Abstract
Sensitivity to the O-1 phage was tested on 5287 Salmonella strains isolated in the course of routine diagnostic work over the period 1971-1973. Of these, 3380 (99.2%) B group strains, 676 (97.8%) C group, 840 (98.8%) D group and 195 (83.0%) E group strains were sensitive to the O-1 phage. Of the 5287 strains, 92 belonged to other O-groups in the Kauffmann-White scheme; 91.3% of these were phage-positive; 5274 of the strains belonged to subgenus I and only 100 of them were not sensitive to the O-1 phage. A total of 13 strains belonged to subgenera II, III and IV. The O-1 phage was considered to be suitable for the identification of Salmonella bacteria. Monophasic strains belonging to subgenus III and strains belonging to subgenus IV are usually not sensitive to the O-1 phage. Of the total number of strains, 98.0% were sensitive to the O-1 phage.
