摘要
We investigated nasopharyngeal carriage of Streptococcus pneumoniae and Staphylococcus aureus among infants and young children with acute otitis media in a country where use of 7-valent pneumococcal conjugate vaccine (PCV7) has been progressively implemented. Among 1783 children enrolled, 60.8% carried S. pneumoniae, and 9% carried S. aureus. Among S. pneumoniae carriers, the rate of S. aureus carriage was 8.4%, compared with 9.9% among S. pneumoniae noncarriers. The rate of S. pneumoniae carriage in the PCV7-vaccinated population was lower (59.8%) than that observed in the nonvaccinated population (66.2%; P <.04). In contrast, in young children (age, < 2 years) with acute otitis media, our study suggests that the S. aureus carriage rate is not affected by PCV7 immunization (9.0% in vaccinated children vs. 8.7% in nonvaccinated children). Furthermore, in children aged > 1 year, the booster dose induces a sharp reduction in the carriage of vaccine serotypes of S. pneumoniae, without any change in S. aureus carriage.
