ABSTRACT
Amostras uropatogênicas de Escherichia coli isoladas de indivíduos moradores de localidades distintas na Cidade do Rio de Janeiro, foram caracterizadas quanto o sorotipo, propriedades hemolíticas e hemaglutinantes, susceptibilidade a antimicrobianos e perfil isoenzimático. O método molecular empregado associado com a investigação de marcadores de urovirulência, permitiu detectar uma grande diversidade entre os isolados. Entretanto, foi observada uma relação mais estreita entre amostras de Escherichia coli epidemiologicamente relacionadas.
Uropathogenic Escherichia coli strains isolated from individuals living in different areas of the city of Rio de Janeiro were characterized according to serotype, hemolytic properties, hemagglutination properties, antimicrobial susceptibility and isoenzymatic profile. The molecular approach used, together with investigation of urovirulence markers, enabled detection of great diversity among the isolates. However, closer relationships were observed between epidemiologically related Escherichia coli samples.
