(A) Transmission Electron Microscopy of the intestinal epithelium of A. cantonensis. cross section of the intestinal epithelium showing a brush border composed of microvilli (Mi) and the presence of macrovesicles (red arrow) and microvesicles (blue arrow) of digestion; The epithelium is a multinucleate mosaic (N) or syncytium pattern showed no limit between these cells and the presence of basal lamina (BL); (B): The intestinal lumen is filled with a granular material, which sometimes contains a few intermixed membranous structures, vesicles and partially digested red blood cells (BC) originating from host blood feeding; (C): Transmission Electron Microscopy of the intestinal epithelium of A. cantonensis. The epithelial cells with microvilli (Mi), nuclei (N) and nucleolus (Nu) containing areas of loose and condensed chromatin. The presence of macrovesicles (larger arrow) and microvesicles (smaller arrow) of digestion; (D): Macrovesicles of digestion (red arrow) and short microvilli of different sizes.
