Molecular genetic basis of antimicrobial agent resistance in Mycobacterium tuberculosis: 1998 update.
Knowledge of the molecular genetic basis of resistance to antituberculous agents has advanced rapidly since we reviewed this topic 3 years ago. Virtually all isolates resistant to rifampin and related rifamycins have a mutation that alters the sequence of a 27-amino-acid region of the beta subunit of ribonucleic acid (RNA) polymerase. Resistance to isoniazid (INH) is more complex. Many resistan...
متن کاملMolecular Characterization and Antimicrobial Resistance of Uropathogenic Escherichia coli
Background:Urinary Tract Infections (UTIs) are the most common infectious diseases in childhood. The Uropathogenic Escherichia coli (UPEC) strains account for as much as 80% of UTIs. Objective:From a clinical perspective, it is important to know which virulence factors and antibiotic resistance properties are present in UPEC strains in pediatrics. Therefore, this study was carried out...
متن کاملMolecular detection of antimicrobial resistance.
The determination of antimicrobial susceptibility of a clinical isolate, especially with increasing resistance, is often crucial for the optimal antimicrobial therapy of infected patients. Nucleic acid-based assays for the detection of resistance may offer advantages over phenotypic assays. Examples are the detection of the methicillin resistance-encoding mecA gene in staphylococci, rifampin re...
متن کاملMolecular Mechanisms of Antimicrobial Resistance
In the last 50 years bacteria have demonstrated a remarkable ability to develop and share resistance to every antibiotic that has been developed, often by quite unexpected mechanisms and much more readily than was originally predicted (Spratt, 1994). Antibiotic resistant bacteria can live and multiply in the presence of therapeutic levels of antibiotics. They can be resistant in their natural s...
متن کاملGenetic recombination in mycobacteria.
Evidence for genetic recombination between Mycobacterium smegmatis strain Rabinowitchi (Rab) and strain Jucho or PM5 is presented. Backcrosses of recombinants by either parental strain indicated four different types of mating behavior, suggesting that the mycobacterial compatibilities are controlled by at least two different factors. No sex factor that transfers at a high frequency or that is s...
