Molecular characterization of bovine leukemia virus detected in dairy cattle herds from the Emirate of Abu Dhabi, United Arab Emirates.

ABSTRACT: Enzootic bovine leukosis (EBL) is an economically important disease of cattle caused by the bovine leukemia virus (BLV). Although BLV-seropositive dairy cattle were previously reported in the Emirate of Dhabi, UAE (EAD), molecular characterization of circulating BLV strains has not been undertaken. Therefore, the objectives of this study were to reassess the seroprevalence along with evaluating the genetic diversity of BLV strains circulating in dairy cattle in the EAD. Sera from 782 dairy cattle distributed across 11 farms were ELISA-screened and RT-qPCR testing of seropositive samples was followed by Sanger sequencing of the partial BLV env-gp51 gene (~ 423 bp) and phylogenetic analysis. The overall BLV herd seroprevalence was 27.3% (CI: 6.03%-61.00%), mean animal seroprevalence 33.5% (C
