Abstract   

    Cutaneous papillomatosis is usually regarded as benign epithelial tumor caused by pipalioma virus. The condition is species specific and has the tendency to spread frequently. In this study, a total of 15 horses suffered from cutaneous papalloma were used to study the efficacy of the autogeneous papilloma vaccine. Each horse was examined clinically and few wart lesions were removed surgically and divided into two portions. One portion was fixed in 10% butTered neutral formaline for histopathological studies. The second portion was submitted for autogenous papilloma vaccine preparation. A total of 13 horses proved to be infected with cutaneous papilloma received three doses of 0.5 ml on weekly intervals intradermally. Two other horses with cutanesous pappillama were left with no vaccine to serve as control. Results indicated that all horses received the vaccine were free from papilloma lesions 3-5 weeks following the last dose of the vaccine whereas the control groups remained infected
