- Abstract
In a microbiological monitoring carried out in various aquatic environment of Sardinia Island (Italy) Vibrio alginolyticus with different virulence phenotypes appeared widely spread. Hemolysis, hemoagglutination and protease production might be together particularly in strains isolated from polluted environments. Adherence capacities to two epithelial cells (Hep-2 and Caco-2) available in laboratory were widely spread in the examined bacterial strains. The adhesion degree was influenced by the utilized cellular clone. The lack of a correspondence between adhesion capacity and more traditional virulence tests do not permit its replacement at screening level.
