Phenotypic characteristics of 100 strains pertaining to the group of mesophilic aeromonas isolated in feces of patients with diarrhea (23 A. hydrophila, 34 A. sobria, 19 A. caviae, and 24 considered atypical because produced a the negative esculin reaction and a positive gas formation from glucose [TSI]). The percentages obtained in the different biochemical tests support the hypothesis that in this group there is a taxonomic complexity. We observed variations in the following tests: LDC, arabinose, Voges-Proskauser, lactose, and motility and hemolytic activity. We compared manual and automatic procedures in detecting esculinase and beta-galactosidase activity (ONPG). The study of constitutional enzymatic activity by means of API ZYM system can not be used to differentiate the distinct species although the enzyme beta-glucosidase is detected preferentially in A. hydrophila.
