Trematode

It includes two groups of parasitic flatworms, known as flukes. They are internal parasites of molluscs and vertebrates. Most trematodes have a complex life cycle with at least two hosts. The primary host, where the flukes sexually reproduce, is a vertebrate. Cercaria is also a synonym for Euglena.

The flukes, or trematodes , are long-lived parasites that can cause human disease by mechanical obstruction and by inciting local inflammatory responses in affected organs (Table 4).

Blood flukes (Schistosoma spp.), hepatobiliary flukes (Clonorchis sinensis, Opisthorchis spp., and Fasciola hepatica), and lung flukes . Trematode infections occur worldwide. Foodborne trematode infections, or foodborne trematodiases, are a group of parasitic infections caused by trematodes (flatworms or “flukes”). These organisms are divided into four groups on the basis of their final habitats in humans: (1) the hermaphroditic liver . Infect Dis Clin North Am.

Phylum Platyhelminthes, commonly called flatworms, is comprised of four groups: (1) turbellarians, (2) trematodes , (3) monogeneans, and (4) cestodes. Therefore, a knowledge of the biology of the intermediate host as well as of the definitive host is essential in understanding modes of transmission and devising effective control measures. The trematodes are distinguished by their holdfasts resembling suckers that aid them to anchor . Furthermore, dynamics of transmission of trematode.
