Abstract

Bovine Leukemia Virus (BLV) is an oncogenic retrovirus that commonly infects cattle and causes B cell leukosis in 1-5% of infected cattle. BLV-infected cells are present in marketed beef and dairy products. The aims of this study were to determine BLV prevalence and the correlation of age, size of herd, common use of needle and veterinarian consultant with prevalence of the infection in SHAHREKORD area, Iran in 2002. A pilot study was also carried out to find whether HUMANs could be infected with BLV.In this study, serum samples of 422 cattle from SHAHREKORD area dairy farms were examined for antibodies to BLV by commercial ELISA test. HUMAN blood sera were tested for anti gp51 antibodies by AGID test. Fifty-nine (14%) samples of cattle were positive in ELISA test. There were statistical correlations between some factors such as common needle use and the size of the herd with the prevalence of BLV in investigated herd (a=0.05). The lowest prevalence was observed in 2-3 year-old COWs and the highest incidence was observed in COWs with more ther 5 years old. No statistical correlation was observed between veterinarian consult with prevalence of BLV in investigated herd (a=0.05).No antibodies to BOVINE VIRAL LEUKOSIS were found positive in 102 serum samples from dairymen of the farms. So this study failed to reveal any relationship between bovine leukosis and HUMAN. However, we suggest that further studies in this area could be important.
