title: Circulation of enterotoxigenic strains of Staphylococcus aureus in humans and their environment.
abstract: In the study of eight groups of staphylococci covering 870 strains of Staphylococcus aureus, isolated from humans and ten kinds of animals, it was found that a total of 271 strains [31.4%] produced some of the types of staphylococcal enterotoxin [SE]. With the exception of 34 strains isolated from staphylococcal enterotoxicosis the other strains were unrelated to this disease. While among healthy persons 14% [students]---57% [employees of food industry undertakings] enterotoxigenic strains were detected, in persons under medical care SE positivity was within the range of 30---40%. Cases with staphylococcal enterotoxicosis included 68% of enterotoxigenic strains. In animals the incidence of SE-producing strains amounted to some 2 per cent. The most frequent SE type was type A [50%], the most rare type was type E [about 2%]; strains producing more than one SE type were represented in 10% of cases. There is discussed the importance of the obtained findings for man from the aspect of enterotoxigenity.
