Abstract
Reported here is the case of a previously healthy 67-year-old man who was admitted to the intensive care unit with pneumonia caused by Legionella longbeachae. The organism was identified in sputum and serum by 16S rRNA-based PCR assay and sequence-based typing. One acute serum sample produced a single elevated IgM antibody titer of 1:512 against non-pneumophila Legionella spp. The patient fully recovered following the initiation of appropriate antibiotic treatment. Since most current laboratory tests for Legionella spp. cannot detect infections caused by non-pneumophila Legionella spp., culture on Legionella-selective media or PCR should be considered when diagnosing severe pneumonia of unknown etiology.Keywords
