Rapid Detection of ß-lactamase Enzymes

MASTDISCS® ID Nitrocefin discs enables rapid detection of ß-lactamase enzymes. The presence of ß lactamase confers resistance to penicillin and cephalosporin’s, resulting in inactivation of these antibiotics.

Nitrocefin is a chromogenic cephalosporin that has been found to be effective in the detection of all known β-lactamase enzymes. It can be used in the rapid testing of isolated colonies of Neisseria gonorrhoeae, Moraxella catarrhalis, Staphylococcus spp., Haemophilus influenzae and anaerobic bacteria.

MASTDISCS® ID Nitrocefin discs are easy to use. Simply smear a colony onto a moistened disc, and observe for a colour change. A change to red indicates a positive result. The test takes only 5 minutes for the colour reaction to develop for the majority of bacterial strains. A positive result should be interpreted as resistance to penicillin or cephalosporin activity.

Available from our stock range, with 50 tests per vial.
