Clonorchis sinensis under a light microscope: Notice the uterus; this species is monoecious. An adult C. sinensis is a flattened (dorsoventrally) and leaf-shaped fluke. The body is slightly elongated and slender, measuring 15–20 mm in length and 3–4 mm in width. [ 10 ]
Much of what is presently known about Dicrocoelium dendriticum is the result of the work of the naturalist Wendell Krull. [2] While D. dendriticum was discovered by Rudolphi in 1819 and D. hospes was discovered by Loos in 1899, the full life cycle was not known until Krull and C.R. Mapes published a series of papers from 1951-1953 detailing their observations and experiments.
Clonorchis sinensis is a trematode (fluke) which is part of the phylum Platyhelminthes. The parasitic worm is as long as 10 to 25 mm and lives in the bile ducts of the liver. It is a hermaphroditic fluke that requires two intermediate hosts. The eggs of the worms are passed in fecal matter into a body of water and are then ingested by mollusks.
Microscopic identification of eggs, or more rarely of the adult flukes, in the stool or vomitus is the basis of specific diagnosis. The eggs are indistinguishable from those of the very closely related Fasciola hepatica liver fluke, but that is largely inconsequential since treatment is essentially identical for both.
There are three main kinds of parasites: Clonorchis sinensis (a trematode/fluke), Anisakis (a nematode/roundworm) and Diphyllobothrium (a cestode/tapeworm). Infection by the fish tapeworm Diphyllobothrium latum is seen in countries where people eat raw or undercooked fish, such as some countries in Asia, Eastern Europe, Scandinavia, Africa, and ...
Elon Musk speaks with U.S. President-elect Donald Trump at a viewing of the launch of the sixth test flight of the SpaceX Starship rocket on November 19, 2024 in Brownsville, Texas.
Specific helminths can be identified through microscopic examination of their eggs (ova) found in faecal samples. The number of eggs is measured in units of eggs per gram . [ 35 ] However, it does not quantify mixed infections , and in practice, is inaccurate for quantifying the eggs of schistosomes and soil-transmitted helminths. [ 36 ]
