Abstract:
Of the 34 strains of staphylococci of intestinal origin which were tested, 15 were capable of producing enterotoxin. Consequently, the enterotoxic strains are encountered rather frequently in the intestine of healthy individuals. It is evident that all of the strains, regardless of chromogenesis, have the capacity to produce entertoxin. Of the 15 enterotoxic strains of staphylococci that were isolated, 6 coagulated plasma, and 13 gave a zone of hemolysis in a blood agar. The biochemical tests - the reaction of the dish hemolysis and the plasma coagulation - cannot be adequate criteria for differentiating the enterotoxic strains of the staphylococcus, and cannot supersede the biological test on kittens and cats, which are sensitive to the staphylococcal enterotoxin. In connection with the discovery of the enterotoxic strains among the staphylococci, isolated from the fecal pellets of healthy humans, there arises a question as to the possibility of an infection of products and food by the staphylococci of intestinal origin, and subsequently, about their role in outbreaks of food intoxication of a staphylococcal etiology.
