Abstract
A highly sensitive test system, based on the method of immuno-PCR, was developed for the detection of two staphylococcal toxins: enterotoxin A (SEA) and toxic shock syndrome toxin (TSST). A key element of the developed systems was obtaining supramolecular complexes of bisbiotinylated oligodeoxynucleotides and streptavidin, which were used as DNA tags. Specificity studies showed no cross-reactivity when determining SEA and TSST. The sensitivity of detection of these toxins in the culture supernatants S. aureus was not less than 10 pg/mL.
