<b>Molecular etiological profile of atypical bacterial pathogens, viruses and coinfections among infants and children with community acquired pneumonia admitted to a national hospital in Lima, Peru.<br></b><b>Abstract</b> <b>Objetive: </b>The main objective of this study was to detect the presence of 14 respiratory viruses and atypical bacteria (<i>Mycoplasma pneumoniae, Chlamydia pneumoniae</i>), via Polymerase Chain Reaction in patients under 18 years old hospitalized due to CAP from Lima, Peru. <b>Results:</b> Atypical pathogens were detected in 39.73% (58/146); viral etiologies in 35.62% (52/146) and coinfections in 18.49% (27/146). The most common etiological agent was<i> M. pneumoniae</i> (n=47), followed by <i>C. pneumoniae</i> (n=11). The most frequent respiratory viruses detected were: respiratory syncytial virus A (n= 35), influenza virus C (n= 21) and parainfluenza virus (n= 10). Viral-bacterial and bacterium-bacterium coinfections were found in 27 cases. In our study population, atypical bacteria (39.73%) were detected as frequently as respiratory viruses (35.62%). The presence of <i>M. pneumoniae</i> and <i>C. pneumoniae</i> should not be underestimated as they can be commonly isolated in Peruvian children with CAP.

<b>秘鲁利马国家级医院收治的社区获得性肺炎（Community Acquired Pneumonia, CAP）患儿中非典型细菌性病原体、病毒及混合感染的分子病原学特征</b><br><b>摘要</b> <b>研究目的：</b>本研究旨在通过聚合酶链反应（Polymerase Chain Reaction, PCR），检测秘鲁利马因社区获得性肺炎住院的18岁以下患者体内14种呼吸道病毒以及非典型细菌（肺炎支原体（Mycoplasma pneumoniae）、肺炎衣原体（Chlamydia pneumoniae））的存在情况。<b>研究结果：</b>非典型病原体检出率为39.73%（58/146），病毒病原体检出率为35.62%（52/146），混合感染率为18.49%（27/146）。最常见的病原体检出物为肺炎支原体（n=47），其次为肺炎衣原体（n=11）。检出频率最高的呼吸道病毒依次为呼吸道合胞病毒A型（n=35）、丙型流感病毒（n=21）及副流感病毒（n=10）。共检出27例病毒-细菌及细菌-细菌混合感染病例。在本次研究人群中，非典型细菌（39.73%）的检出率与呼吸道病毒（35.62%）相当。肺炎支原体与肺炎衣原体的感染不应被低估，因其在秘鲁社区获得性肺炎患儿中较为常见。
