transmission of west nile virus by culex quinquefasciatus say infected with culex flavivirus izabal.the natural history and potential impact of mosquito-specific flaviviruses on the transmission efficiency of west nile virus (wnv) is unknown. the objective of this study was to determine whether or not prior infection with culex flavivirus (cxfv) izabal altered the vector competence of cx. quinquefasciatus say for transmission of a co-circulating strain of west nile virus (wnv) from guatemala.201020454569
west nile virus ecology in a tropical ecosystem in guatemala.west nile virus ecology has yet to be rigorously investigated in the caribbean basin. we identified a transmission focus in puerto barrios, guatemala, and established systematic monitoring of avian abundance and infection, seroconversions in domestic poultry, and viral infections in mosquitoes. west nile virus transmission was detected annually between may and october from 2005 to 2008. high temperature and low rainfall enhanced the probability of chicken seroconversions, which occurred in both ...201223149586
host selection of potential west nile virus vectors in puerto barrios, guatemala, 2007.the selection of vertebrate hosts by culex mosquitoes relative to west nile virus (wnv) transmission in neotropical countries such as guatemala is not described. this study determined the feeding patterns of cx. quinquefasciatus and cx. nigripalpus and estimated the relative contribution of two common and frequently infected wild bird species, turdus grayi and quiscalus mexicanus, to wnv transmission. engorged mosquitoes were collected from rural and urban habitats after the dry and wet seasons ...201223208881
