MALADIE DU LEGIONNAIRE CONTRACTEE A BRUXELLES. UNE OBSERVATION

: A 71-year-old patient living in a street where major road works were taking place developed diffuse bronchopneumonia with changes in hepatic and renal biochemical tests. Since neutrophilia was moderate and all bacteriological investigations were negative, the patient was given erythromycin and was tested for antibodies directed against Legionella pneumophila. The titers of these antibodies rose from 32 to 2048 after one month. The patient was cured.
