Isoniazid (INH) and Rifampicin (RIF), the two most potent antituberculous drugs, kill more than 99% of tubercule bacilli within 2 months of initiation of therapy . Therefore, the emergence of strains resistant to either of these drugs causes major concern, as it leaves only drugs that are far less effective, have more toxic side effects, and result in higher death rates, especially among HIV-infected persons. Drug resistance surveillance was restored in the late 90s, with reports showing also multidrug resistance (MDR) to both RIF and INH. A WHO study showed that in the period 2000-2004 about 20% of clinical samples tested showed MDR. Up to date it is well known that 95% rifampin (RMP) resistance is associated with rpoB gene mutations and most of mutations frequency, associated with isoniazid (INH) resistance, are discovered in 315 codon of katG gene and in the regulatory region of inhA gene.
MTB Real-TM Resistance is an in vitro allele-specific Real Time PCR test for detection in cultures, sputum and other biological materials of specific Mycobacterium tuberculosis mutations in rpoB, katG and inhA genes associated with INH or RIF resistance: rpoB codon 531 (2 mutations: Ser-Leu and Ser-Trp), rpoB codon 526-1 (3 mutations: His-Tyr, His-Asp, His-Arg), rpoB codon 526-2 (3 mutations: His-Leu, His-Asn, His-Pro), rpoB codon 516 (1 mutation: Asp-Val), rpoB codon 533 (1 mutation: Leu-Pro), katG codon 315 (3 mutations: Ser-Thr, Ser-Asn, Ser-Thr*), inhA codon 209 (1 mutation C209T). Each mutation is detected on a single specifi c channel using a single tube; wild-type gene is detected as control on a different channel.
