Diarrhoeic shellfish toxins in Adriatic Sea mussels evaluated by an ELISA method.

A competitive enzyme immunoassay (ELISA) was used to determine the presence of okadaic acid (OA) and/or dinophysistoxin-1 (DTX-1) in mussels. The accuracy and sensitivity of the ELISA method has been checked. The sensitivity of the method (100 ng/g of hepatopancreas) makes it possible to determine OA concentrations ten times lower than the tolerance limits established by the Health Authorities of many countries. For the first time, OA and/or DTX-1 were detected in mussels (Mytilus galloprovincialis) collected in different stations along the Adriatic Sea coasts.

Virulence factors in Vibrio alginolyticus strains isolated from aquatic environments.

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.
