Taenia solium, also known as Taenia solium, Taenia solium or Taenia solium, is the main human parasitic tapeworm in China. In ancient medical books, it was called inchworm or white worm. As early as 2 17 AD, there was a record of white striped worm in synopsis of golden chamber. In 6 10 AD, Chao Fangyuan described the worm as "an inch long, white, with a small flat shape" and pointed out that it was infected by eating meat.
China recorded three kinds of herbs to drive white worms in Shennong Herbal Classic. As early as 1558, Rumber discovered human cysticercosis, and Kuchemeister and Leuchart confirmed the relationship between cysticercosis and human adults respectively.
Second, schistosomiasis?
Schistosoma japonicum is completely parasitic, most of which are parasitic in the camp and a few are parasitic outside the camp. The hermaphroditic Schistosoma japonicum is parasitic in venous vessels of mammals in a folded state. There are seven development stages in the life history process: adult, egg, miracidium, female metacercariae, ascocystis, cercaria and larva.
Among them, cercaria is the infection stage; Cercariae, larvae, adults and eggs can all cause diseases, but eggs are the most important pathogenic stage, and egg granuloma and fibrosis caused by their deposition in liver, intestine, bladder and reproductive organs are the most important pathological changes of schistosomiasis. Diagnosis can be made by detecting eggs in feces or urine and intestinal tissue. The therapeutic drug is praziquantel.
Among the six kinds of schistosomiasis parasitic on human body, Schistosoma aegypti, Schistosoma mansoni and Schistosoma japonicum are widely distributed and seriously harmful. Only Schistosoma japonicum has been found in China, and Oncomelania hupensis is the only intermediate host, which is distributed in the Yangtze River basin and 12 provinces, municipalities and autonomous regions south of it. Controlling the source of infection is the basis of comprehensive control strategy.

Clonorchis sinensis (Cobbold, 1875) Looss, 1907, also known as clonorchis sinensis and leech. Adult parasites in human hepatobiliary duct can cause clonorchiasis, also known as liver fluke disease.
This worm was first discovered in the bile duct of an overseas Chinese in Kolkata in 1875, and was diagnosed in China in 1908. 1975, the eggs of this insect were found in the feces of the ancient corpse of the Western Han Dynasty in Jiangling, Hubei, China, and later in the ancient corpse of the Chu Tomb of the Warring States Period in this county, thus proving that clonorchiasis has existed in China for at least 2300 years.
5. Sheep liver leech?
Leech belongs to Platycladus orientalis, Trematoda and Metazoa, also known as Fasciola hepatica.
The biggest parasite is Fasciola brucei, not Fasciola hepatica (leech).
Hirudin is a small flatworm with a body length of about 2 cm, which feeds on the blood or body of the host. It often attacks cattle and sheep, spreads diseases and brings serious diseases to human beings.
