Nos últimos anos houve um aumento considerável no rebanho de caprinos e ovinos no Brasil, sendo a região
Nordeste onde se concentram os maiores rebanhos desses animais. Apesar da importância econômica e cultural, a
cadeia produtiva ainda enfrenta enormes desafios sanitários. Dentre as doenças infecciosas que acometem os
rebanhos dos pequenos ruminantes, o ectima contagioso, boqueira ou dermatite pustular labial, como também é
conhecida, está entre as de maior importância, devido a sua apresentação em forma de surtos, causando grandes
prejuízos econômicos e afetando a rentabilidade dos produtores. O ectima contagioso é uma doença infecciosa
viral causada por um vírus, do gênero Parapoxvirus, pertencentes à família Poxviridae, que acomete caprinos e
ovinos de todas as idades, e com alta morbidade, podendo se apresentar em 100% do rebanho, durantes os surtos.
É mais prevalente em animais jovens, afeta o desempenho produtivo, causa a perda de peso, podendo levar ao
óbito após complicações. Nesta revisão abordaremos sua etiopatogenia, as novas perspectivas de diagnóstico,
tratamentos e profilaxia, e sobretudo a possibilidade do desenvolvimento de novas vacinas mais eficazes, a fim de
14 diminuir a incidência e os prejuízos causados por essa afecção.
Palavras-chave: caprinocultura, dermatites, ORF vírus, ovinocultura, zoonose.
In recent years,there has been an exponential increase in the herd of goats and sheep in Brazil,with the Northeast
region being the largest producer of these animals.Despite its economic and cultural importance,the production
chain still faces enormous health challenges.Among the infectious diseases that affect herds of small ruminants,
the contagious ecthyma,mouth or labial pustular dermatitis, as it is also known,is among the most important due
to its presentation in the form of outbreaks, causing significant economic and productive losses, affecting the
profitability of producers. Contagious ecthyma is an infectious viral disease caused by a virus of the genus
Parapoxvirus,belonging to the Poxviridae family,which affects goats and sheep of all ages and with high morbidity. It can occur in 100% of the herd during outbreaks.It is more prevalent in young animals, affects productive
performance,causes weight loss,and can lead to death.is review will address its etiopathogenesis,new perspectives for diagnosis,treatments, and prophylaxis, and the possibility of developing new, more effective vaccines to
reduce the incidence and damage caused by this condition.
