antimicrobial susceptibilities and distribution of resistance genes for β-lactams in streptococcus pneumoniae isolated in hamadan
results the number of s. pneumoniae isolates resistant to benzylpenicillin, imipenem, oxacillin and ceftazidime were 94.5%, 100%, 100%, and 21.8%, respectively. analysis of mutation in the genes for pbp showed that 85% of isolates had mutations in pbp2x, pbp2b and pbp1a. susceptibility to benzylpenicillin was decreased once the number of mutated pbp genes in s. pneumonia increased. according to...
متن کاملAntimicrobial Susceptibilities and Distribution of Resistance Genes for β-Lactams in Streptococcus pneumoniae Isolated in Hamadan
BACKGROUND β-lactams resistant Streptococcus pneumoniae are an emerging problem throughout the world. Several resistance mechanisms have been reported, including expression of drug-destroying enzymes such as β-lactamases, altered drug targets such as conformational changes in PBPs, decreased bacterial permeability, and increased drug efflux. OBJECTIVES The present study aimed to determine the...
متن کاملMacrolide Resistance in Streptococcus pneumoniae
Streptococcus pneumoniae is a common commensal and an opportunistic pathogen. Suspected pneumococcal upper respiratory infections and pneumonia are often treated with macrolide antibiotics. Macrolides are bacteriostatic antibiotics and inhibit protein synthesis by binding to the 50S ribosomal subunit. The widespread use of macrolides is associated with increased macrolide resistance in S. pneum...
متن کاملRelation 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...
