A Description of an Unusual Salmonella Type with Special Reference to the Evolution of Salmonella Species

Abstract

A new Salmonella type, S. salinatis, is described. The antigenic formula for this type is IV, XII . . . .: d, e, h[long dash]d, e, n, z15. Through cultivation of S. salinatis in semi-solid agar containing agglutinating serum for Eberthella typhosa, an organism having the antigenic formula, IV, XII . . . .:e, h[long dash]e, n, z15 was isolated. The latter is biochemically indistinguishable from the Sandiego type. The bearing of these observations, and of previous expts. on induced variation, on White''s theory of Salmonella phylogeny is discussed.
