title: Atypical legionellosis: isolation of Legionella pneumophila serogroup 1 from a patient with aspiration pneumonia.
abstract: It has been suspected that the number of Legionella pneumophila infections is substantially higher than commonly reported, due to subclinical infections. We report a patient where the diagnosis of a legionella infection was made only because of a large-scale surveillance programme for legionellosis. The case demonstrates the possibility of legionellas being involved in lung disease though not necessarily causing overt legionellosis.
