Table 5. Comparison of direct inoculation of MRSA-ID, ORSA, oxacillin-MSA and broth enrichment (BE) prior to inoculation on oxacillin-MSA in detection of methicillin-resistant Staphylococcus sciuri (MRSS) verified by identification by automated Vitek2 System and mecA PCR.
| Medium | Number of MRSS strains detected (number after 48 h) | Sensitivity (%) | Specificity (%) | ||
