| Resumo: |
Cutaneous papillomatosis is a pathological condition commonly found in cattle and is characterized by the presence of benign proliferative tumors caused by bovine papillomavirus (BPV) infection. While multiple infections with human papillomavirus (HPV) are common in healthy and immunodeficient humans, studies with the aim of identifying mixed infections are still sporadic in veterinary medicine. The aim of this study is to describe the occurrence of multiple BPV infections in cattle affected by cutaneous papillomatosis. Fifteen skin warts were collected from at least two diverse anatomical regions of six bovines with papillomatosis belonging to three cattle herds from the Paraná state in Brazil. The BPV types present in the skin wart samples were determined by a PCR assay performed with the FAP primer pair for partial L1 gene amplification followed by direct sequencing or by cloning and sequencing of the inserts. Sequence analysis of the obtained amplicons allowed the identification of four characterized BPV types (BPV-1, -2, -6, and -8) and three previously described putative new BPV types (BPV/BR-UEL3, BPV/BR-UEL4, and BPV/BR-UEL5). Double infections were identified in four (A, B, D, and E) of the six animals included in this study. In this work, the strategy adopted to evaluate skin warts from diverse anatomical sites of the same animal allowed the identification of multiple infections with two or three different BPV types. The analysis of four animals belonging to a single cattle herd also showed the presence of six different viral types. These results clearly suggest that both multiple papillomaviral infection and a high viral diversity can be as frequent in cattle as in human beings.
