| Resumo: | The contagious ecthyma is a disease caused by Orf virus, which induces acute skin pustules lesions in sheep and goats. In Brazil the frequency of Orf virus infection seems to be higher than that officially reported. This study is the first report on the Orf virus identification and laboratory confirmation in herds of goats in Bahia. The State Agency of Agriculture Defense of Bahia reported the occurrence of an epithelial disease in goats of Canindé and British Alpine breeds in the Barreira and Pedra alta localities. The lesions were characterized by the occurrence of scabs around the labial fold or being restricted to the udders. The samples from lesions scab were collected from goats labial fold and teats. DNA samples were extracted from these materials, and analyzed by polymerase chain reaction (PCR), and the genes ORFV 011 (B2L, 1022 base pairs [bp]) and ORFV 059 (F1L, 1062 bp) were amplified. All of the samples showed positive PCR reaction, confirming the Orf virus infection in the goat herds of Bahia state. |
