A Histopathological, Immunohistochemical and Molecular Study of Cutaneous Bovine Papillomatosis

Abstract

In animals and man, some forms of cutaneous papillomas are caused by papillomaviruses. Twelve different genotypes of bovine papillomavirus (BPV) have been identified. BPV-1 through BPV-12 are all strictly species-specific. BPV-1 and BPV-2 are associated with fibropapillomas in cattle; these tumors are formed by excessive proliferation of virus-infected dermal fibroblasts and epidermal keratinocytes. In the present study well known diagnostic procedures including histopathological, immunohistochemical and molecular methods were used for the diagnosis of bovine papillomavirus infection.Samples were taken randomly from five cattle with multiple cutaneous tumor formations for the diagnosis of bovine papillomavirus infection occurring commonly in herds.In the present study five cattle were examined for the presence of multiple cutaneous tumors. Cutaneous fibropapillonnatosis were confirmed histopathologically and immunohistochemically. BPV-1 and BPV-2 which are etiological agents for the bovine cutaneous fibropapillomatosis were investigated by PCR. BPV serotyping was performed from five cattle all coming from three different farms. In conclusion papillomaviral DNA was detected by the PCR. The amplified long control region (LCR) DNA sequence was identical to that of BPV-1 and negative for the BPV-2 DNA. When considered economical impact of the disease associated with the abundance of the infection significance of protective measures and vaccine studies come forward.
