Molecular and phenotypic characterization of Shigella sonnei isolated over 31 years suggest the circulation of two prevalent subtypes in the São Paulo State in Brazil.

In conclusion, the pathogenic potential of the strains studied was highlighted by the presence of important virulence genes. The high rates of resistance to trimethoprim-sulfamethoxazole and tetracycline are alarming once those drugs can be used in the treatment of shigellosis. The PFGE and ERIC-PCR results suggest that there are two prevalent subtypes in the S. sonnei strains studied that differed little over 31 years and have been contaminating humans and causing diseases in the São Paulo State-Brazil.
