Mechanisms of zidovudine resistance in bacteria.
Unlike their parent strains, zidovudine-resistant derivatives of Escherichia coli KL16 and Salmonella typhimurium NCTC 5710 were found to be incapable of incorporating radiolabelled thymidine into their chromosomal DNA. Since incorporation was still prevented in the presence of EDTA, resistance to zidovudine was not associated with a permeability barrier, but appeared to result from the loss of...
متن کاملMechanisms of polymyxin resistance: acquired and intrinsic resistance in bacteria
Polymyxins are polycationic antimicrobial peptides that are currently the last-resort antibiotics for the treatment of multidrug-resistant, Gram-negative bacterial infections. The reintroduction of polymyxins for antimicrobial therapy has been followed by an increase in reports of resistance among Gram-negative bacteria. Some bacteria, such as Klebsiella pneumoniae, Pseudomonas aeruginosa, and ...
متن کاملCopper resistance mechanisms in bacteria and fungi.
Copper is both an essential micronutrient and a toxic heavy metal for most living cells. The presence of high concentrations of cupric ions in the environment promotes the selection of microorganisms possessing genetic determinants for copper resistance. Several examples of chromosomal and plasmid copper-resistance systems in bacteria have been reported, and the mechanisms of resistance have st...
متن کاملResistance mechanisms of bacteria to antimicrobial compounds
Resistance has been defined as the temporary or permanent ability of an organism and its progeny to remain viable and/or multiply under conditions that would destroy or inhibit other members of the strain. Bacteria may be defined as resistant when they are not susceptible to a concentration of antibacterial agent used in practice. Traditionally, resistance refers to instances where the basis of...
متن کاملMechanisms of antibiotic resistance determined by resistance-transfer factors.
Unowsky, Joel (Northwestern University Medical School, Chicago, Ill.), and Martin Rachmeler. Mechanisms of antibiotic resistance determined by resistance-transfer factors. J. Bacteriol. 92:358-365. 1966.-This study was concerned with the mechanism of expression of drug resistance carried by resistance-transfer (R) factors of two types: fi(-) (negative fertility inhibition) and fi(+) (positive f...
