Trizol and used to amplify part of gene P. Amplicons were sequenced using the Sanger method. The phylogenetic trees generated showed that Alagoas vesiculoviruses were positioned into three groups: group A formed by the first virus isolate; group B by isolates from states in the Northeast region; and group C by isolates from the states of Bahia, Goiás, and Tocantins. Their divergence to date has generated the formation of two genotypes evolving independently in regions that until the present study had little geographic overlap.
