Abstract

Biochemical, pathogenical, antigenical, and molecular characteristics of Vibrio alginolyticus iso- lates from diseased cultured gilthead sea bream juveniles (4 and 20 g) were determined by lab- oratory challenge experiments. Intraperitonal challenge resulted in development of the disease but immersion did not. Electrophoresis of outer membrane protein (OMP) and lipopolysaccha- rides (LPS) was performed using sodium dodecyl sulphate poly-acrylamide gel electrophoresis (SDS-PAGE). Molecular typing of Vibrio isolates was conducted using random amplification of polymorphic DNA (RAPD). According to SDS-PAGE of surface antigens of the isolates, profiles of both OMP and LPS were heterogeneous. According to RAPD, isolated bacteria varied genet- ically. The findings reveal differences among V. alginolyticus isolates from diseased cultured gilt- head sea bream in Turkey.
