Seroprevalencija zaraznog rinotraheitisa goveda u krava s pobačajem u Alžiru

Abstract

In this study, the possible effect of bovine herpes virus 1 (BHV-1) on abortions in selected dairy herds in the Mitidja plain of Algeria was investigated serologically. Serum samples obtained from 460 aborted cows, where frequent abortions occurred during the second and third trimester of gestation during the period July 2018 to July 2019, were analysed for the presence of specific antibodies for BHV-1 using the ELISA technique. The results revealed an individual seroprevalence of 43.7% (201/460) of the tested samples were positive for BHV-1 specific antibodies by ELISA, and a herd seroprevalence of 68.7% (110/160). According to our results, BHV-1 may be responsible for the abortions encountered in the tested cattle, which may indicate the presence of persistentlyand permanently infected animals in Algerian dairy cattle farms. In order to control bovine abortions caused by BHV-1, vaccination campaigns should be carried out before the cattle are released for breeding.
