Methicillin-resistant Staphylococcus aureus (MRSA) has recently emerged as a cause of community-acquired infections among individuals without risk factors. Community-associated MRSA (CA-MRSA) appears to be more virulent, causing superficial mild skin and soft tissue infections to severe necrotizing fasciitis, and in rare cases, pneumonia. Community-associated MRSA was first reported in Australi...

OBJECTIVES Staphylococcus aureus or methicillin-resistant Staphylococcus aureus (MRSA) has been an important pathogen causing bloodstream infections. Our study aimed to investigate the epidemiological and genetic diversity of clinical S. aureus isolates from patients with bloodstream infection in four hospitals of Shanghai from 2009 to 2011. METHODS A collection of S. aureus isolates causing ...

Although a relatively unspectacular, nonmotile coccus, Staphylococcus aureus is a dangerous pathogen and a major public health concern. In addition to being a common food-poisoning agent, it can cause serious skin and soft tissue infections and life-threatening diseases. Furthermore, resistance to multiple antibiotics, most notably to penicillin and methicillin, is common in S. aureus and makes...

Staphylococcus aureus, or methicillin-resistant S. aureus (MRSA), is a significant pathogen in both nosocomial and community infections. Community-associated MRSA (CA-MRSA) strains tend to be multi-drug resistant and to invade hospital settings. This study aimed to assess the antimicrobial resistance and molecular characteristicsof nasal S. aureus among newlyadmitted inpatients.In the present s...

Methicillin-resistant Staphylococcus aureus (MRSA) is classified as hospital associated (HA), community associated (CA), livestock associated (LA) and is a global concern. Developing countries, like India, are densely populated country challenging for public hygiene practices. HA-MRSA is comfortably recorded in India, and CA-MRSA is also reported as increasing one. CA-MRSA is serious disease wh...

INTRODUCTION Methicillin-resistant Staphylococcus aureus (MRSA) is a major cause of both hospital- and community-acquired infections worldwide. However, data about the molecular epidemiology of MRSA in North Africa are still scarce. METHODOLOGY All MRSA isolates recovered between January 2006 and July 2011 from one Algerian hospital were genetically and phenotypically characterized. RESULTS...

Introduction / objectives Methicillin-resistant Staphylococcus aureus (MRSA) is an increasing problem in the Americas and the Caribbean including Cuba. Recently, MRSA isolates are emerging as significant pathogens in the community. In the USA, the most prevalent community associated (CA-)MRSA clone is USA300 (ST8, spa type 008). Little is known about the molecular epidemiology of MRSA in some o...

Methicillin-resistant Staphylococcus aureus (MRSA) infections have been confined to healthcare centres for decades. However, MRSA infections are increasingly seen in young healthy individuals with no exposure to healthcare centres. These community-acquired MRSA (CA-MRSA) strains differ from healthcare-associated MRSA (HA-MRSA) strains in various ways. For example, CA-MRSA is strongly associated...

Methicillin-resistant Staphylococcus aureus (MRSA) is a leading cause of healthcare-associated infections and significant contributor to healthcare cost. Community-associated-MRSA (CA-MRSA) strains have now invaded healthcare settings. A convenience sample of 97 clinical MRSA isolates was obtained from seven hospitals during a one-week period in 2010. We employed a framework integrating Staphyl...

The number of infections attributable to community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) in Singapore is progressively increasing. Most cases in the past 2 years were caused by Panton-Valentine leukocidin-positive isolates belonging to sequence type 30, according to multilocus sequence typing. This has clearly become the predominant sequence type among CA-MRSA isolate...
