title: Legionella pneumonia caused by Legionella pneumophila serogroup 2: second case report in Japan.
abstract: A 56-year-old man with a 3-day history of a chilly sensation and general fatigue presented to a hospital in his neighborhood. He was diagnosed as having pneumonia and immediately treated with intravenous ceftriaxone sodium, but his respiratory condition deteriorated and he developed symptoms of restlessness. Although Legionella urinary antigen detection tests were negative, his clinical course suggested Legionella pneumonia. After his treatment was changed to intravenous ciprofloxacin and oral clarithromycin, his general condition gradually improved. Later, Legionella pneumophila serogroup 2 was isolated from a bronchoalveolar lavage specimen. This was considered to be the causative organism. In our literature search, this was only the second case of Legionella pneumonia caused by Legionella pneumophila serogroup 2 in Japan.
