Abstract
- This study characterized the phenotypic and genetic properties of Vibrio spp. and Aeromonashydrophila strains isolated from seawater and mussels (Mytilusedulis and Crassostreagigas) cultured in mollusc farm localized in the lac of Bizerte. The 37 strains (31 strains of V.alginolyticus, one strain of V. fluvialis, one strain of V. parahaemolyticus and four strains of A.hydrophila) typed by enterobacterial repetitive intergenic consensus PCR (ERIC-PCR) showed a high polymorphism. Most of the isolates were resistant to at least two antimicrobial agents. All the tested strains were resistant to ampicillin. PCR was used to detect the presence of eight Vibriocholerae virulence genes in the genome of the Vibrio spp. isolates. The results showed a wide dissemination of these genes in the genome of all Vibrio spp. isolates tested. Differentiation of these strains with the ERIC 2-PCR technique revealed no association between the presence of virulence genes and a particular fingerprinting pattern.
