Virulence factors in Vibrios and Aeromonads isolated from seafood

M E Scoglio et al. New Microbiol. 2001 Jul.

Abstract

Thirty-one isolates from seafood, identified as Aeromonas hydrophila (7), Aeromonas caviae (11), Vibrio parahaemolyticus (3), Vibrio fluvialis (5), Vibrio alginolytictus (3), Vibrio metschnikovii (1) and Vibrio damsela (1), were tested for possible virulence factors including extracellular hydrolytic enzymes, haemolysins, cytotoxins (VERO and HEp-2 cells) and adherence ability (HEp-2 cells). All the A. hydrophila strains were beta-haemolytic and produced cytotoxins as well as one strain of V. fluvialis. A. hydrophila and A. caviae strains, frequently adhesive, showed both aggregative and diffusive patterns, while five Vibrio strains only (three V. fluvialis, one V. parahaemolyticus and one V. alginolyticus) were adhesive with an aggregative pattern.
