It was shown by Edwards and Moran (Proc. Soc. Exp. Biol, and Med., 66, 1947, 230) that Salmonella sp. (Type Senftenberg) and Salmonella sp. (Type Simsbury) each could be transformed into the other. Bruner and Edwards (Jour. Bact., 55, 1948, 449) found that in certain instances antigen 3, 10 could be changed to antigen 3, 15 and again reversed to 3, 10. Bruner (Jour. Bact., 57, 1949, 387) obtained typical cultures of Salmonella sp. (Type (Oranienburg) from certain strains of Salmonella sp. (Type Montevideo). These antigenic changes, all of which were produced by induced variation, are of great interest and un- doubtedly throw light on phylogeny and evolution within the group. Further, it is highly probable that such changes occur in nature. However, the epidemiological significance of the various Salmonella types is well established, and observations such as those cited above in no way detract from the value of antigenic typing in the study of the epidemiology of Salmonella infections. For this reason the types are listed in the schema as they are found in nature. No antigenic relationship exists between the H antigens Zi, z-i , z^ , etc. The symbol z affixed by the numeral was chosen to denote these antigens, as no other letters of the al- phabet were available.
