Abstract
API-ZYM system and antibiotic sensitivity assay were used to characterize twelve
strains of Vibrio and three strains of Aeromonas, each belonging to different species. APIZYM
showed that all tested strains exhibited negative activity for a-galactosidase,
P-glucuronidase, a-mannosidase and cc-flucosidase. All strains expressed positive activities
for alkaline phosphatase, esterase (C4), esterase lipase (C8), leucine arylamidase, acid
phosphatase, and naphthol AS-BI phosphohydrdase. p-glucosidase activity was a
characteristic of the three Aeromonas strains. Also, Aeromonas strains as well as V. damsela
gave very high N-acetyl P-glucosamidase activities. Aeromonas hydrophila, A. trota and V.
hollisae were susceptible to all 9 tested antibiotics, and ClO and C30 were active against
all tested strains. API-ZYM system and antibiotic susceptibility profile gave additional
information that can help in identifying and separating very close species of Vibrio and
Aeromonas.
