Ancestral antibiotic resistance in Mycobacterium tuberculosis.
Chemotherapeutic options to treat tuberculosis are severely restricted by the intrinsic resistance of Mycobacterium tuberculosis to the majority of clinically applied antibiotics. Such resistance is partially provided by the low permeability of their unique cell envelope. Here we describe a complementary system that coordinates resistance to drugs that have penetrated the envelope, allowing myc...
متن کاملEvaluation of Gene Mutations Involved in Drug Resistance in Mycobacterium Tuberculosis Strains Derived from Tuberculosis Patients in Mazandaran, Iran, 2013
Drug resistance (especially multiple drug resistance) in Mycobacterium tuberculosis makes global concerns in treatment and control of tuberculosis. Rapid diagnosis of drug resistant strains of the bacteria has vital importance in the prognosis of the disease. The aim of this study was to identify the mutations responsible for drug resistance in Mycobacterium tuberculosis strains derived from pa...
متن کاملPoint-Mutations in embB306 Gene and Their Association with Resistance to Ethambutol in Mycobacterium tuberculosis in Clinical Isolates
Background & Objective: Mutations in embB306 gene and their association with resistance to ethambutol (EMB) in Mycobacterium tuberculosis (M. tuberculosis) have not been fully investigated. The aim of this study was to investigate the point-mutations in emb306B gene and their association with resistance to EMB in M. tuberculosis. Materials & Methods: This case (M. tuberculosis resistant to EMB...
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 کاملThe competitive cost of antibiotic resistance in Mycobacterium tuberculosis.
Mathematical models predict that the future of the multidrug-resistant tuberculosis epidemic will depend on the fitness cost of drug resistance. We show that in laboratory-derived mutants of Mycobacterium tuberculosis, rifampin resistance is universally associated with a competitive fitness cost and that this cost is determined by the specific resistance mutation and strain genetic background. ...
