| genetic and evolutionary characterization of venezuelan equine encephalitis virus isolates from argentina. | venezuelan equine encephalitis viruses (veev) are emerging pathogens of medical and veterinary importance circulating in america. argentina is a country free from epizootic veev activity, with circulation of enzootic strains belonging to rio negro virus (rnv; veev subtype vi) and pixuna virus (pixv, veev subtype iv). in this work, we aim to report the sequencing and phylogenetic analyses of all argentinean vee viruses, including 7 strains previously isolated from mosquitoes in 1980, 5 sequences ... | 2014 | 24833218 |
| venezuelan equine encephalitis viruses (veev) in argentina: serological evidence of human infection. | venezuelan equine encephalitis viruses (veev) are responsible for human diseases in the americas, producing severe or mild illness with symptoms indistinguishable from dengue and other arboviral diseases. for this reason, many cases remain without certain diagnosis. seroprevalence studies for veev subtypes iab, id, if (mosso das pedras virus; mdpv), iv (pixuna virus; pixv) and vi (rio negro virus; rnv) were conducted in persons from northern provinces of argentina: salta, chaco and corrientes, u ... | 2013 | 24349588 |
| cocirculation of rio negro virus (rnv) and pixuna virus (pixv) in tucumán province, argentina. | venezuelan equine encephalitis complex includes viruses considered emerging pathogens for humans and animals in the americas. two members of this complex have been detected previously in argentina: rio negro virus (rnv), detected in mosquitoes from chaco province and rodents from formosa province, and pixuna virus (pixv), detected in mosquitoes from chaco province. to carry out surveillance studies in other parts of the country, detection of a 195-bp fragment of alphaviruses by rt-nested pcr was ... | 2010 | 20497404 |
| enzootic activity of pixuna and rio negro viruses (venezuelan equine encephalitis complex) in a neotropical region of argentina. | 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 ... | 2010 | 19402767 |
