title: [Severe Legionella pneumopathy in an immunologically normal infant].
abstract: A case of legionnaires' disease is described in a 9 months old boy. He had a rapidly extensive bilateral pneumoniae. There was no premorbidity. The diagnosis was made by demonstrating legionella pneumophila serogroup 1 in pulmonary biopsy and pleural liquid, by direct immunofluorescence assay and positive culture. There was no seroconversion. An adenovirus type 2 was also isolated in pulmonary biopsy, with an strong seroconversion. The course was favorable, with Doxycycline therapy.
