title: Legionella pneumophila serogroup six: isolation from cases of legionellosis, identification by immunofluorescence staining, and immunological response to infection.
abstract: Isolates of Legionella pneumophila that are serologically different from strains of serogroups 1 through 5 were obtained from lung biopsy tissue or pleural fluid from three renal transplant recipients in Chicago, Ill. These strains were placed in a newly designated L. pneumophila serogroup, serogroup 6, on the basis of fluorescent-antibody staining characteristics. An L. pneumophila strain obtained from Bethesda, Md., one from Houston, Tex., and one from Oxford, England, also belong to this new serogroup. L. pneumophila serogroup 6 appears to be widely distributed geographically.
