Figure 1

Electron micrographs of D562 epithelial cells incubated with TIGR4 and G54 strains for 2 hours. Pneumococci attach to the host cells either as micro-colonies (A - TIGR4) or single colonies (B, D - TIGR4, C (including inset) - G54) and are surrounded by host pseudopodia. Bacteria invade host cells and are internalized into cytoplasmic vacuoles (E - TIGR4 and F - G54). Original magnifications A, 4400X; B, 4400X; C, 4400X (inset, 15000X); D, 26000X; E, 3200X; F, 1650X (inset, 6500X).
