Actividad del virus de la encefalitis equina venezolana en el norte de Colombia, abril y mayo de 1983
MetadataShow full item record
Venezuelan equine encephaltis (VEE) virus was isolated from sentinel hamsters exposed in the Rio de Oro region of Colombia, in the Lake Maracaibo drainage area near the border with Venezuela, in 1983-13 years after the first strain was isolated from the region near Tibu. Hydroxylapatite elution profiles of three isolates from the Rio de Oro region were typical of enzootic strains. Relative abundance data and past isolations suggest that culex (Melanoconion) pedroi is a probable enxootic vector at this focus. The virus was no isolated from forests near Santa Marta and Magangue in the Rio Magdalena drainage area in 1983-9 and 16 years, respectively, after the last previous isolations in those areas. However, equine animals 2 to 10 years of age and humans 25 to 67 years of age living near the Magangue field study area were positive for VEE virus-specific neutralizing antibodies
