| 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 |
