Abstract

A thermolabile toxin (molecular weight, 52 711; isoelectric point, 8.65) produced by a clinical isolate of Vibrio cholerae serogroup non-O1 was cytotoxic for Y-1 mouse adrenal cells and Chinese hamster ovary cells. The toxin lysed rabbit red blood cells and produced a hemorrhagic zone in rabbit skin. When injected intravenously into adult mice, the cytolysin was rapidly lethal and caused fluid accumulation in both 5- and 18-h rabbit ileal loops. Strains of V. cholerae that produced cytolysin but no cholerae enterotoxin were able to cause fluid accumulation in rabbit intestinal loops.
