Abstract:
In the present study the prevalence of antibodies to enzootic bovine leucosis virus were estimated using a commercial ELISA test in Riyadh, Al-Hasa and Qassim regions of the KSA. A total of 2024 serum samples were tested for the prevalence of antibodies to enzootic bovine leucosis virus. The prevalence percentage of enzootic bovine leucosis virus antibodies was 23.36 {6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465} (473 out of 2024). According to age samples studied prevalence percentages of 17.26 {6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465} (105 out of 608), 15.02 {6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465} (61 out of 406) and 30.40 {6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465} (307 out of 1010) were obtained for animals aged less than one year, 1-2 years and more than two year respectively. The effect of sex on the prevalence of enzootic bovine leucosis virus was studied and prevalence percentages of 16.76 {6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465} (184 out of 1098) and 31.21 {6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465} (289out of 926) were obtained for male and female respectively. It can be concluded that enzootic bovine leucosis virus is widely distributed in cattle in KSA. These finding recommend the adoption of test and slaughter control program for the serologically positive animals. Testing of new introduced animals is very important in order to minimize the rate of infection.
