ABSTRACT
Bovine papillomatosis is a common viral infection in Brazil that is caused by a bovine papillomavirus(BPV). Dissemination is by direct contact between infected animals, although the investigation of othermodes of transmission is a very important aspect in the management of this condition. BPV DNA sequenceshave been detected in many tissues by using the polymerase chain reaction. In this work, we used in situhybridization to detect BPV DNA sequences in bovine reproductive tissues and cells. The detection ofBPV in these tissues strongly suggests that these sequences could be an important alternative of viraltransmission that could contribute to the widespread incidence of bovine papillomatosis and its complexpathology. Alternatively, the viral sequences could result from cell apoptosis and may therefore not bedirectly involved in the infection.
