OBJECTIVES To compare the in vitro activity of moxifloxacin and ciprofloxacin against 226 nosocomial isolates of Acinetobacter baumannii from 44 hospitals in the UK. METHODS MICs of ciprofloxacin and moxifloxacin were determined by Etest. PCR analysis was used to detect chromosomal mutations in the gyrA and parC genes. Isolates resistant to ciprofloxacin and susceptible to moxifloxacin were e...
Background and purpose: Pseudomonas aeruginosa is an opportunistic pathogen in patients with chronic respiratory disease or in immunocompromised hosts. This bacterium shows intrinsic and acquired resistance to diverse antimicrobial agents. An important mechanism of resistance to fluoroquinolones in P. aeruginosa is the mutation in gyrA, a subunit of topoisomerases II. The aim of this study was ...
Background and Aim: The emergence of nonfermenter bacteria that are resistant to multidrug resistant ESBL are nowadays a principal problem for hospitalized patients. The present study aimed at surveying the emergence of nonfermenter bacteria resistant to multi-drug ESBL producing isolated from patients blood samples using BACTEC 9240 automatic system in Shiraz. Materials and Methods: In ...
Introduction: Stenotrophomonas maltophilia is intrinsically resistant to many antimicrobials. Like Pseudomonas spp., this bacterium has a remarkable ability to cause infections, particularly in the respiratory and urinary tracts. This study aims to determine the antimicrobial resistance pattern of S. maltophilia isolates collected from a tertiary care setting and frequency of multi, extensively...
Received: 6 Jul, 2015 Accepted: 16 Sep, 2015 Abstract Background & Aims: In recent years, the emergence of multi drug resistant Klebsiella pneumonia is responsible for many therapeutic problems all over the world. Nowadays carbapenems are often considered as the final options for antibiotic treatment of infections caused by most Gram-negative bacilli. The aim of this study was to dete...
background: multidrug resistant enterobacteriaceae which was confined to the hospital environments is now emerging in the domestic food related environments as well. the main objective of the present study was to investigate the prevalence of antibiotic resistant enterobacteriaceae in the domestic food related environments. methods: resistance to ampicillin, chloramphenicol, ciprofloxacin, gen...
INTRODUCTION The goal of this study was to assess how resistance to quinolones, fluoroquinolones and trimethoprim/sulfamethoxazole relates to the virulence potential and phylogenetic background of clinical Escherichia coli isolates. METHODS Among 150 uropathogens (21% resistant to quinolones, 12% resistant to fluoroquinolones and 29.3% resistant to trimethoprim/sulfamethoxazole), E. coli phyl...
The activity of nitrofurantoin was tested against 300 isolates of Enterococcus faecium, Enterococcus faecalis, and Enterococcus gallinarum. No isolates tested were resistant to nitrofurantoin (MIC, >/=128 microg/ml), including vancomycin-resistant E. faecium isolates with vanA- and vanB-positive genotypes and vancomycin-resistant E. gallinarum isolates. We conclude that nitrofurantoin may provi...
objective: aminoglycosides are highly potent, broad-spectrum antibiotics with many desirable properties for the treatment of life-threatening infections. escherichia coli (e. coli) is the most common cause of urinary tract infection (uti). antibiotic resistance has recently become prevalent. enzymatic inactivation of aminoglycosides by aminoglycoside-modifying enzymes is the main mechanism of r...
Background and objectives: Carbapenem-resistant and biofilm producing Enterobacteriaceaeare a major health problem. This study was carried to determine the antibacterial and antibiofilm activity of grape seed extract (GSE) against carbapenem-resistant and biofilm producing Enterobacteriaceae isolates. Methods: Antibiotics susceptibility pattern...
