| 摘要 |
The present invention provides methods, compositions and diagnostic kits for the detection of Staphylococcus Aureus (SA) and antibiotic resistant forms and variants thereof, such as methicillin-resistant Staphylococcus aureus (MRSA), vancomycin- resistant Staphylococcus aureus (VRSA), mupirocin- resistant Staphylococcus aureus (mupSA), and the like, in a sample population. The invention preferably involves the improvements of bacterial sampling by means of SA enrichment, followed by SA cell disruption and amplification procedures incorporating the use of multiplex assays for SA specific genes, such as mecA and coagulase negative Staphylococci (CONS) specific genes such as tufA, for SA identification and identification of its known species. This provides means for controlling for the thirty or more known CONS species in assessing SA samples, especially those CONS species that may carry antibiotic resistance genes, such as SCCmec. |
