It is commonly known as the Chinese water dragon, [2] [3] Indochinese water dragon, [4] [5] Asian water dragon, [6] [7] [5] Thai water dragon, [3] or green water dragon. [3] [5] Chinese water dragons are large diurnal lizards adapted for dense subtropical forests replete with unpolluted streams. They are semi-arboreal, roosting at night on ...
Schistosoma mansoni is a water-borne parasite of humans, and belongs to the group of blood flukes (Schistosoma). The adult lives in the blood vessels (mesenteric veins) near the human intestine. It causes intestinal schistosomiasis (similar to S. japonicum, S. mekongi, S. guineensis, and S. intercalatum). Clinical symptoms are caused by the eggs.
Microscopic identification of eggs in stool or urine is the most practical method for diagnosis. A stool examination should be performed when infection with S. mansoni or S. japonicum is suspected, and a urine examination should be performed if S. haematobium is suspected. Eggs can be present in the stool in infections with all Schistosoma ...
Routes of exposure and infection include ingestion of undercooked meat, drinking infected water, fecal–oral transmission and skin absorption. Some types of helminths and protozoa are classified as intestinal parasites that cause infection—those that reside in the intestines. These infections can damage or sicken the host (humans or other ...
These eggs have a strong shell that protects them against a range of environmental conditions. The eggs can therefore survive in the environment for many months or years. Many of the worms referred to as helminths are intestinal parasites. An infection by a helminth is known as helminthiasis, helminth infection, or intestinal worm infection ...
Immature, unembryonated eggs are discharged into the intestine and stool. In two weeks, eggs become embryonated in water, and after about seven weeks, tiny parasitic organisms called miracidia hatch from the eggs, which then go on to invade a suitable snail intermediate host.

The eggs look like other eggs from the family Taeniidae, so it is only possible to identify the eggs to the family, not to the species level. Since it is difficult to diagnose using eggs alone, looking at the scolex or the gravid proglottids can help identify it as Taenia saginata . [ 6 ]
