A case of community-acquired pneumonia due to Legionella pneumophila serogroup 9 in which initial treatment with single-dose oral azithromycin appeared useful. Jpn J Infect Dis. 2017 Sep 11;: Authors: Ito A, Ishida T, Tachibana H, Ito Y, Takaiwa T, Fujii H, Hashimoto T, Nakajima H, Amemura-Maekawa J Abstract Legionella species are important causative pathogens for severe community-acquired pneumonia (CAP). Most cases of Legionella pneumonia are due to Legionella pneumophila serogroup 1, and CAP due to Legionella pneumophila serogroup 9 is rare. A fourth case of CAP due to Legionella pneumophila serogroup 9 is reported, and initial treatment using single-dose oral azithromycin appeared useful. Azithromycin injection or fluoroquinolone injection is usually recommended for the treatment of Legionella pneumonia, and no previous reports have shown the effectiveness of single-dose oral azithromycin. This case report is therefore valuable from the perspective of possible treatment for mild to moderate Legionella pneumonia using single-dose oral azithromycin.
