INTRODUCTION Community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) infections are found with increasing the frequency, both in healthy individuals in the community and in hospitalized patients. In Colombia and the Andean region, CA-MRSA isolates have a genetic background that is related to the pandemic USA300 clone. OBJECTIVE Two molecular methods are designed and standardi...

BACKGROUND Staphylococcus aureus has been recognized as an important pathogen associated with inpatients and community infections. Community-acquired methicillin-resistant S. aureus (CA-MRSA) infections commonly present as skin and soft-tissue infections (SSTIs). Treatment often includes incision and drainage with or without adjunctive antibiotics. OBJECTIVES This study aimed to identify CA-M...

Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) has become a major problem in US hospitals already dealing with high levels of hospital-associated MRSA (HA-MRSA). Using antimicrobial drug susceptibility data for 1999-2006 from The Surveillance Network, we characterized the relationship between outpatient and inpatient levels of CA-MRSA nationally. In outpatients, the ...

BACKGROUND A new clone of community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA), sequence type (ST) 72-staphylococcal chromosomal cassette mec (SCCmec) type IV/IVA without the Panton-Valentine leucocidin (PVL) genes, has been the major clonal type in Korea since 2007. However, there have been no evaluations of the clinical features, risk factors and outcomes associated with C...

We examined trends in incidence of methicillin-resistant Staphylococcus aureus (MRSA) infections in Connecticut, with emphasis on 2007-2010, after legislation required reporting of hospital infections. A case was defined as isolation of MRSA from normally sterile body sites, classified after medical record review as hospital onset (HO), community onset, health care-associated community onset (H...

Meticillin-resistant Staphylococcus aureus (MRSA) is endemic in hospitals worldwide, and causes substantial morbidity and mortality. Health-care-associated MRSA infections arise in individuals with predisposing risk factors, such as surgery or presence of an indwelling medical device. By contrast, many community-associated MRSA (CA-MRSA) infections arise in otherwise healthy individuals who do ...

Osteomyelitis in adolescents is a serious disease with the potential for lifelong disability. The key to successful management is early diagnosis, including bone sampling for microbiological and pathological examination to allow targeted and long-lasting antibiotic therapy. Staphylococcus aureus is the most frequently isolated microorganism in these patients. Methicillin-resistant S. aureus (MR...

INTRODUCTION Methicillin-resistant Staphylococcus aureus (MRSA) is an important pathogen commonly associated with nosocomial infections. However, it has also been associated with community-acquired skin and soft tissue infections (CA-MRSA). There are few data on the identification and prevalence of CA-MRSA infections in Brazil. METHODS This is a cross-sectional study of 104 patients with comm...

The global spread of community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) since the mid-1990s is a major public health concern. The epidemiology of CA-MRSA differs from that of health-care-associated MRSA (HCA-MRSA), and this is reflected at the genetic level. Resistance to beta-lactams is encoded in the mecA gene, which is carried, along with resistance determinants for o...
