AbstractBovine fibropapilloma and papilloma occur in different parts of the skin of animals. Bovine Papillomavirus (BPV) is an oncogenic virus making benign tumor lesion of together mucosal and cutaneous tissue in cattle. In order to confirm the clinical diagnosis; the study planned to make the molecular detection of BPV (DNA) using Polymerase Chain Reaction (PCR) from skin lesions and the phylogenetic analysis. Thirty-eight samples of skin lesions were collected from cattle clinically suspected to be infected with bovine papilloma virus from herds in Al-Qadisiyah Governorate in 2016, the primary clinical diagnosis depended on the morphological appearance and features of the lesion. Deoxyribonucleic Acid (DNA) was extracted from skin lesions; the DNA was examined by PCR technique using specific primer to BPV-1 /L gene-1. Twenty-two samples out of 38 (57,9%), which were collected from different regions in Al-Qadisiyah Governorate, were positive. The sequences of four positive samples of DNA product amplification of (BPV) type-1, L1 gene confirmed the PCR results. These samples had the DNA presented in four accession numbers KY662042-1, KY662043-1, KY662040-1 and KY662041-1. This study proofed that cutaneous bovine papillomatosis related with BPV-1 infection in the cattle herds has affinity to solid skin rather than other epithelial and mucosal tissue.
