Mycobacterium Tuberculosis INH Resistance

Short Description:

This kit is used to qualitatively detect the gene mutation of the 315th amino acid of the katG gene (K315G>C) and the gene mutation of the promoter region of the InhA gene (- 15 C>T).

HWTS-RT002A-Mycobacterium Tuberculosis INH Detection Kit (Fluorescence PCR)


Myanmar FDA


Isoniazid, a key anti-tuberculosis drug introduced in 1952, is one of the most effective drugs for combined treatment of active tuberculosis and a single drug for latent tuberculosis.

KatG is the main gene encoding catalase-peroxidase and katG gene mutation can promote the synthesis of mycolic acid cell wall, making the bacteria resistant to isoniazid. KatG expression is negatively correlated with changes in INH-MIC, and a 2-fold decrease in katG expression results in a slightly larger 2-fold increase in MIC. Another cause of isoniazid resistance in mycobacterium tuberculosis occurs when base insertion, deletion or mutation occurs in the InhA gene locus of mycobacterium tuberculosis.
