title: Use of multiplex PCR to detect classical and newly described pyrogenic toxin genes in staphylococcal isolates.
abstract: Staphylococcus aureus may contain one or more genes that encode a variety of immunomodulatory pyrogenic toxins (PTs), including the staphylococcal enterotoxins and toxic shock syndrome toxin (TSST). The PTs interact with several cellular targets to produce disease, such as food poisoning and toxic shock syndrome. At present, nine serologically distinct enterotoxins and one immunoreactive form of TSST have been identified and characterized. As isolates of S. aureus are further assessed, it is anticipated that this number will increase. To facilitate screening, a multiplex PCR was designed to simultaneously determine which of these 10 currently known PT genes an individual S. aureus isolate possesses. We show here, using S. aureus isolates with characterized PT phenotypes, that this novel PCR technique reliably detects each of the known PTs in a single reaction.
