Figure 1. Scanning electron microscopy images of A) an egg of the Ecuadorian Amphimerus spp. trematode (original magnification ×3) obtained from a human and B) an egg of the Asian Clonorchis sinensis trematode (original magnification ×4). Although the size is similar, the pattern of the surface is different, thus differentiating the 2 genera.
