Standard bacteriological methods were followed in typing the specific cholera vibrio causing the then-current epidemic in Calcutta. Stool cultures were taken by rectal swab, streaked out on bile-salt agar plates, and incubated for 12 hours. The cholerastrains were then typed by the agglutination method. Rabbits were used to produce the specific agglutinating sera. Ninety-five percent of the vibrio present in this epidemic were the Ogawa strain, three percent were the Inaba strain, and two percent were not agglutinable.
