“…Natural transmission of disease occurs through direct or indirect contact with infected animals (Kummeneje and Krogsrud, 1979) particularly with dried crusts that falls on the pastures during grazing (Harriss, 1948). The disease was also transmitted from wild to domestic goats when infected herds had prolonged contact with areas where salt blocks were provided artificially on highways and camp grounds.…”

| Contagious pustular dermatitis (CPD), also known as Orf or contagious ecthyma is an important viral disease of sheep and goats. It is mainly seen as a benign disease but malignant form has also been reported from few parts of the world. The rates of morbidity and mortality are higher, particularly in lambs and kids experiencing the disease for the first time. The causative agent of disease is Orf virus, type species of the genus Parapoxvirus belonging to family Poxviridae. The virus produces localized persistent proliferative skin lesions and affected hosts are infected repeatedly owing to its host immune evasive strategy. These viruses have been found uniformly labile to chloroform but resistant to ether and also exhibit antigenic variations among them. Clinically, the disease is enzootic and occurs in three forms viz. labial, genital / mammary and generalized forms. The incubation period in natural cases is 2-3 weeks. The disease outbreaks mostly occur between autumn and spring but its severity is more in autumn and winter than spring. The virus grows well in cell cultures of caprine, ovine and bovine origin. Confounding symptoms impose laboratory affirmation by serological assays or molecular techniques. The disease can be diagnosed by electron microscopy, serological tests and PCR/ quantitative real-time PCR. Virus specific antibody response to structural proteins of capripox and orf viruses in western-blot analysis readily differentiates these two infections. The antibody response to the 32 kDa and 26 kDa proteins of capripox viruses provides a firm basis for differentiation. Although, the role of humoral immunity is well established but probably cell mediated immunity plays a major role in recovery from natural infections. A number of inactivated and live or live modified vaccines have been tried with variable success. The duration of immunity after vaccination is controversial; outbreaks have occurred in vaccinated animals. The disease is also of public health significance as it causes infection in human beings.

“…Although the lesions described above grossly resemble strawberry footrot, so far we have not been able to detect either of the causative organisms ( Dermatophilus congolensis or Parapox virus). Strawberry footrot does not commonly cause marked lameness (Harris 1948). In conclusion, the aetiology of the lesions is presently unclear, although the response to systemic tilmicosin suggests a Gram‐positive bacterial infection, either primary or secondary.…”

“…Crusts exposed to external conditions lost their infectivity quickly during summer, but infectivity persisted for at least 6 months during winter (Boughton and Hardy, 1935). The disease may be caused by direct or indirect contact with the infected animals especially with dried crusts fallen on the pastures during grazing (Harriss, 1948;Kummeneje and Krogsrud, 1979). The disease was also transmitted from wild to domestic goats when infected herds had prolonged contact with salt blocks in the mutual habitat.…”

Orf virus occurs where sheep and goats are raised, and it also infects a broad range of wild artiodactyls. The rates of morbidity and mortality are higher, particularly in lambs and kids experiencing the disease for the first time. Orf virus has been reported in domestic animals and humans in Turkey, so far. In this study, findings on the presence of Orf virus on wild goats were researched for the first time. Field studies were carried out between 2016 and 2017 years. Direct observation methods were used in field studies. In this study, a dead six months of age male wild goat (Capra aegagrus) and 3 diseased individuals in poor condition with bloody lesions covering the muzzle area were examined in Sarıçiçek Mountain in Eastern Black Sea Region, Turkey. The gross and microscopic lesions confirmed the diagnosis of contagious ecthyma (CE). This is the first documented report of CE in wild goat from Turkey.
