Eucestoda, commonly referred to as tapeworms, is the larger of the two subclasses of flatworms in the class Cestoda (the other subclass being Cestodaria). Larvae have six posterior hooks on the scolex (head), in contrast to the ten-hooked Cestodaria .
Some six thousand species have been described; probably all vertebrates can host at least one species. The adult tapeworm has a scolex (head), a short neck, and a strobila (segmented body) formed of proglottids. Tapeworms anchor themselves to the inside of the intestine of their host using their scolex, which typically has hooks, suckers, or ...
The tapeworm affects the behavior, life history, and morphology of the T. nylanderi ant, as well as indirectly affects its uninfected nest-mates. [3] The ant larva is infected after feeding on bird faeces contaminated with A. brevis eggs. The tapeworm penetrates the ant's gut wall and develops into a cysticercoid within the haemocoel. [2]
Tapeworms are parasites that live in the bodies of their hosts including humans. A 38-year-old man from China was one such host -- recently having a 20-foot-long version of the parasite removed ...
Using a tool with a camera, the doctors discovered a sac of larvae from a tapeworm inside the brain. CBS SF says the live parasite had formed a cyst, which had blocked off circulation inside of ...
Thelazia is a genus of nematode worms which parasitize the eyes and associated tissues of various bird and mammal hosts, including humans. [2] [3] They are often called "eyeworms", and infestation with Thelazia species is referred to as "thelaziasis" (occasionally spelled "thelaziosis").
An 18-year-old who was suffering from a severe tapeworm infection died not long after being diagnosed with the condition. Teenager dies of tapeworm egg infestation in his brain Skip to main content
D. latum is the longest tapeworm in humans, averaging ten meters long. Unlike many other tapeworms, Diphyllobothrium eggs are typically unembryonated when passed in human feces. [4] In adults, proglottids are wider than they are long (hence the name broad tapeworm). As in all pseudophyllid cestodes, the genital pores open midventrally. [5]
