Abstract

Lethal toxin was purified extensively from the culture filtrate of a Kanagawa phenomenon-positive strain of Vibrio parahaemolyticus. The purified toxin was a protein, and its homogeneity was demonstrated by sodium dodecyl sulfate-polyacrylamide gel disc electrophoresis and analytical ultracentrifugation. It was demonstrated that the thermostable direct hemolysin was identical to the lethal toxin and that it was the main, if not only, lethal toxin in the culture filtrate. The purified toxin had a lethal effect when injected into mice either intravenously or intraperitoneally. Its lethal effect was very rapid, a dose of 5 mug of toxin per mouse killing the animals within 1 min. The lethal activity was inhibited by a ganglioside mixture. Some physicochemical properties of the purified toxin are reported.
