Caracterización fenotípica y factores de virulencia en cepas de Aeromonas aisladas de pacientes con enfermedad diarreica aguda en Cuba

fifty four strains of aeromonas spp were isolated from patients with acute diarrheic episodes by using aerokey ii and aeroesquema methods. in vitro antimicrobial susceptibility and virulence factors were analyzed. the most frequently isolated specie was aeromonas caviae. over 75% of strains exhibited resistance to penicillins and ce-phalosporins; for the other antibiotic groups resistance was under 20%. twenty six strains (48.1 %) were multiresist-ant. at least one virulence factor among those evaluated in the study was present in 53 (98.1%) of the 54 strains.
