CARVALHO, Claudemir de et al. Bovine papillomavirus type 2 in reproductive tract and gametes of slaughtered bovine females. Braz. J. Microbiol. [online]. 2003, vol.34, suppl.1, pp. 82-84. ISSN 1517-8382. http://dx.doi.org/10.1590/S1517-83822003000500028.
Papillomaviruses are described selectively infecting epithelial tissues and are associated with many forms of cancer in different species. Considering the widespread dissemination of papillomatosis in livestock, interest is being centred on possible forms of viral transmission and respective mechanisms. In the present study, we report the detection of bovine papillomavirus (BPV) DNA sequences in female reproductive tract tissues, fluids and oocytes from slaughtered bovines not afflicted by cutaneous papillomatosis. BPV-2 DNA sequences were found in ovarian and uterine tissues as well as in oocytes, cumulus cells and uterine flushings. The presence of papillomavirus sequences in reproductive organ tissues and fluids shows that viral infection in organisms can be verified in others tissues, not only in epithelial ones. The present findings alert to the possibility of BPV transmission in embryo transfer programs and assisted fertilization procedures.
