We measured the cytotoxic activity of 119 strains ofShigellaby using a quantitative [3H]thymidine-labeled HeLa cell assay. We assayed 13 strains ofShigella dysenteriae1; 18 strains ofS. dysenteriaetypes 2 and 3; and 88 strains ofShigella sonnei,Shigella flexneri, andShigella boydii. Strains ofS. dysenteriae1 demonstrated high levels of cytotoxicity (geometric mean, 105.04CD50/mg of protein; range, 103.95–106.10). Cytotoxic activities of the non-type 1 strains ofS. dysenteriaeand of the otherShigellaserogroups were ∼1/1,000 that of theS. dysenteriae1 strains (range, 101.09–103.11CD50/mg of protein). Neutralization of cytotoxicity by using rabbit antiserum to purified Shiga toxin revealed that in all strains ofS. dysenteriae1, ⩾99.5% of cytotoxic activity was attributable to Shiga toxin. In contrast, 88 of the otherShigellastrains produced only nonneutralizable cytotoxic activity. Six of 18 strains of non-type 1S. dysenteriaeand 12 of 88 strains from otherShigellaserogroups produced both Shiga toxin and nonneutralizable toxin.
