STUDIES ON THE ENTEROBACTERIA HAVING ANTIGENS OF SALMONELLA G GROUP

I. ANTIGENIC RELATIONSHIP BETWEEN ORIGINAL AND TEST STRAINS OF SALMONELLA, ARIZONA AND ESCHERICHIA

Abstract

Antigenic analysis of Salmonella G group, arizona O-18, E. coli O-86, E. coli O-127a, b O-127a.c and E. coli O-128 indicated as follows;
1) These strains have an antigen concerning with Salmonella O-13 and the latter is composed of 6 or more partial antigens.
2) In the relationship of E. coli O-127a and O-128, specific antigen of. E. coli O-127a is involved as well as Sal. O-13.
3) E. coli O-127 has antigens of Sal. O-13 and 22. Antigenic relationship between the substrains is not a-a, b, which is noted by Ewing. but a, b-a, c.
4) Isolated strains having antigens of G group Salmonella are classified in many genera ; 4 strains are E. coli of which 2 are E. coli O-127a, c and the other 2 are E. coli O-86. Three strains are E. freundii. The one has complete antigen of E. coli O-127a, c, another has partial antigen of Sal. O-13, 37 and specific antigen of O-127a and O-128 and the last one has partial antigen of Sal. O-13 and 37.
