Start Date: May 15, 2008
End Date: May 14, 2013
Animal infection studies will be conducted with vesicular stomatitis virus (VSV)and exotic bluetongue virus (BTV). The role of Culicoides sonorensis midge saliva in the ability of vesicular stomatitis virus to establish infection, replicate, and persist, will be examined using feral pigs. The physiological variations in VSV infected bats and guinea pigs and their affect on vector-host selection will be determined. The susceptibility of U.S. sheep and white-tailed deer to infection by exotic BTV serotype 8 will be determined. Bite rates, viral transmission, infection rates and pathogenesis will be measured by methods to include: clinical disease observations, virus isolation/plaque assay, polymerase chain reaction, ELISA, ethogram cataloging, videography, necropsy, histopathology, and immunohistochemistry. For all studies, scientists with complementary expertise from both parties will work together to obtain, analyze, and interpret the research data.
