1. The presence of a new thermolabile an named β antigen has been demonstrated in motile and non-motile coliform, paracolon and Proteus strains, and in Shigella bacilli (Sh. flexneri Sh. flexneri V1 and D19). This antigen can be frequently found in the above types.

2. The characteristics of the β antigen have been described, and its dissimilarity to H, O, Vi, 2, A, B and α antigens has been established.

3. A high incidence of β antibodies was demonstrated in normal human and rabbit sera.

4. β strains of paracolon and coliform b injected intraperitoneally into mice were shown to be more virulent to mice than β minus forms of the same strains.

5. It is suggested that unrecognized presence of β antigen in cultures and β antibody in human and rabbit sera may cause errors in bacteriological and serological diagnoses of enteric infections.
