Transmission of a Venezuelan equine encephalitis complex alphavirus by Culex (Melanoconion) gnomatos (Diptera: Culicidae) in northeastern Peru
Journal of Medical Entomology 42 (3), 404-408
Abstract: Venezuelan equine encephalitis (VEE) complex alphaviruses are serious health threats in the Americas and regularly infect humans living in or near Amazonian rain forests. As part of a larger surveillance program, we placed six hamster-baited mosquito traps in a disturbed white sand forest of northeastern Peru for 3d. Virus isolations from hamster serum and trapped mosquito pools demonstrated that a VEE subtype III Calphavirus was transmitted to a hamster by the mosquito Culex (Melanoconion) gnomatos Sallum, Hutchings and Ferreira. This species, like the other seven proven VEE complex alphavirus vectors, is a member of the Spissipes section of this subgenus. The composition of mosquitoes collected at the site over the sampling period was typical for the region.
Encefalitis equina venezolana (EEV) es una enfermedad emergente e importante enlas Américas, y confrecuencia afecta a los seres humanos que viven en o cerca de la cuenca amazónica. Como parte de una extensa investigación sobre la distribución de EEV en la amazonía peruana, seis trampas usando hamster como cebo fueron colocadas por tres días en un bosque secundario sobre suelos de arena blanca, ubicado a 10Km al suroeste de la ciudad de Iquitos. Losvirus aislados del suero de un hamstery de los mosquitos indicaron que EEV subtipo IIIC fue transmitido a un hamster por el mosquito Culex (Melanoconion) gnomatos Sallum, Hutchings and Ferreira. Esta especie, comolas otras siete especies conocidos vectores del complejo alphavirus, es un miembro de la sección Spissipes del subgénero. La composición de los mosquitos colectadosen el área fue típica de la región.
