Se estudiaron 30 cepas de Plesiomonas shigelloides aisladas de pacientes con enfermedad diarreica aguda y procedentes de los diferentes centros de salud del país. Se caracterizaron fenotípicamente mediante pruebas bioquímicas convencionales y se les determinó la susceptibilidad antimicrobiana por el método de Kirby Bauer, frente a 11 drogas. Se halló que las cepas de Plesiomonas shigelloides fueron sensibles a 7 y resistentes a 6 de las drogas investigadas. Se determinó la presencia de plásmidos en 12 de 29 cepas analizadas y se evidenció la diversidad en sus patrones plasmídicos.

30 strains of Plesiomonas shigelloides isolated from patients with acute diarrheal disease at different health centers of the country were studied. The were phenotypically characterized by conventional biochemical tests and the antimicrobial susceptibility to 11 drugs was determined by the Kirby Bauer’s method. It was found that the strains of Plesiomonas shigelloides were sensitive to 7 and resistant to 6 of the investigated drugs. The presence of plasmids in 12 of the 29 analyzed strains was determined and the diversity in their plasmidic patterns was proved.
