Other Legionella sp, especially
If available, nucleic acid probe after PCR amplification is rapid and sensitive for the detection of Legionella pneumophilla.
Other tests include Legionella spp antigen (DFA), Sputum microscopy and culture (special media); Legionella pneumophila type 1 antigen - urine.
For retrospective diagnosis, Legionella spp antibodies.
'Pontiac' fever, especially
An acute, self-limiting influenza-like illness (without pneumonia) of short (1 week) duration.
Often only suspected in epidemics of unexplained fever.
