RESUMO
Electron microscopic observations were carried out to confirm the presence of surface projections on Chlamydia psittaci reticulate bodies (RBs). The morphology of the projections on RBs was identical with that on elementary bodies (EBs); one end of each projection was connected with the cytoplasmic membrane, but the other end of the projection protruded beyond the cell wall through a fine hole or rosette in the cell wall. The results demonstrated that the rosettes seen in RB cell walls were morphological markers indicating the presence of the surface projections. A statistical anaylsis of the number of projections on EBs and the number of rosettes in RB cell walls prepared at 10, 15, and 20 h after infection demonstrated that all RBs had the projections and that the number of projections was maximal by 10 h after infection and then decreased gradually to approximately the same number of projections on EBs.
