Rapid definitive diagnosis of Legionnaires' disease.
We describe a sporadic case of Legionnaires' disease in which the diagnosis was made by direct immunofluorescence of material obtained by percutaneous aspiration of the involved lung via a needle. Employment of this technique among selected patients with suspected Legionnaires' disease would provide for more rapid diagnosis and more prompt initiation of definitive therapy for some patients.
