Stool cultures from 58 cases of acute bacillary dysentery occurring in Dallas, Texas, in the summer of 1933, yielded 26 cultures of dysentery bacilli. Sixteen of these were identified as Shigella paradysenteriae var. Flexner, five as Shigella dispar Andrewes, and five as Shigella paradysenteriae var. Sonne. Relative inagglutinability of the Sonne types was observed.
