Abstract
The aim of this study was to evaluate real-time PCR (LightCycler) kits for the detection of methicillin-resistant Staphylococcus aureus in enrichment broth using 200 sets of patient screening swab samples. One hundred sets were processed using a lysostaphin/lysozyme extraction method and a further 100 were tested using a column extraction kit. The PCR kits with lysostaphin/lysozyme lysis showed 95.7% sensitivity, 90.8% specificity, and negative and positive predictive values of 98.6% and 75.9%, respectively, compared with 88%, 95.9%, 84.6% and 95.9%, respectively, with the column extraction kit.
