Abstract:
Two patients with pneumonitis due to legionellosis are described. The etiologic diagnosis was based on high titers of immunoglobulin (Ig)M class antibodies (1/2048 and 1/512) detected by indirect immunofluorescence. The etiologic agents were presumed to be Legionella bozemanii in one case and either L. bozemanii or L. longbeachae in the other. Both patients made an uneventful recovery. Infections with these organisms have not been described in Israel previously.
