Talk:Parasitic worm

Section on Prevention is not clear

I think the section on preventation is also really important. There are 2 paragraphs in there which are on deworming which I would not really call "prevention" but this is rather part of "curing" someone? Deworming programs are important but I am not sure if it fits best under "Prevention". The Fit for Schools Program in the Philippines would be a great one to cite for deworming programs in developing countries. EvM-Susana (talk) 12:18, 21 October 2014 (UTC)

Explaining about the disease naming convention (-sis) to lay people

I have added this sentence now to make it clearer for lay people. It was even new for me...: The same naming convention applies to all helminths whereby the "-sis" at the end of the name of the worm is added to signify the infection with that particular worm, e.g. Ascaris is the name of a particular helminth, and Ascariasis is the name of the infectious disease caused by this helminth.

Good? We could add the same or similar sentence also to the page on helminthiasis. EvM-Susana (talk) 08:49, 24 October 2014 (UTC)

Need a bit more information about the egg / ova thing

Helminth eggs is what we measure in sanitation, so I think we need some more information about the fact that these worms hatch out of eggs. This I think is not covered sufficiently in this article. Perhaps we could take some sentences about the egg thing from the article on Ascaris which seems rather detailed. As far as I know, all helminths hatch from eggs. EvM-Susana (talk) 08:51, 24 October 2014 (UTC)

Not quite that easy I suspect. Since "Helminth" is a polyphyletic grouping, there is no consistency about reproduction or eggs. Some of the Trematoda such as Gyrodactylus release living larvae and there would no eggs to count. Although Gyrodactlus is not of concern in human parasitology (unless we have editors who are fish) , I think it would be incorrect to make assumptions about eggs except perhaps to say that some helminths release eggs which can be counted in sewage.  Velella  ^{Velella Talk}   20:38, 25 October 2014 (UTC)

Ah, I didn't know that. In sanitation we often speak of "helminth eggs" and then specifically of "Ascaris eggs" (because they are the easiest to count under a microscope??). Could someone add the right sentence then, e.g. "Most of the common helminths that are causing helminth infections inflicting humans reproduce via an egg phase. These helminth eggs are also called ova and can be detected in the faeces of an infected person as well as in the faecal sludge from pit latrines. One example for a helminth that is reproducing via eggs is Ascaris". Can someone verify if tis is correctly worded like this? EvM-Susana (talk) 21:27, 25 October 2014 (UTC)

Ascarid worms do indeed produce easily identifiable and countable eggs. Tape-worms however produce flat body-segment like eggs, and many flukes produce eggs that never escape the human body as they grow into various juvenile stages and can migrate into other body organs. It might therefore be simpler to say something like "Round worms produce numerous eggs that are easy to count under the microscope and can give an indication of the extent of parasite infection in the local population" or some such similar text. As I noted above, making all-encompassing statements about polyphyletic groups is always a challenge, and best avoided.  Velella  ^{Velella Talk}   21:39, 25 October 2014 (UTC)

Enumerating helminth eggs

I am planning to add information about enumerating helminth eggs and am wondering if such information fits better on the page on helminths or on the page on helminthiasis (or both)? It is not about the number of people infected but rather how to determine the number of helminth eggs in a sample of faeces of faecal sludge. We are doing this a lot in sanitation to determine if a sludge treatment process has led to a reduction in helminth eggs. But if it is used on a sample of fresh faeces, then it could also become part of the diagnosis step and therefore belong on the helminthiasis page. EvM-Susana (talk) 09:34, 3 November 2014 (UTC)

Most of the complications in standard protocols for looking for Ascaris eggs in samples from various sanitation systems are due to finding one egg in a large amount of water or soil, — Preceding unsigned comment added by 62.235.179.170 (talk) 11:38, 18 January 2016 (UTC)

viviparous

fe,

   Genus Gyrodactylus, which has no eyespots and is viviparous.(othrex-c,highrup)

so Characteristics that are common for all helminths include:

Life time:

• The life time of adult worms varies tremendously from one species to another but is generally in the range of 1 to 8 years (see following table). This life time of several years is a result of their ability to manipulate the immune response of their hosts by secreting immunomodulatory products.
• Helminths can be either hermaphrodites (i.e. can have both sexes), like tapeworms and the flukes (except the blood fluke which is not a hermaphrodite), or have their sexes differentiated, like the roundworms.

Eggs:

• All helminths produce eggs (also called ova) for reproduction. NEDZA REWRITE,, — Preceding unsigned comment added by 62.235.179.170 (talk) 13:14, 18 January 2016 (UTC)

Requested move 8 September 2018

The following discussion is an archived discussion of a requested move. Please do not modify it. Subsequent comments should be made in a new section on the talk page. No further edits should be made to this section.

