BACKGROUND The empirical therapy of urinary tract infections (UTI) relies on the predictability of the agents causing UTI and knowledge of their antimicrobial susceptibility patterns. METHODS In a prospective study undertaken over a 14-month period, 5136 samples from patients suspected of having a UTI were analyzed, of which 676 were culture-positive.(More)
PURPOSE Urinary tract infection (UTI) is the most common nosocomial infection among hospitalized patients. Meanwhile, most frequent infections involving enterococci affect the urinary tract. The aims of this study were to investigate the susceptibility pattern of isolated enterococci from UTI and the prevalence of virulence genes. METHODS The study used(More)
Helicobacter pylori-associated infection is extremely common in Iran, as in other developing countries, but few data exist on the susceptibility of H. pylori to antimicrobials commonly used in the eradication schedules in this country. This study was performed to determine the resistance rate to six antimicrobial agents used in the treatment of H. pylori(More)
The prevalence of metallo-β-lactamase (MBL) production among 104 clinical isolates of Pseudomonas aeruginosa from northwest of Iran was investigated by phenotypic and polymerase chain reaction (PCR) methods. Thirty-nine (37.50%) of isolates were MBL positive by double-disk synergy test. Results of PCR revealed that 18 (17.31%) and 6 (5.77%) imipenem(More)
Neonatal sepsis is a life-threatening emergency, and any delay in treatment may cause death. Because of the importance of the problem in Iran, the aim of this retrospective study was to determine the etiological agents of neonatal septicemia, and the prevalence and epidemiology of Klebsiella bacteremia in the neonatal wards. Two hundred and ten cases of(More)
Recent data indicates an increasing rate of vancomycin resistance in clinical enterococcal isolates worldwide. The nosocomial enterococci are likely to harbor virulence elements that increase their ability to colonize hospitalized patients. The aim of this study was to characterize virulence determinants in vancomycin-resistant enterococci (VRE) obtained(More)
BACKGROUND AND OBJECTIVES Pseudomonas aeruginosa is one of the most important causative agents of nosocomial infections especially in ICU and burn units. P. aeruginosa infections are normally difficult to eradicate due to acquired resistance to many antibiotics. Recent appearance of carbapenem resistant P. aeruginosa isolates is considered a major(More)

Meningitis is one of the hazardous and life threatening infections and is associated with mortality and morbidity. The aim of this study was to determine etiological agents of childhood bacterial meningitis. The culture, Gram staining, agglutination and PCR assays were used to examine CSF specimens from 277 patients with presumed bacterial meningitis for(More)
AIM The aim of this study was to investigate anaerobic and aerobic bacteria profile and determination of antibiotic susceptibility pattern in aerobic bacteria. METHOD Specimens were cultured using optimal aerobic and anaerobic microbiological techniques. Identification of bacterial isolates was performed by standard microbiological methods and antibiotic(More)
