background klebsiella pneumoniae is a family member of enterobacteriaceae. isolates of k. pneumoniae produce enzymes that cause decomposition of third generation cephalosporins. these enzymes are known as extended-spectrum beta-lactamase (esbl). resistance of k. pneumoniae to beta-lactamase antibiotics is commonly mediated by beta-lactamase genes. objectives the aim of this study was to identif...

  Background and Objective: Urinary tract infection (UTIs) is one of the most common diagnosed infectious diseases. In order to determine the spectrum of bacterial etiology and antibiotic resistance pattern of the uropathogens that cause community acquired UTI, a retrospective study was performed in Research Center of Reference laboratories of Iran on urine samples of referred patients during ...

Objective(s) Staphylococcus aureus is a common cause of human infection, and emergence of vancomycin-resistance S. aureus  is a great concern for treatment of methicillin-resistant S. aureus,(MRSA) in recent years (MRSA). Here, we report the isolation of high-level VRSA. Materials and Methods S. aureus was isolated from foot ulcer of a diabetic woman in Tehran, Iran. Antibiotic susceptibilit...

conclusion a high rate of mrsa in both community- and hospital-acquired infections were observed. background staphylococcus aureus (s.aureus) is an importantpathogen in human infections.some strains of s.aureusare methicillin-resistant (mrsa) andcause hospital- and community-acquired infections in children. the aims of this study were to determine nasalcarriage rate of s. aureus and susceptibil...

background: the prevalence of antimicrobial resistance among enterobacteriaceae is increasing worldwide. identification of pathogens and their resistance to antimicrobials is mandatory for successful empiric antibiotic treatment. the aim of this study was to investigate the prevalence of antimicrobial resistance of enterobacteriaceae isolated from hospital-acquired and community-acquired infect...
