biostudies-literatureUnknown7Wang HCommunity-acquired pneumonia (CAP) is a worldwide infectious disease caused by bacteria, viruses, or a combination of these infectious agents. <i>Mycoplasma pneumoniae</i> is an atypical pneumonia pathogen that causes high morbidity and mortality in children, and adenovirus can lead to severe pneumonia. However, the etiology of different types of pneumonia is still unclear. In this study, we selected a total of 52 inpatients with <i>M. pneumoniae</i> pneumonia (MPP) (<i>n</i> = 21), adenovirus pneumonia (AVP) (<i>n</i> = 16), or tracheomalacia (<i>n</i> = 15) to serve as a disease control. Bronchoalveolar lavage fluid (BALF) samples that had been obtained for clinical use were analyzed.
