Talk:Trematode life cycle stages

I think the former situation, in which there were separate (albeit poorly developed) pages for each of the developmental stages, was preferable to lumping them all in a "miracidum" page.


 * A generalized name would be better too. —Preceding unsigned comment added by 99.229.128.125 (talk) 22:37, 19 October 2007 (UTC)
 * Moved from Miracidium to Trematode lifecycle stages. Anxietycello (talk) 22:24, 20 November 2010 (UTC)

Problem with this article and its current title
This article is generalizing about lifecycles in the large and very diverse class Trematoda based primarily on the subclass Digenea. I think it would be better to have a vocabulary list explaining the names given to trematode larval forms, followed by several sections each one giving an actual lifecycle of a particular species. Given the article title, it should also include a lifecycle from the subclass Aspidogastrea. Sharktopus talk  16:09, 19 February 2011 (UTC)

I think you could add more information to the egg stage such as could be found in feces, sputum or urine. It could either be embryonate, which means it's ready to hatch or it could be unembryonated which means it's still immature. All of them are opercolated besides schistosomes,as well as mentioning that some eggs are eaten by snails while others hatch in their environment. — Preceding unsigned comment added by Jcichocki (talk • contribs) 22:24, 23 March 2018 (UTC)

Peer Review
Hello, Your article seems to be coming together well. My only suggestion would be to watch your grammar in certain areas of your article:

Trematodes or flukes are small parasitic flatworms that use vertebrates as their definitive host and mollusks (usually freshwater snails or land snails) as their intermediate host.Their life cycle has several varied stages. The life cycle of a typical digenean trematode begins when its egg is immersed in water. Following this, the miracidium (explain what miracidium is) hatches, which swims to find a mollusk host. The miracidia goes through several stages in the mollusk, eventually emerging as motile cercariae larvae.[1] The cercariae either infects vertebrates through the skin or is ingested. In its vertebrate host, the cercaria matures to an adult form (fluke), and lays eggs that are discharged with the host feces or urine. In the presence of open water, the eggs hatch and the miracidium stage of life is reached again.

Egg Discharged either in open water or in intestine of definitive host. Miracidium (plural miracidia) A free-living motile form, covered with cilia, and settles in the mollusk to become a sporocyst.[3] Sporocyst An elongated sac, produces either rediae or more sporocysts.[4] Redia (plural rediae) A larval form with an oral sucker, produces either more rediae, or cercariae.[4] Cercaria (plural cercariae) The larval form of the parasite, develops within the germinal cells of the sporocyst or redia.[4] A cercaria has a tapering head with large penetration glands.[3] It may or may not have a long swimming "tail", depending on the species.[4] The motile cercaria finds and settles in a host where it will become either an adult, or a mesocercaria, or a metacercaria, according to species. Mesocercaria A cercaria little modified but resting. Metacercaria A cercaria encysted and resting. Cercaria is also used as a genus of trematodes, when adult forms are not known.[5] The usage dates back to Müller, in 1773.[6]

Adult The fully developed mature stage and is capable of sexual reproduction.

Other than those changes, the article is fine! — Preceding unsigned comment added by Ooluw003 (talk • contribs) 20:53, 2 April 2018 (UTC)


 * Actually, no, the article is still very poorly written. As an encyclopedia entry, it is actually appalling.  I'd start working to fix it, but I'd end up rewriting the whole thing (yes, it's that bad).   Honestly, I don't even know where to begin.  A loose noose (talk) 04:01, 22 January 2019 (UTC)
