Growth of Ab-opsonized C. burnetii in human macrophages. C. burnetii (Cb) were incubated with naïve or immune human sera, washed and added to cultures of human monocyte-derived macrophages. Bacterial genome equivalents in the culture were quantified at 0, 2, 4 and 6 days post-infection by qPCR. The results shown are from one experiment done in triplicate and representative of three independent experiments.
