We report a rare case of lung abscess due to . In this case, an analysis of the aspirate from frank pus revealed Gram-positive coccobacilli. We initially strongly suspected lung abscess associated with actinomycosis because of the chronic/recurrent clinical course and radio-pathological findings such as a granuloma lesion. Although a biochemical analysis revealed sp., 16S rRNA gene sequencing and a phylogenetic tree analysis of the isolated strain confirmed the presence of . Some cases previously diagnosed as actinomycosis might be correctly diagnosed as infection. Clinicians should be aware that additional studies using 16S rRNA gene sequencing are needed to clarify whether pulmonary infection associated with is a similar entity to that of chronic granulomatous infection disease in pulmonary actinomycosis.
我们报告了一例罕见的由……引起的肺脓肿病例。在此病例中，对来自脓性分泌物的抽吸物分析显示为革兰氏阳性球杆菌。由于慢性/复发性临床病程以及肉芽肿病变等放射病理学表现，我们最初强烈怀疑与放线菌病相关的肺脓肿。尽管生化分析显示为……菌属，但对分离菌株进行的16S rRNA基因测序和系统发育树分析证实了……菌的存在。一些先前诊断为放线菌病的病例可能被正确诊断为……菌感染。临床医生应意识到，需要使用16S rRNA基因测序进行更多研究，以明确与……菌相关的肺部感染是否与肺放线菌病中的慢性肉芽肿性感染疾病类似。
