The bacterial species in the Streptococcus anginosus group (S. constellatus, S. anginosus, S. intermedius) are important causative pathogens of bacterial pneumonia, pulmonary abscesses and empyema. However, the bacteria in this group are primarily oral resident bacteria and unable to grow significantly on ordinary aerobic culture media. We experienced a case of pneumonia and empyema caused by Streptococcus intermedius detected using a 16S rRNA gene sequencing analysis of bronchoalveolar lavage fluid and pleural effusion, but not sputum. Even when applying the molecular method, sputum samples are occasionally unsuitable for identifying the causative pathogens of lower respiratory tract infections.
