Fig. 1. Representative images, captured by the KU-F40 system, of the organisms identified differently by the FECT system. (A) Metagonimus yokogawai (FECT) vs. Clonorchis sinensis (KU-F40); (B) Trichuris trichiura (FECT) vs. Ascaris lumbricoides (KU-F40); (C) Entamoeba histolytica (FECT) vs. Blastocystis hominis (KU-F40); (D) Entamoeba histolytica (FECT) vs. Entamoeba coli (KU-F40); (E) Not detected (FECT) vs. Clonorchis sinensis (KU-F40). Images (A), (B), and (E) were captured using a 20× objective lens, while images (C) and (D) were captured using a 40× objective lens. FECT, formalin–ether concentration technique.
