Biotyping, serotyping and genotyping of aeromonads from environmental and clinical samples

Pulsed-field gel electrophoresis (PFGE) and biochemical-serological assays were used to characterize environmental and clinical aeromonads. On the bas is of their biochemical characteristics, 31 strains were assigned to one of the recognized groups or species within the Aeromonas genus and 11 differe nt serogroups were detected. Low correlation between molecular and traditio nal typing methods was observed. The results obtained showed that the genom ic analysis performed by PFGE can be a more effective means for distinguish ing between Aeromonas isolates than conventional biochemical methods.
