Evaluation of an enzyme-linked immunosorbent assay for detection of antibodies to vesicular stomatitis virus in cattle in an enzootic region of Mexico.

An ELISA was compared with the plaque-reduction serum neutralization (PRSN) test, for detection of vesicular stomatitis virus (VSV) antibodies in cattle in a vesicular stomatitis enzootic region of Mexico. A total of 325 bovine serum samples were screened for VSV antibodies. The PRSN test was performed, using Vero cells. The ELISA contained gradient-purified VSV Indiana (Lab strain) and VSV New Jersey (Hazelhurst) as the antigens. Regression analysis and weighted kappa statistic were used to estimate measures of agreement between the 2 assays for detection of VSV antibodies. The ELISA method proved useful for serodiagnosis of vesicular stomatitis. The ELISA and PRSN test results were highly correlated for detection of VSV antibodies.
