The carriage rate and serotype distribution of Streptococcus pneumoniae (S. pneumoniae) in a healthy population in China remains unclear. In this study, we collected the oropharyngeal swabs from 513 individuals in Xinjiang, China. Real-time PCR targeting the lytA gene and 12 serotypes were assessed to identify S. pneumoniae carriage. The total carriage rate of S. pneumoniae was 70.4% (361/513). The most prevalent serotypes were 19B/F, 18B/C, 5, and 6A/B. The highest carriage rate of S. pneumoniae was noted in children aged 6-10 years (88.6%), which merits further attention. The co-colonization rate of two or more S. pneumoniae serotypes was 79.8% (264/331). This study aimed to investigate the baseline pneumococcal carriage rate among healthy individuals in China to improve our understanding of the epidemiology of S. pneumoniae.
在中国健康人群中，肺炎链球菌（Streptococcus pneumoniae，S. pneumoniae）的携带率和血清型分布尚不清楚。本研究采集了中国新疆地区 513 名个体的咽拭子标本。采用针对 lytA 基因和 12 种血清型的实时 PCR 方法来鉴定 S. pneumoniae 的携带情况。S. pneumoniae 的总携带率为 70.4%（361/513）。最常见的血清型为 19B/F、18B/C、5 和 6A/B。6-10 岁儿童的 S. pneumoniae 携带率最高（88.6%），值得进一步关注。两种或多种 S. pneumoniae 血清型的共同定植率为 79.8%（264/331）。本研究旨在调查中国健康个体中肺炎链球菌的基线携带率，以加深我们对 S. pneumoniae 流行病学的认识。
