AN ABATTOIR SURVEY ON PREVALENCE OF ENZOOTIC BOVINE LEUKOSIS VIRUS INFECTION AND ASSOCIATED CLINICAL, HAEMATOLOGICALAND FLOW CYTOMETRIC FINDINGS IN HOLESTEIN CATTLE IN TEHRAN

Bovine leukosis virus (BLV) is a retrovirus that primarily affects lymphoid tissue of cattle. To determine the seroprevalence of Enzootic Bovine Leukosis Virus infection and its effects on some clinical, hematological and flow cytometric indications, this study was conducted on 197 Holstein cattle slaughtered in an abattoir in Tehran province. ELISA gp51 test of the obtained serums of the animals showed that the mean of infection rates was 22.3%. Age arrangement of the relative frequencies of the infection showed a significant correlation between EBLV infection and age increasing (0.001
