Contagious ecthyma outbreak among goats at Nilgiri hills

Abstract

Contagious ecthyma is a highly contagious viral disease of sheep and goats, caused by Parapoxvirus. In the present outbreak over a range of 3 km radius in a hamlet near Ooty town in the Nilgiris hills, a total of 174 out of 194 non-descript goats were clinically affected with the symptoms of pyrexia (40°C), anorexia, depression, proliferative scab lesions on the skin around the mouth, oral commissures and nostrils. The morbidity rate was 89.7% without mortality. The symptoms were suggestive of contagious ecthyma. The disease was confirmed by agar gel immunodiffusion test, counter immunoelectrophoresis, and by polymerase chain reaction. Affected goats were treated with antibiotics, anti-pyretic, antiinflammatory and vitamin B complex injections parenterally. Commercially available herbal topical spray (Topicure®) and/or neem leaf and turmeric paste was applied to alleviate the skin lesions. Affected goats were recovered in 4 to 5 weeks. This paper reports the first incidence of contagious ecthyma outbreak in goats during rainy season of the year in high altitude (the Nilgiri hills), Tamil Nadu.

Whole-Genome Sequence of an Orf Virus Isolate Derived from a Cell Culture Infected with Contagious Ecthyma Vaccine

“…Contagious ecthyma is caused by the orf virus (ORFV), a member of the genus Parapoxvirus within the family Poxviridae that infects the skin and oral mucosa of ruminants, primarily sheep and goats, and causes painful vesicles, pustules, and proliferative lesions, typically around the mouth and nose ( 1 , 2 ). The morbidity rate is approximately 89% in sheep, and the disease has a substantial economic impact ( 1 , 3 ). The virus survives in scab material from ORFV lesions and can remain infectious for up to 15 years ( 4 , 5 ).…”

First report of contagious ecthyma (orf) outbreak in goats of Andaman and Nicobar Islands

“…The disease is prevalent in worldwide and morbidity is very high usually ranges from 70-85 % causing huge economic losses (Peralta et al, 2015). In India, this disease has been reported from many areas (Mondal et al, 2006;Balakrishnan et al, 2017), however, so far no outbreak or any confirmed cases of the orf has been reported from this Islands. In the present study detail study has been carried out to study the outbreak of orf during different season and confirmation by PCR assay.…”
