A bstract : Approximately 20 sentinel premises in Colorado were visited quarterly during a 3‐year prospective study to investigate the persistence of VS viruses in horses. A survey to assess management practices, health events, animal movements and environmental data was completed at each visit. Collection of serum samples and oral swabs along with a clinical examination of sentinel horses were performed at each visit. Serum samples were tested by 2 or more of 4 available serological tests. The data collected for two years (August 1998 to August 2000) are reported here. During this period there was seroconversion in 1 and 8 horses based on capture IgM tests for seroytpes New Jersey and Indiana, respectively. Kaplan‐Meier curves were generated for those premises with horses that seroconverted and the mean survival time was 4.17 quarters (range 1.85‐7.0). The occurrence of seroconversions during periods when no clinical disease was observed suggests the persistence of vesicular stomatitis viruses in the environment of the sentinel premises.
