Molecular Characterization of the Presence of Bovine Papillomavirus in Cattle Teat Warts and a Different Treatment Approach

Background: Papillomatosis is a skin condition that is distinguished by benign proliferative tumors with a complicated etiology and epithelial proliferation. There is a need to perform a more thorough study on bovine papillomavirus and identify the virological properties of the agent in detail since a definitive treatment approach against this infection has not yet been completely identified and the suggested treatment outcomes differ. Methods: Samples were collected from warts developing on the teats of 500 cattle raised for milk production in Burdur Center and its districts. The samples were defrosted in order to extract DNA and the Dneasy Blood and Tissue Kit was used for the extraction procedure. By using a PCR assay, wart sample extracts were examined for 13 different BPV types (excluding BPV Type 7). For BPV type-specific primers, a protocol was utilized. Amplification products were demonstrated using agarose gel electrophoresis. Result: In the PCR test of 500 wart samples, BPV types (type 1-type 13) were detected in 378 (75.6%). In the general distribution of BPV types (single or mixed types) in teat warts, BPV-2 (n=85; 22.49%), BPV-8 (n=45; 11.90%), BPV-9 (n=48; 12.70%) and BPV-10 (n=52; 13.76%) were determined to be more common. In the study; it was determined that three different combined treatments provided 100% regression or complete recovery in warts developing on the teat of cattle. In conclusion; one of these three treatment combinations may be preferred for teat wart lesions in cattle.
