We analyzed a representative sample of methicillin-resistant Staphylococcus aureus (MRSA) from 11 European countries (referred to as the HARMONY collection) using three molecular typing methods used within the HARMONY group to examine their usefulness for large, multicenter MRSA surveillance networks that use these different laboratory methodologies. MRSA isolates were collected based on their ...
BACKGROUND Panton-Valentine leukocidin (PVL) is a gamma-toxin produced by Staphylococcus aureus encoded by genes lukS/lukF-PV with several single-nucleotide polymorphisms. A mutation at nucleotide position 527 results in substitution of histidine (H) to arginine (R) at amino acid 176. The groups defined based on the amino acid change, the "R isoform" group and the "H isoform" group. The purpose...
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 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 present investigation was undertaken to assess the proportion of methicillin-resistant Staphylococcus aureus (MRSA) strains among hospital-acquired isolates and to determine the clones of MRSA currently circulating in Poland by using a number of molecular techniques. Between January and May 2005, methicillin resistance was investigated among a total of 915 S. aureus isolates collected from ...
BACKGROUND Recent worldwide reports of community-onset skin abscesses, outbreaks of furunculosis, and severe pneumonia associated with methicillin-resistant Staphylococcus aureus (MRSA) carrying Panton-Valentine leukocidin (PVL) genes and the staphylococcal cassette chromosome mec (SCCmec) type IV indicate that MRSA infections are evolving into a community-related problem. The majority of cases...
BACKGROUND AND OBJECTIVES Methicillin-resistant S. aureus (MRSA) tends to be resistant to multiple antibiotics. Methicillin resistance is conferred by the acquisition of the mecA gene, which is carried by a mobile genetic element called the staphylococcal cassette chromosome mec (SCCmec). There are five major types of SCCmec elements (I-V). The majority of hospital-acquired MRSA (HA-MRSA) strai...
The risk factors for relapse of methicillin-resistant Staphylococcus aureus (MRSA) bacteremia after vancomycin treatment are unknown. Diversilab typing was used to classify recurrent bacteremia as relapse or reinfection. Bacteremia for >7 days and staphylococcal cassette chromosome mec element (SCCmec) type II were independently associated with relapse of MRSA bacteremia after vancomycin treatm...
OBJECTIVES Methicillin resistance in Staphylococcus aureus and coagulase-negative staphylococci (CoNS) is caused by expression of the low-affinity penicillin-binding protein (PBP) 2a encoded by the mecA gene. This gene is carried on the staphylococcal cassette chromosome mec (SCCmec) of which several types and subtypes have been described. CoNS and S. aureus share SCCmec types and it has been s...
Background and Objective: Methicillin resistant Staphylococcus aureus (MRSA), which is the most common cause of nosocomial infection, has been a major cause of morbidity and mortality around the world. This study was carried out to find out the resistance pattern and staphylococcal cassette chromosome mec (SCCmec) typing among MRSA. Materials and Methods: This descriptive work was done on 87 Me...
