Mycobacterium tuberculosis Pyrazinamide Resistance Determinants: a Multicenter Study
Pyrazinamide (PZA) is a prodrug that is converted to pyrazinoic acid by the enzyme pyrazinamidase, encoded by the pncA gene in Mycobacterium tuberculosis. Molecular identification of mutations in pncA offers the potential for rapid detection of pyrazinamide resistance (PZA(r)). However, the genetic variants are highly variable and scattered over the full length of pncA, complicating the develop...
متن کاملA STUDY OF MYCOBACTERIUM TUBERCULOSIS DRUG RESISTANCE IN PULMONARY TUBERCULOSIS
Tuberculosis remains a major public health problem in both developing and developed countries. Drug-resistant tuberculosis is an increasing health problem and serious challenge to tuberculosis (TB) control programs. Information about the susceptibility pattern of Mycobacterium tuberculosis isolates against anti-tuberculosis drugs is an important aspect to TB control. The objectives of the s...
متن کاملPyrazinamide Drug Resistance in Mycobacterium Tuberculosis: A Minireview
Pyrazinamide (PZA) is a nicotinamide analog that is used as a frontline drug to treat tuberculosis (TB). It has special place in modern TB therapy, as it appears to kill a population of semi dormant tubercle bacilli persisting in the body. It is important drug because of its sterilizing activity against semi dormant tubercle bacilli. Although PZA has a very high in vivo activity, it’s in vitro ...
متن کاملPyrazinamide resistance among South African multidrug-resistant Mycobacterium tuberculosis isolates.
Pyrazinamide is important in tuberculosis treatment, as it is bactericidal to semidormant mycobacteria not killed by other antituberculosis drugs. Pyrazinamide is also one of the cornerstone drugs retained in the treatment of multidrug-resistant tuberculosis (MDR-TB). However, due to technical difficulties, routine drug susceptibility testing of Mycobacterium tuberculosis for pyrazinamide is, i...
متن کاملElucidating Pyrazinamide Resistance in Mycobacterium Tuberculosis by Molecular Docking
Pyrazinamide (PZA) an important drug in the anti-tuberculosis therapy, activated by an enzyme Pyrazinamidase (PZase). The basis of PZA resistance in Mycobacterium tuberculosis (Mtb) is owing to mutation in pncA gene coding for PZase. The identification of the structural or functional defects in the mutant enzymes leading to resistance still remains an area to be explored. The Wild-type (WT) and...
