WebAll gonococcal isolates were tested for production of ß-lactamase by the chromogenic cephalosporin method (Nitrocefin disc). The minimum inhibitory concentration (MIC) of ceftriaxone for N. gonorrhoeae isolates was determined by the E test method using Ceftriaxone Ezy MIC™ Strip (CTR) (0.016–256 µg/ml) (HIMEDIA Catalogue Number: … WebJul 13, 2013 · C. nitrocefin - the chromogenic cephalosporin test using nitrocefin is the most sensitive and specific test for detection of beta lactamase. Acidimetric tests employing penicillin are less expensive, but not as sensitive, as the nitrocefin assay. A Staph aureus isolate has an MIC of 4 ug/mL to Oxacillin.
