Immunofluorescence microscopy of infected monocytes and monocyte-derived Dendritic cells (DCs). Monocytes (upper panel) and monocyte-derived DCs (lower panel) were infected with C. trachomatis serovars Ba, D and L2 (MOI-3) for 2 days. Chlamydial inclusions (green) were stained with FITC conjugated anti-chlamydia LPS antibody and counterstained with Evans Blue. Pictures were taken at 63X magnification with Leica DMLB. The figures are representative of 3 independent experiments.
