The S. aureus 209P UF mutant dehydrogenase activity suppression method was used for detection of enterotoxin of Enterobacteriaceae opportunistic bacteria. Comparison of V. cholerae non 01, E coli and K. pneumonia toxigenic and nontoxigenic strains, neutralization test with antitoxic anticholera serum, comparative study of toxigenicities in paw edema test (according to Yu. P. Vartanyan) have shown that Escherichia and Klebsiella toxigenic strains can suppress S. aureus 209P UF mutant dehydrogenase activity, which fact permits the employment of this method for the detection of opportunistic bacteria enterotoxigenicity.
