Resumo
Foram estudadas 103 cepas de Escherichia coli do sorogrupo O128, quanto às características fenotípicas e genotípicas associadas à virulência. Cinqüenta e nove cepas representantes de todos os sorotipos foram submetidas a ribotipagem. Os sorotipos mais freqüentes foram O128:H35 (41,7%), O128:H2 (14,6%), O128:H- (8,7%) e O128:H8 (6,8%). Diferentes grupos enteropatogênicos foram identificados. Somente as cepas do sorotipo O128:H2 foram positivas para as sondas eae and bfpA e apresentaram o padrão de adesão AL-like. Cepas do sorotipo O128:H8 e algumas imóveis reagiram apenas com a sonda eae e foram classificadas como EPEC atípicas. As cepas O128:H35 corresponderam à categoria enteroagregativa e os sorotipos O128:H7, O128:H21, O128:H27 e as cepas imóveis foram classificadas como enterotoxigênicas. Todas as cepas que apresentaram marcadores de virulência pertenciam ao grupo clonal A, enquanto que no grupo clonal B estavam incluídas as cepas desprovidas dos fatores de virulência pesquisados.Referências
