Resumo: Escherichia coli is a normal inhabitant of the enteric microflora of human and animal. Intestinal and extra-intestinal infections caused by E. coli in mammals are characterized by the presence of diversity of virulence factors. In addition it can be isolated from environment surrounding human and animal farms. E. coli is the main environmental pathogen causing clinical mastitis in dairy cattle. It causes a wide range of disease severity, from changes seen exclusively in milk to severe systemic signs. The severity of clinical mastitis has been conventionally classified into three levels: mild (grade 1), moderate (score 2), and severe (score 3). Recently, reports of cases of bovine mastitis caused by environmental agents have been on the rise, in particular in countries that have succeeded in controlling contagious microorganisms. Unlike enteric and certain extra-enteric conditions in domestic animals and humans, the impact of virulence factors on the occurrence of bovine mastitis due to E. coli, as well as the clinical severity of the cases, is not fully understood. In this regard, the present study reviewed the most relevant virulence factors of E. coli in human and animals, with emphasis in bovine mastitis.

As afecções entéricas e extra-entéricas causadas por E.coli em mamíferos são caracterizadas pela presença de ampla diversidade de fatores de virulência. Além disso, este micro-organismo também pode ser isolado em ambientes de produção animal. E. coli é o principal agente ambiental que causa mastite clínica em vacas leiteiras, provocando sinais clínicos que podem variar desde mudanças observadas exclusivamente no leite até sinais sistêmicos graves. A gravidade da mastite clínica é convencionalmente classificada em três níveis: leve (grau 1), moderada (grau 2), e grave (grau 3). Atualmente, os relatos de casos de mastite bovina causada por agentes ambientais têm aumentando, principalmente nos países que conseguiram controlar os micro-organismos contagiosos. Diferentemente de infecções entéricas e certas extra-entéricas em humanos e animais, o impacto dos fatores de virulência de E. coli na ocorrência de mastite bovina não é totalmente compreendido, assim como na gravidade clínica dos casos. Neste contexto, o presente estudo revisou os fatores de virulência de E. coli mais relevantes para humanos e animais, com ênfase na mastite bovina.UEL2019-07-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/otherapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3296310.5433/1679-0359.2019v40n5p2087Semina: Ciências Agrárias; Vol. 40 No. 5 (2019); 2087-2100Semina: Ciências Agrárias; v. 40 n. 5 (2019); 2087-21001679-03591676-546Xreponame:Semina.
