This rapid test can yield clinically relevant information earlier than an MIC test.

• Easy-to-use disk format
• Conveniently test ß-lactamase activity in bacteria
• Most organisms yield results in five minutes or less

New Easy-to-Use Disk Format

The rapid Nitrocef Disk test can be used for all of the above organisms with results in five 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. These HardyDisks™ are packaged loose in a glass vial. For a cartridge (tube) configuration.

Hardy Diagnostics now offers a convenient way of testing ß-lactamase activity in bacteria. The rapid Nitrocef test consists of a disk 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)
