摘要

摘要目的了解肺炎支原体肺炎(Mycoplasma pneumoniae pneumonia, MPP)是儿童社区获得性肺炎的重要组成部分,探讨新冠肺炎(COVID-19)暴发后肺炎支原体肺炎(Mycoplasma pneumoniae pneumonia, MPP)的流行病学和遗传学特征。方法收集2021年1月至2021年12月住院呼吸道感染患者咽拭子样本15538份。所有标本均采用实时逆转录聚合酶链反应(RT-PCR)检测。对阳性标本中肺炎支原体(MP) P1基因进行扩增和测序。结果2021年1月至2021年12月,本研究共对15538例急性呼吸道感染患儿进行实时RT-PCR检测,其中男生9056例,女生6482例。总体而言,469例(3.0%,469/15,538)MP检测呈阳性,其中男性266例(2.9%,266/9,056),女性203例(3.1%,203/6,482)(p = 0.48)。p < 0.05;1岁组、1 ~ 3岁组、3 ~ 5岁组、5 ~ 7岁组、7岁组分别为1.31%(85/ 6474)、1.87%(64/ 3423)、3.65%(95/ 2601)、8.02%(127/ 1583)、6.72%(98/ 1458)。24份MP阳性样品P1基因同源性分析显示,核苷酸序列一致性达91.2 ~ 99.3%。结论新冠肺炎疫情暴发后,5 ~ 7岁儿童MPP阳性检出率最高,中国杭州地区MPP基因型集中在P1亚型,即I型。

Epidemiological and Genetic Characteristics of Mycoplasma pneumoniae Pneumonia after the Outbreak of COVID-19
Abstract Objective Mycoplasma pneumoniae pneumonia (MPP) accounts for a major part of community-acquired pneumonia in children, and we performed this study to investigate the epidemiological and genetic characteristics of MPP after the outbreak of COVID-19. Methods A total of 15,538 throat swab samples were collected from inpatients with respiratory tract infections from January 2021 to December 2021. All specimens were detected by real-time reverse transcriptase polymerase chain reaction (RT-PCR). The P1 gene of Mycoplasma pneumoniae (MP) in positive samples was amplified and sequenced. Results From January 2021 to December 2021, a total of 15,538 children with acute respiratory tract infection were tested by real-time RT-PCR in our study, including 9,056 boys and 6,482 girls. Overall, 469 (3.0%, 469/15,538) tested positive for MP, with 266 (2.9%, 266/9,056) males and 203 (3.1%, 203/6,482) females (p = 0.48). The positive rates of MP infection in < 1 year old, 1 to 3 years old, 3 to 5 years old, 5 to 7 years old, and >7 years old groups were 1.31% (85/6,474), 1.87% (64/3,423), 3.65% (95/2,601), 8.02% (127/1,583), and 6.72% (98/1,458), respectively. The homology analysis of the P1 gene of 24 MP positive samples showed that the nucleotide sequence consistency was up to 91.2 to 99.3%. Conclusion After the outbreak of COVID-19, positive detection rate was the highest from 5 to 7 years old among children with MPP, and the genotype of MP in Hangzhou, China area was focused on P1 subtype, type I.
