[Models for the study of the toxic action of Legionella pneumophila].
L. pneumophila virulent culture and the filtrate of this culture disintegrated with ultrasound were shown to be toxic for guinea-pig peritoneal macrophages in vitro and for AKR mice. The virulent culture of this infective agent and the filtrate of the supernatant fluid obtained from the washings of its virulent culture had no toxic effect on a macrophage monolayer culture and on mice. The use of these models for characterizing Legionella intracellular toxic activity, as well as for characterizing Legionella strains isolated from patients and the environment, is proposed.
