Endoscopic and pathology images: (a) Many white and transparent curved parasites, shaped like a riding crop and adsorbed on the colon wall, inducing hyperemic and edematous mucosa (black arrow). (b) The parasites were concentrated in the ascending colon (black arrow). (c) The male mature trichurid (black arrow) and a large number of fusiform eggs in the female trichurid body could be seen (inside the box) (hematoxylin and eosin staining, x40, scale bar: 500 mum). The thick egg shells and a plug at both ends were consistent with trichurid egg (bottom right) (H&E staining, x200).

The white-striped parasites adsorbed on the colon wall could not be washed away easily (Fig. 1a). In the right colon, a large number of parasites had gathered, and the colon mucosa was slightly pale, accompanied by patchy hyperemia, edema, and erosion, which was consistent with parasitic colitis (Fig. 1b). The thick eggshells and a plug at both ends were consistent with trichurid egg (Fig. 1c).
