“…It causes enzootic bovine leukemia (EBL) mainly in dairy and beef cattle [ 44 ]. Recently, BLV was found to be in circulation in sheep in Colombia [ 45 ]. Infection affects B cells in cattle, impairs the immune system, reduces milk yield, shortens lifespan, and causes tumor formation in approximately 1–5% of animals [ 46 , 47 ].…”

“…Even if cattle is the natural host of the virus, evidence of the presence of BLV has also been reported in other species (Lee et al, 2012;Barez et al, 2015;Olaya-Galán et al, 2021a). Thus, BLV has been described as a versatile agent that could infect multiple hosts both naturally and under controlled conditions in the laboratory (Gillet et al, 2007).…”

“…Bovine leukemia virus (BLV) is a deltaretrovirus which is able to infect B-lymphocytes in cattle and induces proliferation in these cells, which subsequently leads to enzootic bovine leukosis (EBL) in cattle—a malignant neoplastic disease that mainly involve the lymph nodes, in the form of lymphoma or lymphosarcoma [ 2 ]. Since BLV has been shown to be transmitted to sheep, buffalos and other small ruminants, causing an EBL-like disease in these animals [ 3 , 4 , 5 ], and there are a lot of morphological similarities between EBL and adult camel leukosis, there has been a lot of interest in seeing whether this virus can also lead to adult camel leukosis in dromedaries. Although preliminary studies using PCR amplification for BLV on blood samples of apparently healthy dromedaries have not shown any positive results [ 6 , 7 ], there is still concern as to whether BLV may be associated with adult camel leukosis in dromedaries, as PCR amplification may not be able to pick up BLV or its genetic variants with significant differences from BLV, and the virus may be present in the tissue of dromedaries with adult camel leukosis instead of blood in healthy camels.…”
