WebMar 30, 2024 · MRSA is defined as a strain of S. aureus with a minimum inhibitory concentration (MIC) of oxacillin ≥ 4 mcg/mL [].MRSA is primarily mediated by the mecA gene encoding the penicillin-binding protein 2a. Today, because cefoxitin is a strong inducer of mecA, it is widely used to replace the antibiotic oxacillin in the detection of MRSA … Web14 hours ago · The MIC testing results confirmed that all 7 isolates were MDR strains and all were resistant to ampicillin and ceftriaxone (Table 4). Then, the resistance index (MARI) against 14 antibiotics were calculated for the high and low proteolytic activity groups and the average MARI scores were 0.41 and 0.31, respectively.

In microbiology, the minimum inhibitory concentration (MIC) is the lowest concentration of a chemical, usually a drug, which prevents visible growth of a bacterium or bacteria. MIC depends on the microorganism, the affected human being (in vivo only), and the antibiotic itself. It is often expressed in micrograms per milliliter (μg/mL) or milligrams per liter (mg/L).
