“…BIV infection has been suspected to be associated with progression of bovine leukemia virus (BLV) [1,9]. The occurrence of this infection was associated with secondary bacterial infections, stresses of parturition and early lactation and/or with unusual environmental stress cofactors, as reported in dairy herds [21]. BIV infection is also associated with decreased milk production shown by a large seroepidemiological study of dairy cows in Ontario, Canada [14].…”

ABSTRACT. A survey of antibodies to bovine immunodeficiency virus (BIV) known as bovine lentivirus and bovine leukemia virus (BLV) was conducted with samples from water buffalo and cattle populations in Pakistan. A total of 370 water buffaloes and 76 cattle were tested, and l0.3% and 15.8%, respectively, were found positive for anti-BIV p26 antibodies determined by Western blotting, while 0.8% of water buffaloes and no cattle were positive for anti-BLV antibodies determined by immunodiffusion test. BIV-seropositive water buffaloes and cattle were found to have BIV proviral DNA in the peripheral blood mononuclear cells determined by nested polymerase chain reaction. This is the first report of BIV infections in water buffaloes.-KEY WORDS: bovine immunodeficiency virus, bovine leukemia virus, water buffalo.

“…However, it has been suggested that BIV infection is associated with decreased milk production in dairy cattle [11], secondary bacterial infection, stressor of parturition and early lactation and/or with unusual environmental stress as cofactors in a Louisiana dairy cattle herd [21]. Thus, information obtained by the surveillance of BIV and BLV infection would be important for cattle industry in Hokkaido and other areas in Japan.…”

“…Since its recognitions as a lentivirus in the late 1980s, seroepidemiological evidence indicates that BIV infection has a worldwide distribution. Serological surveys have shown the presence of seropositive cattle in the USA [23], Canada [11], the Netherlands [10], New Zealand [9], Germany [17], France [20], Great Britain [21], Japan [12], Costa Rica [8], Italy [3], Australia [5], Korea [4], in water buffalo in Pakistan [15], in draught animal in Cambodia [13], Indonesia [1] and Brazil [14]. However, conclusive evidence that BIV causes immunodeficiency in cattle has not been established.…”

ABSTRACT. Serological survey of bovine immunodeficiency virus (BIV) and bovine leukemia virus (BLV) infection was conducted in dairy cattle from 10 different regions of Hokkaido, Japan. Among 390 cattle, 11.0% of cattle were BIV-seropositive and 3.3% were BLV-seropositive. Moreover, in two dairy farms, where bovine leukosis has been reported, prevalence of BIV infections were 6.4 and 9.1%, respectively. In contrast, among 150 beef cattle, 16.6% were BIV-seropositive while none was BLV-seropositive. Dual infections with BLV and BIV in dairy cattle were tested by using 107 BLV-seropositive sera, and 20 sera were found BIV-positive (18.7%). These results indicate that BIV infection was widespread in Hokkaido. KEY WORDS: bovine immunodeficiency virus, bovine leukemia virus, seroepidemiological survey.
