Out of 101 staphylococcus strains isolated from pus, healthy carriers, or from dust, 12 strains produced enterotoxin when tested in the chick embryo test of Kienitz and Preuner. Ten of these strains were phages of lysogenic group III. Lysogenic group I predominated among the staphylococci incapable of producing enterotoxin. Seven enterotoxic strains were isolated from healthy carriers and dust.
