Marine Vibrio sp. cells swarmed on the highly viscous surface of a medium containing 1.5 ％ agar and various concentrations of NaCl up to 1.2 M. The peak value of the swarming speed was 0.83 ± 0.13 μm s-1 at 0.5 M NaCl, while the values of the doubling time showed a broad peak of 0.34 to 0.35 h in the range of 0.3 to 0.6 M NaCl. Swarming motility was completely repressed in the presence of 2 mM amiloride. These results indicate that the lateral flagella motor proteins of the isolate might have reduced the selectivity for the cation species.
