title: Methicillin-resistant Staphylococcus aureus colonization in nursing home residents: a prevalence study in Northamptonshire.
abstract: A prevalence study of methicillin-resistant Staphylococcus aureus (MRSA) colonization was carried out in 17 nursing homes in Northamptonshire over a 20-month period. Thirteen of 275 residents swabbed (4.7%) were found to be colonized and six of the 17 homes (35%) had colonized residents. Only two homes had more than one colonized resident. Individual risk factors for colonization were gender (male) and the presence of skin ulcers and sores. There were no significant risk factors identified for homes. Spread may have occurred in the two homes which had more than one colonized resident. Both these homes had the epidemic strain EMRSA-15 whereas three of the four homes with a single colonized resident had EMRSA-16. It is suggested that homes with residents colonized with EMRSA-16 may be able to prevent spread by adherence to good infection control procedures but that this may not be adequate to prevent spread of EMRSA-15.
