Cattle influenza D virus in Brazil is divergent from established lineages

Abstract

Influenza D virus (IDV) is endemic in cattle on several continents and can also infect a wide range of hosts. IDV was first detected in a bovine respiratory disease outbreak associated with bovine alphaherpesvirus 1 in Brazil. Sequence analysis of partial segments showed that the virus is phylogenetically divergent from previously described IDVs from other continents. As the first molecular description of IDV in South America, this can be a first step toward investigating IDV infections in cattle in Brazil and surrounding countries in which the beef industry is economically important.
