Mycoplasma pneumoniae and Chlamydophila pneumoniae are atypical bacteria that are frequently found in patients with asthma. A definitive diagnosis of infection is often difficult to obtain because of limitations with sampling and detection. Numerous animal studies have outlined mechanisms by which these infections may promote allergic lung inflammation and airway remodeling. In addition, there is mounting evidence from human studies suggesting that atypical bacterial infections contribute to asthma exacerbations, chronic asthma, and disease severity. The role of antimicrobials directed against atypical bacteria in asthma is still under investigation.
肺炎支原体和肺炎衣原体是常见于哮喘患者的非典型细菌。由于采样和检测的限制,通常难以明确诊断感染。许多动物研究已经概述了这些感染可能促进过敏性肺炎症和气道重塑的机制。此外,越来越多的来自人类研究的证据表明,非典型细菌感染会导致哮喘恶化、慢性哮喘和疾病严重程度增加。针对非典型细菌的抗生素在哮喘中的作用仍在研究中。
