Determinou-se a prevalência dos genes de virulência expressando fimbrias, produção de hemolisina, colicina e aerobactina em cepas de Escherichia coli obtidas do trato genital de vacas saudáveis que não apresentam sinais clínicos indicativos de infecção. A presença dos genes responsáveis pela expressão de fimbrias (pap, sfa, afa) foi avaliada através de reação em cadeia da polimerase utilizando primers especificos para cada um dos genes, nenhum deles foi detectado em qualquer uma das cepas isoladas. A prevalência dos fatores de virulência foi de 90,4%, 69,8%, 28,5% para colicina, hemolisina e aerobactina, respectivamente. A análise da patogenicidade das cepas do trato genital pode contribuir para o entendimento do comportamento das cepas de ...
