Lack of evidence for persistent nasal colonization with community-acquired methicillin-resistant Staphylococcus aureus in a central European cohort.

摘要

One hundred and three patients who had previously tested positive for community-acquired methicillin-resistant Staphylococcus aureus (cMRSA) were followed up for a mean time of 32.6 months. Eighty patients had a history of skin or soft tissue infection, and the remainder were mostly asymptomatic carriers. Of 103 patients, only two reported ongoing symptoms with abscess formation. Of 81 nasal swabs available, 30.9% were positive for S. aureus but only four yielded Panton-Valentine leukocidin-positive methicillin-resistant S. aureus. In summary, we were unable to find persistent health issues or nasal colonization with cMRSA in a cohort of previously cMRSA-infected/colonized patients.
