RESUMEN
Orf o Ectima contagioso, enfermedad producida por virus DNA perteneciente a la familia poxviridae género parapoxvirus; se caracteriza por producir enfermedad vesicular en ganado, principalmente en rumiante menores. Personas que tengan contacto con animales u objetos contaminados con el virus pueden desarrollar la enfermedad, la cual es catalogada como la zoonosis de mayor diagnóstico en países donde la industria ovina se desarrolla a gran escala. Las lesiones más comunes se ubican en la zona bucal y ventanas nasales de animales y en dedos y manos en ser humano. En Chile existe la enfermedad y se han reportado casos en personas relacionadas a la industria ovina. No existe en el país método de diagnóstico, por lo cual se estandarizó una prueba de diagnóstico molecular (PCR) a partir de un oligonucleótido sintetizado y posteriormente se reprodujo la técnica a partir de un especimen biológico clínicamente positivo.
ABSTRACT
Orf or contagious Ectima, a disease produced by virus DNA belonging to the family poxviridae genus parapoxvirus is characterized by generating vesicular disease in cattle, specially in minor ruminants. Persons having contact with virus contaminated animals or objects might develop the disease, which is classified as the most frequently diagnosed zoonosis in countries where the sheep industry is developed on large scale. Most common lesions are located in the mouth zone and nasal windows of animals and in fingers and hands in the human being. The disease is present in Chile and cases related to persons working in the sheep industry have been reported. There is not a diagnosis method in the country, for which reason a molecular diagnosis test (PCR) was standardized from a synthesized oligonucleotid and subsequently the technique was reproduced from a clinically positive biological specimen.
