摘要
The ability of five enterotoxigenic Staphylococcus aureus strains, isolated from mastitic milk, to produce enterotoxins in homemade cheese kept at room temperature for 20-25 d or at +15 degrees C 24 h was examined. The inoculum concentration was 1,5 - 8,5 x 10(2) S. aureus cells/ml milk. Enterotoxin D was produced within 4-6 h in cheeses kept at room temperature and during 8 days in cheeses kept at + 15 degrees C while enterotoxin C was not produced at either temperature during the course of the experiment and enterotoxin B only at +15 degrees C by one of the strains. The SET-EIA was more sensitive compared with Ridascreen.
