WebOct 18, 2006 · We compared MRSA Select to mannitol-salt agar with 8 μg/ml cefoxitin for the detection of methicillin-resistant Staphylococcus aureus (MRSA) from 6,199 clinical samples submitted for MRSA screening. The sensitivities and specificities of MRSA Select and mannitol-salt agar with cefoxitin were 98% and 92% versus 90% and 78%, … WebDec 26, 2024 · The cefoxitin disk diffusion and oxacillin broth microdilution assays categorized 100% and 61.3% of isolates to be MRSA, respectively. The chromogenic media tested confirmed their suitability to reliably screen for mecC -harboring MRSA.

Cefoxitin disc diffusion test for detection of meticillin …
WebTwo oxacillin disk methods were compared with a cefoxitin disk diffusion test for detection of methicillin-resistant Staphylococcus aureus (MRSA), with PCR for mecA as the reference method. When tested with 115 MRSA and 350 methicillin-susceptible S. aureus isolates, the cefoxitin disk test (specificity 100%, sensitivity 96.5%) was superior to the … WebMaterials and Methods: A total of 150 S. aureus isolates were tested using cefoxitin disk diffusion, oxacillin salt agar (OSA), latex agglutination test for penicillin binding protein 2a antigen, chromogenic MRSA ID agar, and mecA PCR. Results: Using PCR as the gold standard, 91 (60.66%) of 150 clinical S. aureus strains WebJul 18, 2024 · Introduction. Based on the antibiotic susceptibilities, Methicillin resistance in S. aureus is defined as an oxacillin minimum inhibitory concentration (MIC) of greater than or equal to 4 micrograms/mL.
