BACKGROUND Treatment of chronic sinusitis is complicated due to increase of antibiotic-resistant bacteria. The aim of this study was to determine the multidrug resistance (MDR) pattern of the bacteria causing chronic sinusitis in north of Iran. METHODS This cross-sectional study was carried out on patients with chronic sinusitis. Bacterial susceptibility to antimicrobial agents was determined...

ceftazidime, and imipenem (MIC, 132 mg/L); intermediate susceptibility to aztreonam; and susceptibility to piperacillin. Such a phenotype suggested MBL production, which was confirmed by the imipenem-EDTA double-disk synergy test [6]. The MBL determinant was subsequently identified as blaIMP-4 by molecular techniques [7]. The patient, who had just been transferred to the neurosurgery department...

AIM During 2010-2011, six Providencia spp. (five Providencia stuartii and one Providencia rettgeri) urine isolates with unusual resistance phenotype were collected from various hospital units at the University Hospital Split in Croatia. The aim of the study was to analyze the mechanisms of resistance to expanded-spectrum cephalosporins. METHODS The antimicrobial susceptibility to a wide range...

OBJECTIVE Pseudomonas aeruginosa is one of the most important causes of nosocomial infections and can acquire resistant to many antimicrobials, including β-lactams. The aim of this study was to detect the prevalence of SHV type extended-spectrum beta-lactamase (ESBL), antimicrobial resistance patterns of the P. aeroginusa and risk factors in hospitalized patients in two teaching hospitals in Sa...

The purpose of this study was to determine the microbiological profile of diabetic foot infections (DFIs) and assess the antibiotic susceptibility of the causative agents. Data were obtained from a retrospective analysis of DFI samples collected from June 2007 to July 2008. Specimens were cultured using optimal aerobic and anaerobic microbiological techniques, and antibiotic susceptibility test...

introduction: antibiotic resistance among bacteria in particular those producing extended spectrum beta lactamases (es- bls) has a very significant role in hospital acquired infections. some of the gram negative bacilli including klebsiella pneu- monia and escherichia coli are known to be esbl producers which cause uncontrollable infections because they are also often resistant to other antimic...

BACKGROUND/AIMS We examined the prevalence of extended-spectrum β-lactamase (ESBL) production and the impact of ESBL on clinical outcomes in cancer patients with Enterobacter spp. bacteremia. METHODS Using prospective cohort data on Enterobacter bacteremia obtained between January 2005 and November 2008 from a tertiary care center, the prevalence and clinical impact of ESBL production were ev...

AIM To investigate the characteristics of meticillin-resistant S. aureus (MRSA), extended-spectrum (ESBL), and plasmid-mediated AmpC beta-lactamase producing Gram-negative bacteria causing skin and soft tissue infections (SSTIs) in hospital and outpatient settings of Zenica-Doboj Canton, Bosnia and Herzegovina. METHODS Antibiotic susceptibility was determined by disc-diffusion and broth micro...
