[Phage types of Vibrio cholerae and non agglutinable Vibrio isolated in Algeria from 1975 to 1977].

1 285 strains of Vibrio cholerae and 556 strains of non agglutinable Vibrio were isolated either from stool specimens or water in Algeria from 1975 to 1977. These strains were phage-typed with Basu and Mukerjee's 5 phages for the Vibrio biotype El Tor and with Mukerjee's phage IV for the Vibrio biotype cholerae. The results obtained are discussed in terms of choleraphages used for the diagnosis and epidemiological study of cholera.
