Seroprevalence of Bluetongue Virus Antibody in Ruminants from Grenada

摘要

The aim of the present study was to estimate the seroprevalence of antibodies to bluetongue virus (BTV) among domestic ruminants of Grenada. Sera samples from cattle (133), goat (314) and sheep (481) were tested using competitive Enzyme-linked immunosorbent assay (c-ELISA). Of the total of 928 samples tested, the overall BTV seroprevalence was 78.4% (95% confidence interval (CI ± 2.65). The seropositivity of ovine, caprine and bovine was found to be 71.7% (95% CI, 67.67% to 75.73%), 80.2% (95% CI, 75.79% to 84.61%) and 98.5% (95% CI, 96.43% to 100.57%), respectively. There was statistical significance in the seroprevalence of BTV among bovine, caprine and ovine (p < 0.05). It is evident from this study that blue tongue virus is endemic in Grenada.
