This study aimed to estimate the sero-prevalence and associated with Culicoides trapping in study area in sheep and cattle bluetongue virus sero-positive from seven provinces in North Western Algeria, seven provinces were selected. A total of 255 sheep were used. Three times blood collection in season of autumn were randomly collected for detection of bluetongue virus group specific antibodies through competitive ELISA (c-ELISA) for assessment of situation epidemiological by prevalence and presence of Culicoides trapping in sites was revealed seropositive.
The prevalence of bluetongue virus in sheep was found higher (35,76%) than cattle (16,91), specie new were significantly associated with the occurrence of disease.
