Community-associated methicillin-resistant staphylococcus aureus epidemic clone USA100; more than a nosocomial pathogen
نویسنده
چکیده
BACKGROUND We characterized 100 USA100 epidemic MRSA from individuals in the community with no known healthcare-associated risk factors. FINDINGS Molecular epidemiology demonstrated 21 pulsed-field types and six spa types. SCCmec typing demonstrated that all of the strains possess the type II cassette. The staphylococcal enterotoxin D virulence gene was also present. CONCLUSION Characterization of USA100 MRSA in the community illustrated the importance of nasal carriage, and the genetic diversity of the USA100 clone.

Methicillin-resistant Staphylococcus aureus is an established nosocomial pathogen (HA-MRSA, hospital acquired MRSA), but has recently begun to appear in the community (CA-MRSA, community acquired MRSA). The cause of resistance to methicillin and all other beta-lactam antibiotics is the mecA gene, which is situated on a mobile genetic element, the Staphylococcal Cassette Chromosome mec (SCCmec)....

Background: Staphylococcus aureus is one of the most common causes of nosocomial infections with high morbidity and mortality rate. Traditionally, methicillin resistant staphylococcus aureus has been considered a major nosocomial pathogen in healthcare facilities, but in the past decade, it has been observed emerging in the community as well. Informations regarding hospital microbial colonizati...

Background & Aims: Methicillin-resistant Staphylococcus aureus (MRSA) is a major nosocomial pathogen worldwide. The aim of this study was to determine the risk factors of nasal carriage of MRSA and its antibiotic susceptibility pattern among healthcare workers at Namazi Hospital (Shiraz-Iran) Methods: In a cross-sectional study from July to November 2006, nasal swabs were taken from 600 stratif...

Background & Aims: Prevalence of community and hospital acquired methicillin-resistant Staphylococcus aureus (MRSA) infection is increasing. The primary reservoir is the anterior nares; and nasal carriage is a risk factor for infection in a variety of populations. Infection due to hospital-acquired colonization is different from community acquired in clinical manifestations and antibiotics susc...

Oxacillin-resistant Staphylococcus aureus (ORSA) is a virulent pathogen responsible for both health care-associated and community onset disease. We used SmaI-digested genomic DNA separated by pulsed-field gel electrophoresis (PFGE) to characterize 957 S. aureus isolates and establish a database of PFGE patterns. In addition to PFGE patterns of U.S. strains, the database contains patterns of rep...
