In this study a serological survey was carried out to detect group specific blue-tongue virus antibodies in sheep and goats serum collected in three ecological regions of Isfahan province of Iran during four seasons of 2005.Blood samples were taken from 7 cities and 109 flocks and 874 sheep and goats randomly. A competitive enzyme linked immunosorbent assay(C-ELISA) was conducted to test the serum samples for blue tongue virus (BTV) group specific antibodies. BTV seropositive reaction were obtained in 451 (51.6%) out of 784 tested sera and in 83.5% (91/109) of the flocks. In the 91 seropositive flocks, the prevalence ranged from 36.2% to 100%.0ut of 504 sheep serum samples and 370 goat serum samples examined ,53.37% and 49.19% respectively were positive. In spring seroprevalence was more than other seasons (p<0.0001).Prevalence of antibody were vary greatly from city to city. There was no difference in seroprevalence among the different ecological regions and different ages. Also there was no difference in seroprevalence between different species and different sexes. Blue-tongue has been never before reported in central area of Iran (Isfahan) and this is the first serological survey for blue-tongue in this region, the results support the conclusion that BTV was widespread in central area of Iran and suggest that it may be endemic and need for further investigation.
