P. 5612-5614The hemolytic activity and siderophore production of several strains of motile aeromonads were determined.
The hemolytic activity of Aeromonas caviae and Aeromonas eucrenophila was enhanced after trypsinization of the
samples. The enhancement of hemolysis was observed in strains that carried an aerolysin-like gene, detected
by a PCR procedure. Siderophore production was demonstrated in all but one strain of Aeromonas jandaei. No
apparent relationship was observed between the presence of plasmid DNA and hemolysis or siderophore
production.S
