Metagonimus takahashii Suzuki, 1930

This parasite is very similar to Metagonimus yokogawai. The egg of Metagonimus takahashii in the stool is larger than that of M. yokogawai; that of M. takahashii is 28.5 to 34 µm by 17.5 to 20.5 µm. Also, the cercaria is larger, and the second intermediate hosts are carp rather than the fish used by M. yokogawai. Cats, dogs, and human beings have been naturally infected with this parasite.
