staphylococcus aureus causes a wide variety of infections worldwide. methicillin-resistant s. aureus is one of most common causes of nosocomial and community acquired infections. the fluoroquinolones are an important class of antibiotics that used to treat infections caused by s. aureus. today, a significant increase in the rate of ciprofloxacin resistance in methicillin-resistant s. aureus str...

background staphylococcus aureus is a major pathogen in hospital setting and in the community and causes a wide range of diseases. mrsa infection has recently become a serious problem in anti-microbial chemotherapy. the aim of the study was to detect and analyze the antibiotic diversity and isolation of methicillin resistance gene (meca) of s. aureus isolated from tehran hospitals as a rapid an...

conclusions the relative higher frequency of some virulence genes in this study may reflect the emergence of isolates containing these genes in shiraz medical centers. background staphylococcus aureus is amongst major human pathogens both in hospitals and the community. this bacterium is an opportunistic pathogen responsible for a large number of self-limiting and even life-threatening diseases...

background staphylococcus aureus is a common cause of infections among humans and animals and it is known as a community-acquired and nosocomial pathogen. most of the isolates contain lysogenic phages which are responsible for production of various virulence factors such as enterotoxins, staphylokinase, β-lysin, lipase, exfoliative toxin a and pantone-vlaentine leukociden (pvl). all staphylococ...

Background: Pseudomonas aeruginosa is the primary cause of infection with impaired defense mechanisms. P. aeruginosa commonly causes nosocomial infections and is the most common pathogen isolated from patients hospitalized for longer than 1 week. We examined the antimicrobial effect of multilayered carbon nanotubes on multi-drug-resistant. Materials and methods: In this research, 20 clinical i...

The emergence of nosocomial infections caused by CoNS has led clinicians and researchers to reconsider the role methicillin-resistant (MR-CoNS) as important agents infections. This study was conducted on clinical isolates MR-CoNS obtained from inpatients in Hospital Tengku Ampuan Afzan (HTAA) International Islamic University Malaysia Medical Center (IIUM-MC) determine their antimicrobial resist...

INTRODUCTION Community-acquired methicillin-resistant Staphylococcus aureus infections are a common, serious problem in pediatrics. OBJETIVE To describe antibiotic resistance in community-acquired Staphylococcus aureus (SA) bacteremias. To compare the characteristics of SA bacteremias in terms of methicillin resistance. MATERIALS AND METHODS Prospective cohort enrolled between January 2010 ...

OBJECTIVES Surveillance of hospital-acquired methicillin-resistant Staphylococcus aureus (HA-MRSA) infections has shown the emergence and spread of several epidemic MRSA clones over the past 10 years in Belgium. Whether these clones have been imported from abroad or else have arisen locally via staphylococcal cassette chromosome mec (SCCmec) acquisition by successful methicillin-susceptible S. ...

introduction : staphylococcus aureus colonization has been recognized as one of the most important risk factors for subsequent infections with this microorganism. in this study, we intended to identify all patients who were mrsa-positive upon admission and compare the prevalence of mrsa colonization on different days of study admitted in imam reza hospital in mashhad, iran. methods : this cross...
