Amplified ELISA for the detection of western equine encephalitis virus from mosquitoes in Manitoba, Canada.
Current monitoring systems to detect western equine encephalitis (WEE) virus in mosquitoes involve isolation in suckling mice or cell culture followed by serological identification of the isolates obtained. Studies were undertaken to develop an amplified ELISA for the rapid detection of WEE virus from mosquitoes. Virus was inoculated onto primary chick embryo cells in 96 well plates, incubated at 37 degrees C for various time periods, monolayers were fixed, and an ELISA performed. By this procedure, 10 plaque-forming units or greater of WEE virus were detected by 24 h postinfection. This amplified ELISA procedure was successfully applied in parallel with standard isolation methods to monitor mosquitoes collected in Manitoba, Canada, in 1985 for WEE virus.
