title: Legionella pneumophila serogroup 12 isolated from human and environmental sources.
abstract: A Legionella-like organism (strain 570-CO-H [= ATCC 43290]) isolated from the lung tissue of a patient with pneumonia was shown by growth, as well as physiological, serological, and genetic characteristics, to belong to a new Legionella pneumophila serogroup, serogroup 12. Two additional strains were detected with antiserum specific for strain 570-CO-H. These strains were isolated from environmental sources.
