[Occurrence of Staphylococcus aureus enterotoxigenic strains isolated from pregnant women with pathology]

137 S. aureus strains, isolated from the larynx of pregnant women in cases of pathology, were studied for the formation of staphylococcal enterotoxins of types A and B (SEA and SEB) by the indirect hemagglutination test. The study revealed that SEA was produced by 35.0% and SEB, by 56.6% of the strains under study. The proportion of SEA and SEB producers among staphylococci isolated from mothers and children was, respectively, 18.4% and 20.0%, 89.41% and 67.5%. The number of enterotoxigenic staphylococci in the upper respiratory tract of newborn infants and mothers practically coincided with that in mothers. The occurrence of SEA- and SEB-producing enterotoxigenic strains in the medical personnel was 25.5% and 62.7% respectively.
