Three strains, namely the K+ and K- (Kanagawa positive and negative) strains of. V. parahae-molyticus and a strain of V. alginolyticus were used to study the varation of flagellar morphology in different cultural conditions. All three strains showed M-(monotrichous) flagella in liquid media in different studies. But on solid media, the flagellar morphology varied depending on the type of meadia, levels of pH, NaCl concentrations, growth temperatures and other cultural conditions. Examination of flagella during the growth period of the statins revealed that V. alginolyticus and K+ strain of V. parahaemolyticus fist showed PM-flagella and then changed to P-(peritrichous) flagella, whereas K-strain showed P-flagella throughtout the growth period. The strains developed M-flagella when they were grown on TS3% NaCl medium containing gelatin (7%) and agar (0.75%) as solidigying agents. However, the same strains showed either mixed type or P-flagella when they were grown on ZoBell 2216E medium made with either different concentrations of agar of carrageenan. It was observed that the relation between swarming and P-flagellation depended on cultural conditions. The results obtained in the present study indicate the need for standardization of cutural conditions when estabishing flagellar morphology.
