Some of them are Anisakis simplex, Pseudoterranova decipiens, Diphyllobothrium spp, Heterophyidae spp, Opisthorchiidae
(family of flatworms): In freshwater fish
Discovery of Opisthorchis lobatus (Trematoda: Opisthorchiidae
): new recorded species of small liver flukes in the greater Mekong sub-region.
These results indicated that the evolutionary relationship of P cervi was closer to other members of the Paramphistomatidae than to other families (Fasciolidae, Echinostomatidae, Dicrocoeliidae, Paragonimidae, and Opisthorchiidae
A opistorquiase e designacao dada as infeccoes humanas causadas por varias especies de trematodeos hepaticos da Familia Opisthorchiidae

Opisthorchis viverrini and Clonorchis sinensis are pathologically important members of the family Opisthorchiidae
. Chronic infections with these liver flukes closely associate with the development of the bile duct cancer (cholangiocarcinoma) and the liver cancer (hepatocarcinoma) in humans .
Up to 10 randomly selected metacercariae from each infected fish were identified to the species level, and the rest of the metacercariae were sorted into >1 type groups: liver flukes (Opisthorchiidae
), intestinal flukes (Heterophyidae), and nonzoonotic or dead metacercariae.
Although these digenetic trematodes of the Opisthorchiidae
family are closely related to the genera Clonorchis and Opisthorchis, there are morphologic differences.
To the Editor: Opisthorchis viverrini and Clonorchis sinensis, the 2 major species of small liver flukes (family Opisthorchiidae
), cause chronic inflammation in the bile duct, which leads to cholangitis and cirrhosis of the liver, and are a predisposing factor for cholangiocarcinoma (1).
PCR diagnosis of infections with different species of Opisthorchiidae
using a rapid clean-up procedure for stool samples and specific primers.
The FZTs include many species, especially representatives of the families Heterophyidae, Echinostomatidae, and Opisthorchiidae
. Although their metacercarial cysts are easily inactivated by heating at 60[degrees]C or freezing to -20[degrees]C, they are highly prevalent in many regions, especially in Asia where food traditions include eating raw or improperly cooked fish dishes (Figure 1) (4).
