ABSTRACT
A 76-year-old man with periodontal disease was admitted to our hospital because of haemoptysis. His chest CT revealed a tumor in the right S10. Gram-negative rods were isolated from the aspiration specimen by CT-guided percutaneous needle aspiration. Aggregatibacter aphrophilus was identified using 16S rRNA gene analysis. He was diagnosed with lung abscess caused by A. aphrophilus, and the abscess was improved gradually with antibiotic treatment. Respiratory infection caused by A. aphrophilus is rare, and to our knowledge only 13 cases of pulmonary infection by this organism have been reported in the English literature, and this is the first case report in Japan.
