An rapid acidometric method for performing a beta-lactamase test on Haemophilus spp., S. aureus, and N. gonorrhoeae
Hardy Diagnostics Beta-Lactamase Test is a means of detecting the enzyme beta-lactamase, which confers penicillin resistance to various bacterial organisms by cleaving the beta-lactam ring of penicillins and cephalosporin antibiotics
This acidometric method is recommended for use in testing beta-lactamase production by Neisseria gonorrhoeae, Haemophilus species and Staphylococcus species
Each tube included in the kit contains the following in the reconstituted mixture, per liter of solvent: Penicillin 15.0 gm, Sodium Chloride 5.0 gm, Trisodium Citric Acid 1.5 gm, Trisodium Phosphate 0.3 gm, Phenol Red 18.0 mg
Beta-Lactamase Test powder should appear white in color
The reconstituted reagent should appear pink in color
