On the basis of the ratio of the size of the Metagonimiasis is caused by trematode parasites occurring mainly in Korea, China, Taiwan, Japan, and Russia. F buski is the largest intestinal trematode, measuring 2-8 cm long by 1-2 cm wide, while the smallest intestinal trematodes are H heterophyes and M yokogawai, measuring less than 0. In this study, we … Similarly, Metagonimus yokogawai is an important food-borne trematode that causes metagonimiasis in China, Japan, Korea and Taiwan (Chai and Lee, 2002). Flukes of Metagonimus are characterized by the presence of a small submedian and unarmed ventral sucker; they differ from Heterophyes in lacking a genital sucker and gonotyl and from Haplorchis in having two testes (Chai, 2007, Chai, 2017).
