| genetic diversity and relationships among venezuelan equine encephalitis virus field isolates from colombia and venezuela. | during field studies of enzootic venezuelan equine encephalitis (vee) viruses associated with epizootic emergence, a large number of virus isolates were made in sylvatic foci of venezuela and colombia. to rapidly characterize these isolates, antigenic subtypes were determined by means of immunofluorescence and by single-strand conformational polymorphism (sscp) analysis by use of an 856-bp fragment from the p62 gene, which we used to distinguish genetic variants. representative isolates were seq ... | 2001 | 11791968 |
| [mosquitos (diptera: culicidae) in the small village where a human case of venezuelan equine encephalitis was recorded]. | the enzootic focus of subtype id of venezuelan equine encephalitis (vee) virus in the central magdalena region (central colombia) occasionally produces human cases. the report of a vee infection in a three-year-old girl in the small chingalé, municipalitype of puerto wilches, santander, motivated this study. | 2008 | 18719725 |
| natural enzootic vectors of venezuelan equine encephalitis virus, magdalena valley, colombia. | to characterize the transmission cycle of enzootic venezuelan equine encephalitis virus (veev) strains believed to represent an epizootic progenitor, we identified natural vectors in a sylvatic focus in the middle magdalena valley of colombia. hamster-baited traps were placed into an active forest focus, and mosquitoes collected from each trap in which a hamster became infected were sorted by species and assayed for virus. in 18 cases, a single, initial, high-titered mosquito pool representing t ... | 2003 | 12533281 |
