Ezatkhah M, Bafti MS, Alimolaei M, Amini M., Prevalence of bluetongue in sheep and goats in Iran, Onl J Vet Res., 27 (6): 367-371, 2023. Blood was taken for bluetongue virus antibody by c-ELISA from 156 sheep and 696 goats located in Kerman, Sistan-Baluchestan and Hormozgan, Iran between January and May on GIS data. We found overall prevalence of ~85% (95% CI: 82.20- 87.05) with ~48% in sheep (95% CI: 37.50-60.00) and ~93% (95% CI: 90.70- 94.70) in goats (P < 0.05), higher in older animals and females (~86%) compared with males (~77%) (P < 0.001). Factors inducing high prevalence are animals in close proximity boosting vector transmission and age, with time of exposure. However, prevalence decreased with age in sheep herds (P<0.05) but increased in goats (P < 0.05). Our findings suggest bluetongue virus is widespread in Iran.
