ABSTRACT
Pathogenic Vibrio cholerae isolates, the etiologic agents of cholera, generally express one of two O antigens (O1 or O139). Most environmental isolates are nonpathogenic and are referred to as "non-O1, non-O139". However some V. cholerae non-O1, non-O139 strains are clearly pathogenic and have caused outbreaks or sporadic cases of gastroenteritis and extraintestinal infections in humans. We report a case of acute gastroenteritis by a V. cholerae non-O1, non-O139 harboring a genetic region homologous to a segment of the VpaI-7 V. parahaemolyticus pathogenicity island.
RESUMEN
Cepas patogénicas de Vibrio cholerae, el agente causal del cólera, expresan generalmente uno de dos antígenos O (denominados O1 u O139). La mayoría de las cepas ambientales son no patogénicas y corresponden al tipo denominado "no-O1, no-O139". Sin embargo, algunas cepas de este tipo son claramente patogénas y han causado brotes de gastroenteritis e infecciones extra-intestinales en humanos. Se reporta un caso clínico de gastroenteritis aguda causado por una cepa de V. cholerae no-O1, no-O139 que contiene en su genoma una región homóloga a un segmento de la isla de patogenicidad VpaI-7 descrita previamente en V. parahaemolyticus.
