Carriage of Methicillin-Resistant Staphylococci and Their SCCmec Types in a Long-Term-Care Facility ▿
Following an outbreak caused by staphylococcal cassette chromosome mec (SCCmec) type V methicillin (meticillin)-resistant Staphylococcus aureus (MRSA), a point-prevalence survey of the nasal carriage of staphylococci was conducted in a long-term-care facility in northern Finland in 2004. The focus w...
