Abstract
Genetic variation of 33 enteroinvasive Escherichia coli (EIEC), 12 non-EIEC and 39 Shigella strains (representing the 4 species of this genus) was analyzed using the random amplified polymorphic DNA (RAPD) technique. Reproducible polymorphisms were generated and the combined data allowed us to construct a dendrogram using Jaccard's distance. Two main groups were obtained: one for Shigella and the other for EIEC and non-EIEC strains. The first group contained four clusters, one for each Shigella species. The second group contained one cluster for EIEC and another for non-EIEC strains. The main clusters encompassed many small clusters corresponding to different serotypes. It was possible to characterize each one of the 84 strains under study as well as the boundaries among Shigella species and between this genus and EIEC strains.Entities:
