Fig. 1. Transmission electron microscopy (TEM) of neutrophils with ingested bacteria and of isolated phagosomes. Neutrophils were allowed to phagocytose mycobacteria of the H37Rv strain or S. aureus, and the bacteria-laden phagosomes (MCPv and SCP, respectively) were subsequently isolated. The micrographs show a neutrophil after internalisation of H37Rv for 60 minutes (A); isolated MCPv devoid of contamination with other cellular organelles (B); individual MCPv (C); and individual SCP (D). N, stands for nucleus and the scale bars represent 1 µm (A,B) and 0.5 µm (C,D).
