In this study a common antigenic factor (s) between C. albicans CBS-562 and S. cholerae suis 211 (0:6(2),7) was shown with agglutination and absorption tests. This common antigenic factor (s) is different than previously shown Salmonella 0:7 antigen. This new factor (s) is not present in S. cholerae suis var. kunzendorf 1350 (0:6(1), 7) and S. cholerae suis var. kunzendorf 5210 (0:6(2),7) serotypes.
