Genomic diversity among 34 strains of Escherichia coli belonging to different serotypes of the O26 serogroup – encompassing strains from different geographical origins and Shiga toxin-negative Brazilian strains – was evaluated through random amplified polymorphic DNA (RAPD) analysis. Our results indicate that Brazilian and non-Brazilian O26 strains fall under distinct but closely related differentiation clusters. RFLP-PCR analysis of the fliC gene sequence was done in order to identify the H− serotypes and served to confirm the clustering pattern obtained in the dendrogram generated from RAPD data. The epidemiological significance of these data is discussed. |
