Salmonella 38:g,z51:-, a new Salmonella of sub-genus IV: a serological study on the complex H-antigen g,z51 which can be divided into three sub-genus specific factors.

A new Salmonella of sub-genus IV with the antigen formula 38:g,z51:- has been isolated from a boa. Comparative studies of the H:g,z51 revealed that this phase only occurs in the sub-genera I, III and IV but not in sub-genus II. Furthermore it became evident that there exist typical serological differences between the g,z51 phases of Salmonella sub-genus I, III and IV which are of significance for the differential diagnosis.
