    Abstract

    Vibriosis in shrimp culture causes about 80% mortality. In the present study. Vibrio isolated from diseased Penaeus monodon was characterized as Vibrio alginolyticus. The physical, cultural and biochemical investigations carried out in the study confirmed the isolate. Growth of V.alginolyticus in Zobell marine broth indicated no lag period, while the peak growth was observed at 18 hours. V.alginolyticus was found to cause mortality in healthy shrimps in artificial infection studies. One hundred percent mortality was noted at 5.7x10 cells, 5.7x10 cells, 5.7x10 cells per P.monodon. Reisolation studies indicated the presence of the same bacteria in haemolymph and other body tissues.
