摘要：

Venezuelan Equine Encephalitis complex viruses cause epidemics and epizootics periodically in some regions of the Americas. In Argentina, only enzootic Rio Negro virus (AG80-663) (RNV) has been isolated. To survey and identify activity of viruses that belong to Venezuelan Equine Encephalitis complex in a template region of the country, a generic Alphavirus RT-Nested PCR was performed in 99 mosquito pools collected in Chaco province. Five pools were positive, and amplicons were sequenced: four of them clustered with RNV(AG80-663) and one with Pixuna virus. This is the first report of the circulation of Pixuna virus in Argentina, and it confirms enzootic and endemic activity of RNV(AG80-663) in neotropical regions of this country.
