Flatworm: From 2 Different Sources


Any species of worm that has a flattened shape.

Two types of flatworm are parasites of humans: cestodes (tapeworms) and trematodes (flukes, schistosomes; see liver fluke; schistosomiasis).

(platyhelminth) n. any of the flat-bodied worms, including the *flukes and *tapeworms. Both these groups contain many parasites of medical importance.

Cestoda

Tapeworms, which are segmented Platyhelminths (Flatworms) consisting, in their adult stage, of a scolex for attachment to the gut of the final host, an unsegmented neck region and a long segmented strobila consisting of immature, mature and gravid proglottids (segments).... cestoda

Flukes

Trematoda. Parasitic flatworms: (Fasciola hepatica) occurs mostly in sheep and in the freshwater snail. Larval forms of the latter encyst on water plants, commonly Watercress. On invasion into the human body, settles in the liver and bile duct.

Liquid Extract Butternut. 1:1 in 25 per cent alcohol BHP (1983), dose: 2-6ml, thrice daily.

Butternut. Powder, with few grains Cayenne. 750mg (three 00 capsules or half a teaspoon) thrice daily. Wormwood tea. 1-2 teaspoons to cup cold water steeped overnight. Consume on rising.

Molasses. Half a teaspoon Wormseed powder in a little molasses, night and morning, for 3 days, followed by laxative. For desperate cases.

Dandelion and Burdock, traditional drink. Freely. Diet. Strong Dandelion coffee. ... flukes

Liver Fluke

Any of various species of flukes (flatworms) that infest the bile ducts in the liver. The only significant fluke in the

is FASCIOLA HEPATICA, which causes the disease fascioliasis.

Fascioliasis has 2 stages. During the first stage, young flukes migrate through the liver, causing it to become tender and enlarged; other symptoms include

fever and night sweats. In the second stage, adult worms occupy the bile ducts. Their presence may lead to cholangitis and bile duct obstruction, which can cause jaundice. Treatment with an anthelmintic drug may be effective.... liver fluke

Fluke

n. any of the parasitic flatworms belonging to the group Trematoda. Adult flukes, which have suckers for attachment to their host, are parasites of humans, occurring in the liver (liver flukes; see Fasciola), lungs (see Paragonimus), gut (see Heterophyes), and blood vessels (blood flukes; see Schistosoma) and often cause serious disease. Eggs, passed out with the host’s stools, hatch into larvae called *miracidia, which penetrate an intermediate snail host. Miracidia give rise asexually to *redia larvae and finally *cercariae in the snail’s tissues. The released cercariae may enter a second intermediate host (such as a fish or crustacean); form a cyst (*metacercaria) on vegetation; or directly penetrate the human skin.... fluke

Platyhelminth

n. see flatworm.... platyhelminth

Tapeworm

(cestode) n. any of a group of flatworms that have a long thin ribbon-like body and live as parasites in the intestines of humans and other vertebrates. The body of a tapeworm consists of a head (scolex), a short neck, and a strobila made up of a chain of separate segments (proglottides). Mature proglottides, full of eggs, are released from the free end of the worm and pass out in the host’s stools. Eggs are then ingested by an intermediate host, in whose tissues the larval stages develop (see plerocercoid; cysticercus; hydatid). Humans are the primary hosts for some tapeworms (see Taenia; Hymenolepis). However, other genera are also medically important (see Diphyllobothrium; Dipylidium; Echinococcus).... tapeworm

Worm

n. any member of several groups of soft-bodied legless animals, including flatworms, nematode worms, earthworms, and leeches, that were formerly thought to be closely related and classified as a single group – Vermes.... worm
