ABSTRACT
Opisthorchiasis is produced by two important species of Opisthorchis, namely, O. felineus (Rivolta, 1884) Blanchard, 1895 and O. viverrini (Poirier, 1886) Stiles and Hassall, 1896, both of which are cat liver flukes but which also infect certain other mammals and humans. As is the case with clonorchiasis, infection with opisthorchiasis is contracted through eating raw fish. Infected cats and dogs are usually found wherever Opisthorchis is endemic in human beings. In heavy infections with opisthorchiasis, worms are found in the gallbladder and pancreas. Treatment of opisthorchiasis has followed the path of treatment of clonorchiasis, and similar drugs have been tried for both; they include tartar emetic, gentian violet, gold salts, and fouadin, and they have been tested in experimental animals and in man. Other drugs used in the treatment of opisthorchiasis have been metronidazole, bitoscanate, and lucanthone hydrochloride. To a great extent control of opisthorchiasis is similar to that of clonorchiasis.
