Comparison of Two Commercial PCR Methods for Methicillin-Resistant Staphylococcus aureus (MRSA) Screening in a Tertiary Care Hospital
Nose/throat-swabs from 1049 patients were screened for MRSA using CHROMagar MRSA, LightCycler Advanced MRSA, and Detect-Ready MRSA. Results were compared to the CHROMagar MRSA results, which was set as reference system. MRSA was detected in 3.05% of the patients with CHROMagar MRSA. LightCycler MRSA Advanced showed a higher clinical sensitivity (84.38%) than Detect-Ready MRSA (57.69%).The negat...
متن کاملAssessment of three rapid methods for the detection of methicillin-resistant Staphylococcus aureus.
We evaluated three rapid methods to detect methicillin-resistant Staphylococcus aureus (MRSA) and compared them with PCR amplification of mecA. A total of 103 S. aureus strains were studied by MRSA-Screen, BBL Crystal, Velogene Genomic and mecA PCR. All the methods detected the 61 MRSA strains having the mecA gene, showing 100% sensitivity and specificity. Despite the correlation between all th...
متن کاملMolecular Characterization and SCCmec in Methicillin Resistant Staphylococcus aureus from Healthy Worker Nasal Swab in Larestan Hospital
Background and Aims: The aim of present study was to investigate the molecular characteristic of Staphylococcus aureus to detect mec A gene and to type SCCmec in strain isolated from healthy worker at Larestan Hospital. Material and Methods: This study was carried out from the 250 nasal swab healthy worker at Larestan hospital. Multiplex polymerase chain reaction for mecA gene was perf...
متن کاملDetermination of PCR-ELISA Diagnostic Value in Comparison With Classical Methods and PCR to Detect Resistance to Methacillin
Background and Aims: High prevalence of Methicillin Resistant Staphylococcus Aureus isolates (MRSA) as well as the multi-drug resistance in this bacterium causes difficulties in the treatment of infections due to these bacteria. Hence, detection of MRSA isolates by rapid and accurate methods is necessary. PCR-ELISA is an accurate and molecular technique that is used for the detection of several...
متن کاملRapid screening for carriage of methicillin-resistant Staphylococcus aureus by PCR and associated costs.
PCR tests for the rapid and valid detection of methicillin-resistant Staphylococcus aureus (MRSA) are now available. We evaluated the costs associated with contact screening for MRSA carriage in a tertiary-care hospital with low MRSA endemicity. Between 1 October 2005 and 28 February 2006, 232 patients were screened during 258 screening episodes (644 samples) for MRSA carriage by GenoType MRSA ...
