Control And Eradication

    This review was made to explore the recent multiple studies on enzootic bovine leukosis, focusing on its prevalence, economic impact, the link with public health and the possibility to cause cancer in humans. The causative agent of enzootic bovine leukosis is a virus closely related to human T- cell leukemia virus (HTLV-1). The closeness between the two viruses helps the progress of cancer research in diagnosis and treatment, also the development of a vaccine in both human and veterinary medicine .The enzootic bovine leukosis is widely spread in the continents. The economic loses of enzootic bovine leukosis is related to the lowered productivity of effected cattle, morbidity, mortality and cost of control and eradication. This review proved that bovine leukemia virus is innocent from human cancer infection and there is no proof of virus living in human tissues. But this subject needs a lot of research to know the mechanism of the virus and its affects in cellular content of the organism.

And Control

Enzootic Bovine Leukosis (EBL) caused by the bovine leukemia virus (BLV) has been eradicated in over 20 countries. In contrast, the U.S. and many other nations are experiencing increasing prevalence in the absence of efforts to control transmission. Recent studies have shown that BLV infection in dairy cattle has a greater impact beyond the long-recognized lymphoma development that occurs in <5% of infected cattle. Like other retroviruses, BLV appears to cause multiple immune system disruptions, affecting both cellular and humoral immunity, which are likely responsible for increasingly documented associations with decreased dairy production and decreased productive lifespan. Realization of these economic losses has increased interest in controlling BLV using technology that was unavailable decades ago, when many nations eradicated BLV via traditional antibody testing and slaughter methods. This traditional control is not economically feasible for many nations where the average herd antibody prevalence is rapidly approaching 50%. The ELISA screening of cattle with follow-up testing via qPCR for proviral load helps prioritize the most infectious cattle for segregation or culling. The efficacy of this approach has been demonstrated in at least four herds. Breeding cattle for resistance to BLV disease progression also appears to hold promise, and several laboratories are working on BLV vaccines. There are many research priorities for a wide variety of disciplines, especially including the need to investigate the reports linking BLV and human breast cancer.
