Seroprevalence of bluetongue virus infection in goats in the central China

ABSTRACT

Seroprevalence of Bluetongue virus (BTV) in goats from Hubei was investigated by a commercial competitive enzyme-linked immunosorbent assay kits. Blood samples (n= 1157) were collected during the year 2014 and 2015. The results showed that 13.31% (CI 95% 11.4%–15.4%) serum samples were positive for BTV antibodies in goats in Hubei. The prevalence of BTV antibodies in each region ranged from 1.32% to 27.70%, and differences among the regions were statistically significant (p 0.05). In different seasons, the seroprevalence were 8.94% (95% CI 5.6, 13.3) in spring; 18.31% (95% CI 14.5, 22.7) in summer; 23.08% (95% CI 17.0, 30.2) in autumn and 6.98% (95% CI 4.6, 10.0) in winter, respectively with a significant difference of the prevalence in the different seasons (p < 0.01).
