abstract="We study the &quot;suicide&quot; phenomena as well as metabolic pathways of mixed acids (methyl red test, MR) and butylene glycol (Voges-Proskauer, VP), in 107 strains belonging to mesophilic Aeromonas group, isolated from stools. The strains have been identified as A. hydrophila, 28 cases (26.1%), A. sobria 26 cases (24.3%) and A. caviae 53 cases (49.6%). All A. caviae strains behave homogeneously as F+, RM+ and VP-, independently of temperature (30 or 37 degrees C). A. hydrophila strains only showed their trend to &quot;suicide&quot; at 37 degrees C, being this behavior linked to RM test positivity. At 30 degrees C all strains were NS and RM-, keeping always positive the VP test (both temperatures). In A. sobria we have recorded changes in their behavior related to the temperature of incubation. At 37 degrees C, 57.7% were NS, whereas at 30 degrees C, 69.2% showed the same phenotype. The metabolic activity had remained stable, therefore F+ strains were VP and RM+, and NS strains were VP+ and RM-. It seems that FS is a phenotypic behavior of this bacterial group species and temperature-dependent, and also is related to a fermentative metabolic activity modulation of each of them.<p /><p>Language: es</p>",
