Features

• Hardy Diagnostics Nitrocef Disks™ are intended for use in the rapid testing of isolated colonies of Neisseria gonorrhoeae, Moraxella (Branhamella) catarrhalis, Staphylococcus spp., Haemophilus influenzae, Enterococcus spp., and some anaerobic bacteria for the production of beta-lactamase
• Nitrocef Disks™ should appear as 0.25 inch (in diameter) filter paper disks imprinted with ß, and white to yellow in color
• A positive beta-lactamase result is recorded when the Nitrocef Disk™ changes in color from its original yellow to orange or red
• Most positive bacterial strains will produce a color change within 5 minutes
• Some staphylococci, however, may take up to 60 minutes for a positive result
