The description of Salmonella anatum

sents the first characterization of any of the bacilli now included in group E of the genus Salmonella. White (1926) de-scribed Salmonella london but it was not until 1932 that Lovell suggested that the two types belonged to the same group. Kauffmann and Mitsui (1930) demonstrated a partial relationship in the somatic antigens of 8. london and Salmonella senftenoerg. The antigenic constitution of 8. anatum was estab-lished by Kauffmann and Silberstein (1934) who simultaneously described a closely related type now designated as Salmonella muenster. It was later found by Edwards (1935, 1937) that certain cultures previously classified as 8. anatum possessed distinct somatic antigens. Such cultures are now classi-fied as Salmonella newington. Subse-quently a number of new types were recognized and, in the report of the Salmonella Subcommittee (1940), thir-teen types were included in group E. These types and their antigenic formulae are given in table 1. To this list must now be added Sal-monella lexington of Edwards, Bruner and Rubin (1940), the antigenic formul
