Two case-control studies evaluated the prevalence of community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) carriage at hospital admission and characteristics of patients with CA-MRSA. Among 14,253 patients, CA-MRSA prevalence was 0.9/1,000 admissions. Although 5 CA-MRSA isolates contained Panton-Valentine leukocidin, only 1 patient had a previous skin infection. No easily m...

An intensive care nurse with eczema was repeatedly treated for methicillin-resistant Staphylococcus aureus (MRSA) carriage. Because cultures remained positive for MRSA, her house was investigated. Thirty-four percent of environmental samples yielded MRSA. Her children and cat were free of MRSA. The house was decontaminated with gaseous ozone. All subsequent cultures were negative for MRSA. This...

M ethicillin-resistant Staphylococcus aureus (MRSA) is an everincreasing problem facing the health service in the U.K. There is a need to develop new methods of combating MRSA. In the Manchester diabetic foot clinic, the prevalence of MRSA is 40% of staphylococcal cultures. MRSA has been demonstrated to double the foot ulcer healing time (1). While the pathogenetic relevance of MRSA colonizatio...

In this study we investigated the kinetics of colonization, the host susceptibility and transmissibility of methicillin-resistant Staphylococcus aureus (MRSA) after nasal treatment of pigs with three different MRSA strains of distinctive clonal lineages (sequence type 398 [ST398], ST8, and ST9), and origin in weaning piglets. The colonization dose of 5.0 × 10(8) CFU/animal was determined in pre...

Methicillin-resistant Staphylococcus aureus (MRSA) is a pervasive healthcare-acquired (HA) pathogen with recent emergence as a community-acquired (CA) pathogen. To elucidate whether meat mediates MRSA transmission between animals and humans in Japan, this study examined MRSA isolates from retail meat (n = 8), cows with mastitis (n = 7), and humans (HA-MRSA = 46 and CA-MRSA = 54) by molecular ty...

Increasing reports of the appearance of novel nonmultiresistant methicillin-resistant Staphylococcus aureus MRSA (MRSA) strains in the community and of the spread of hospital MRSA strains into the community are cause for public health concern. We conducted two national surveys of unique isolates of S. aureus from clinical specimens collected from nonhospitalized patients commencing in 2000 and ...

INTRODUCTION Methicillin-resistant Staphylococcus areus (MRSA) is an emerging problem. The Danish Health and Medicines Authority (HMA) has developed a question-based screening tool to identify patients with MRSA. The tool has three parts: questions on general risk situations, special risk situations and individual risk factors. The emergency departments (ED) play a key role in the prevention of...

BACKGROUND HIV-infected persons have increased risk of MRSA colonization and skin and soft-tissue infections (SSTI). However, no large clinical trial has examined the utility of decolonization procedures in reducing MRSA colonization or infection among community-dwelling HIV-infected persons. METHODS 550 HIV-infected adults at four geographically diverse US military HIV clinics were prospecti...

Staphylococcus aureus is responsible for a broad range of clinical infections, most notable of which are cases of bacteremia and endocarditis. Staphylococcus aureus is an important cause of serious infections in both hospitals and the community. Methicillin-resistant Staphylococcus aureus (MRSA) were first reported in 1961 and the first hospital outbreak of MRSA was reported in 1963. When MRSA ...
