Figure 5: Scanning electron microscopy of the interaction of A. polyphaga trophozoites with hamster cornea. In the first hours of coincubation areas of corneal injury were not observed. (a) After 16 h, only few regions of cellular disorganization and loss of the most superficial layers of the cornea were detected. Bar = 100 μm. (b) Trophozoite (T) was found in close relation with epithelial cells (arrow). Bar = 10 μm.
