Abstract

We examined the teats of slaughtered cattles to investigate the prevalence of papilloma and to detect bovine papilloma virus (BPV) from those samples. Among 880 heads, 432 (49.0%) was Holstein and 448 (51.0%) was Korean native cattle. Grossly, out of 432 heads (Holstein), 263 (60.8%) had papilloma lesions on teats. However, out of 448 heads (Korean native cattle), only 33 (7.4%) had papilloma lesions on teats. Immunohistochemically, BPV antigen was detected in 35 heads (22.9%) of 153 (Holstein) which had papilloma lesions. But, in Korean native cattle, BPV antigen was detected in 1 head (3.8%) of 26. Electronmicroscopically, in Holstein papilloma cases, BPV particles was detected in 31 heads (39.2%) of 79. This study revealed that papilloma was very prevalent in holstein teats, Korea and the prevalence of papilloma in Holstein was 8 times higher than that of Korean native cattle. Moreover, it was needed to consider gross and histopathological lesions to confirm BPV infection on teats because the sensitivity of immunohistochemistry and electronmicroscopy was not high.
