英文摘要 | Background: We previously reported the incidence of community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) infections among children in Taiwan was increasing. This study examined the extent of MRSA colonization in the healthy pediatric population existed in parallel with this trend. Method: In this prospective observational study, nasal swabs were obtained from healthy children presenting for child healthcare visits or attending one of seven kindergartens during a 2-year period. A case-control study and molecular typing studies were performed. Results: Of 1195 children, 89 (7.4%) had nares cultures positive for MRSA. Risk factors for MRSA colonization included household contact with a high-risk individual (odds ratio [OR], 8.971; 95% confi dence interval [CI], 2.968-27.117) and recent antibiotic use (OR, 5.997; 95% CI, 3.605-9.976). Staphylococcal cassette chromosome mec (SCCmec) typing showed most community MRSA strains were SCCmec types IV and type V(subscript T). Pulsed-field gel electrophoresis revealed MRSA clones distinct from nosocomial MRSA isolates have disseminated in healthy children, and Panton-Valentine leukocidin genes were present in 15 of 89 MRSA isolates (16.9%). Conclusions: As colonization typically precedes infection, the characteristics of children with MRSA nasal carriage may be useful for distinguishing those who may be at risk of MRSA infection. |
