title: Failure to produce detectable antibodies to Legionella pneumophila by an immunocompetent adult.
abstract: A case of legionella pneumonia diagnosed by co-culture with amoebae and urinary antigen detection is described. Diagnostic antibody tests remained negative despite prolonged follow-up. Investigation showed no evidence of an under-lying immunodeficiency. The value of culture-based diagnosis and consequences of missed diagnoses are discussed.
