PNB Sensitivity Test is a ready to use Lowenstein Jensen solid media with para-nitrobenzoic (PNB) acid for differentiating primary isolates into Mycobacterium tuberculosis complex and Non-Tuberculous Mycobacteria.
Identification of the primary isolate as belonging to Mycobacterium tuberculosis complex or Non-Tuberculous Mycobacteria (NTM) can be ascertained by performing a few simple tests i.e. tolerance to para-nitrobenzoic acid (PNB), niacin production test, nitrate reduction test, catalase activity at 68°C / pH 7.0, besides observing their growth rate at 25°C and 37°C, photochromogenecity, colony characteristics and morphological appearance and pigment production.
Reagent:
PNB Sensitivity Test is provided as ready to use solid L.J. slants incorporated with para-nitrobenzoic (PNB) acid 500 mg/L.
