Clinico‐histopathological and molecular detection of small ruminants’ papillomaviruses in Iran
2024
Overview
Background Papilloma DNA viruses are one of the viruses that cause skin lesions in ruminants. Objectives The clinical, histopathological and molecular characteristics of cutaneous papilloma in ruminants in Iran are to be investigated in this study. Methods Samples were collected from 19 small ruminants (5 sheep and 14 goats) with various papillomatosis lesions. The samples taken were studied with histopathological and molecular techniques. Results In clinical terms, the lesions appeared in different sizes, ranging from 0.5 to 11 cm, and the cauliflower exophytic masses appeared in other parts of the animal's body. In the limbs, most papilloma lesions have been seen (42.1%). In histopathological examination, perinuclear vacuolation epidermal granule layer with various degrees of hypergranulosis, hyperkeratosis, acanthosis, orthokeratosis and parakeratosis were seen. Moreover, all the suspected samples were positive for papillomavirus using the polymerase chain reaction technique. Conclusions Although the prevalence of papillomaviruses in Iranian sheep and goats is low, it seems necessary to distinguish them from other viral skin diseases, such as cutaneous contagious ecthyma, using molecular techniques and histopathology. In this study, sheep and goats with clinical signs of papillomatosis were identified. Sampling was done from them. The samples were sent for further laboratory tests. Clinical examinations, molecular PCR tests, and histopathological examinations confirmed the presence of papillomavirus. This is the first study of papillomatosis in sheep and goats in Iran.
