Nitrocef Matchbook™, chromogenic nitrocefin test for beta lactamase, on paper strip, 10 tests per packageNew Easy-to-Use MatchBook Format. Hardy Diagnostics now offers a more convenient way of testing ß-lactamase activity in bacteria. The new Nitrocef MatchBook™ is a rapid test that allows you to quickly pick your colonies and perform the test at the same time! Easier and faster than a disk!The rapid Nitrocef test consists of a paper match-stick that is impregnated with the Nitrocefin reagent, which is a chromogenic cephalosporin. This rapid test can yield clinically relevant information earlier than an MIC test. A positive ß-lactamase test can predict resistance to such antibiotics as penicillin, ampicillin, amoxicillin, and other ß-lactamase containing drugs for the following organisms:• Neisseria gonorrhoeae• Haemophilus spp.• Moraxella (Branhamella) catarrhalis• Staphylococcus spp.• Enterococcus spp.• Anaerobes (such as some species of Bacteroides, Porphyromonas, Clostridium, Fusobacterium, Prevotella)The rapid Nitrocef MatchBookTM can be used for all of the above organisms with results in 5 minutes or less, with the exception of some Staphylococcus spp. that may take up to one hour. The ß-lactamase test is preferred to disk diffusion and agar dilution for the detection of plasmid-mediated beta-lactamase resistance in gonococci. Now contains a larger reaction pad.
One or multiple beta-lactam test reagent(s) [e.g., a cephalosporin (nitrocefin, cefpodoxime) or beta-lactamase inhibitor (clavulanic acid)] in an impregnated disc, strip, or dehydrated in a microplate, intended to be used in microbial testing to detect beta-lactamase enzyme [e.g., extended-spectrum beta-lactamase (ESBL)] production by a microorganism isolated from a clinical specimen by culture.
