Vibrio anguillarum kills various kinds of fish over salinities ranging from seawater to freshwater. In this study, we investigated the role of Na+in V. anguillarum, especially under energy-depleted conditions such as in natural seawater. V. angustum S14, which is a typical marine vibrio, was used for comparison. V. anguillarum only required Na+for starvation-survival, but in contrast, V. angustum S14 always required Na+for both growth and starvation-survival. In marine vibrios, Na+is used in the Na+-dependent respiratory chain that produces the sodium motive force (SMF) across the cell membrane. It has been considered that marine vibrios always need a SMF produced by Na+, however in the case of V. anguillarum, the SMF is not required for growth, but becomes more important for starvation-survival. © 2004 Federation of European Microbiological Societies.
