Growth of L. pneumophila in U937 human monocytic cells. Differentiated U937 cells (1 × 106 cells/well) were infected with approximately 1 × 106 bacteria/well for 1 h. The data shown are representative of those from three experiments, which showed similar results. Error bars indicate the standard errors of the mean. The growth rates of 80-045 (squares) and LAM0101 (circles) at 0, 24, and 48 h after infection showed no significant difference.
