Comparison of the microagglutination test with bactericidal response to Legionella pneumophila (Legionnaires disease bacterium).
This investigation found that individuals with microagglutination antibody titers of 1:32 or greater to Legionella pneumophila produced bactericidal activity against the bacterium. Those individuals with microagglutination antibody titers of 1:16 or less demonstrated no bactericidal activity.
