摘要：

St Louis encephalitis virus (SLEV) is a re-emerging human pathogen widely distributed in the American continent. Although it is not fully understood, the SLEV transmission network may involve Culex quinquefasciatus mosquitoes as vectors and Columbidae species as hosts. To calculate infection rates, we inoculated Cx. quinquefasciatus mosquitoes from Crdoba, Argentina by feeding them on viremic chicks. We observed differences in infection rate among the viral strains, the highest rate (78/87 mosquitoes, 90.8) being seen in strain 78V-6507. After re-feeding on susceptible chicks, mosquitoes were able to transmit the virus. Our findings suggest that Cx. quinquefasciatus populations are susceptible to and able to transmit different SLEV strains.
