[The antimicrobial sensitivity and plasmid isolation in Plesiomonas shigelloides]. / Susceptibilidad antimicrobiana y aislamiento de plásmidos en Plesiomonas shigelloides.

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.
