Relation between Resistance to Antipseudomonal β-Lactams and ampC and mexC Genes of Pseudomonas aeruginosa
Background: In order to select a better antibiotic choice for treatment of Pseudomonas aeruginosa infections, this study was conducted to determine the frequency of resistance to some antipseudomonal β-lactams in P. aeruginosa isolates from patients in Tehran, Iran. In addition, the relation between presence of genes known to be responsible for resist...
متن کاملReplicon Typing of Plasmids Encoding Resistance to Newer β-Lactams
Polymerase chain reaction-based replicon typing represents a novel method to describe the dissemination and follow the evolution of resistance plasmids. We used this approach to study 26 epidemiologically unrelated Enterobacteriaceae and demonstrate the dominance of incompatibility (Inc) A/C or Inc N-related plasmids carrying some emerging resistance determinants to extended-spectrum cephalospo...
متن کاملMechanisms of resistance and clinical relevance of resistance to β-lactams, glycopeptides, and fluoroquinolones.
The widespread use of antibiotics has resulted in a growing problem of antimicrobial resistance in the community and hospital settings. Antimicrobial classes for which resistance has become a major problem include the β-lactams, the glycopeptides, and the fluoroquinolones. In gram-positive bacteria, β-lactam resistance most commonly results from expression of intrinsic low-affinity penicillin-b...
متن کاملOritavancin Combinations with β-Lactams against Multidrug-Resistant Staphylococcus aureus and Vancomycin-Resistant Enterococci.
Oritavancin possesses activity against vancomycin-resistant enterococci (VRE) and methicillin-resistantStaphylococcus aureus(MRSA).In vitrodata suggest synergy between beta-lactams (BLs) and vancomycin or daptomycin, agents similar to oritavancin. We evaluated the activities of BLs combined with oritavancin against MRSA and VRE. Oritavancin MICs were determined for 30 strains, 5 each of MRSA, d...
متن کاملResistance to β-Lactams in Neisseria ssp Due to Chromosomally Encoded Penicillin-Binding Proteins
Neisseria meningitidis and Neisseria gonorrhoeae are human pathogens that cause a variety of life-threatening systemic and local infections, such as meningitis or gonorrhoea. The treatment of such infection is becoming more difficult due to antibiotic resistance. The focus of this review is on the mechanism of reduced susceptibility to penicillin and other β-lactams due to the modification of c...
