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 a 4...

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 susceptibility w...

background and objectives: the aim of the study was to determine the role and characteristics of nosocomial and community acquired staphylococcus sepsis in admitted children in tertiary centers in iran. patients and methods: a cross sectional descriptive-analytic study was performed since march 2008 to march 2009 in which all blood cultures from various admitted patients were checked for staphy...

background and objective: community-acquired methicillin-resistant staphylococcus aureus ( ca-mrsa) is increasingly reported worldwide. we aimed to determine the frequency of invasive ca-mrsa in children admitted to the pediatric wards of imam reza and ghaem hospitals of mashhad, iran. materials and methods: in this retrospective study, data regarding s. aureus isolates from pediatric patients’...

background: the emerge of rapid and accurate detection of meticillin-resistant staphylococcus aureus (mrsa) has been highlighted. objectives: the current study evaluated the prevalence of mec-a gene in biological specimens of various medical wards, in order to determine any possible relationship. patients and methods: using traditional culture methods, 250 isolates were detected. the prevalence...

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...

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...

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...

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...