Moved back to parasitic worm; there is a consensus for this outcome, after extended discussion. bd2412 T 01:36, 17 October 2018 (UTC)

Helminths → Helminth – Plural to singular, in order to match naming conventions delineated at NCPLURAL.  — Mr. Guye (talk) (contribs)  02:33, 8 September 2018 (UTC) --Relisting.

• Support as per reasoning. --Iztwoz (talk) 06:59, 16 September 2018 (UTC)

• Move to Parasitic worm per WP:COMMONNAME. Rreagan007 (talk) 06:08, 8 September 2018 (UTC)

Parasitic worm is not the common name according to google hits and ngrams.--Iztwoz (talk) 07:06, 16 September 2018 (UTC)

• Support move to singular name. Oppose move to Parasitic worm as this is a non-specific term capable of referencing a wide range of parasitic organisms from Guinea worm, round worms (Ascaris) , Flukes , Plasmodium etc. not all of which fit into the rather wide definition of Helminth adopted here. I would have preffered that this article had adopted the much narrow medical definition of Helminth restricting it to the Platyhelminths (hence the name).  Velella  ^{Velella Talk}   09:31, 16 September 2018 (UTC)

• If so, then parasitic worm should be a disambig page rather than redirecting here. Rreagan007 (talk) 21:30, 16 September 2018 (UTC)

In answer to Vellela - the name Helminth means worm; platyhelminths are flat worms (platy - flat) so the usage of the name is fine. In answer to Rreagan

helminths are worms that are parasites and parasitic worm is an aka of helminith; helminthiasis is any of the diseases caused.--Iztwoz (talk) 06:47, 17 September 2018 (UTC) Parasitic worm now redirects to the disambiguation page.--Iztwoz (talk) 17:25, 17 September 2018 (UTC)

Is it beneficial to change the title to singular, even if helminths never really occur in singular, i.e. they are usually always in packs of hundreds or more. Just wondering if for that reason helminths (plural) is not the better title? A Google search gives slightly more search results for the plural form (if that has any relevance here). Just wondering. EMsmile (talk) 14:25, 17 September 2018 (UTC)

• Comment: Note that NCPLURAL has two highlighted exceptions, not just the one about cases where the title only exists in the plural. It says that the plural form may be used for "Articles on groups or classes of specific things". Here it seems that there is no specific taxon for "helminth". As the article says, "There is in fact no helminth classification; it is an 'artificial' term." In that sense, "helminths" may resemble "Flight control surfaces", since there is a diversity of different things that are called helminths. I once proposed renaming that article to the singular form and received an education in the concept of "classes of objects". —BarrelProof (talk) 19:48, 17 September 2018 (UTC)
• Move back to parasitic worm per WP:COMMONNAME and RReagan. Note that this was the name of the article until 2013, when it was cut-and-paste moved without discussion from parasitic worm to helminths. (I have just done a WP:HISTMERGE to reunify the attribution history of the two articles).  — Amakuru (talk) 20:50, 23 September 2018 (UTC)
• Move back to parasitic worm per WP:COMMONNAME. Guinea worms are parasitic worms? They are of the nematode type. Plasmodium are not worms but a eukaryote (worms are multicellular). Platyhelminths has an article and it is called flatworm Doc James (talk · contribs · email) 15:56, 15 October 2018 (UTC)
• Move back to parasitic worm. Helminth shows more on ngram but not on regular search. Looking again without use of commas (that somebody advised using - long ago) shows a far greater usage of parasitic worm.--Iztwoz (talk) 18:02, 15 October 2018 (UTC)
• This is getting confusing. If people want to move it to parasitic worm can you please open a new move request discussion for it? This move discussion was for helminths to helminth. I am for using helminth because from where I come from (sanitation sector), helminth, together with helminthiasis is the more commonly used term. Helminth eggs is an important indicator for the quality of fecal sludge after treatment. Can we have a disambiguation page for parastic worm, rather, like it was suggested by Rreagan007? Also, I thought helminth equals intestinal worm rather than parasitic worm. But I keep getting confused about that one, I guess some helminths also live in other places, not just the intestines.

Wrongly moved page

The proposed move was from Helminths to Helminth. There was no discussion as such on a move from Helminths to Parasitic worm. Why has this been hijacked. What was wrong with listing it for discussion first? As pointed out on the moving editor's page as it is the page is a mess due to use of helminth throughout. Is the eager moving editor going to fix this? Also as argued by editor that there was consensus on this - not true only supported twice by RReagan.--Iztwoz (talk) 12:32, 25 September 2018 (UTC)

The one suggestion that it be moved to Parasitic worm was also supported by Amakuru one day before the page was moved. This does not constitute a discussion. I have asked the closer to re-open the page move proposal and for any interested editor to open a move proposal from helminth to parasitic worm.--Iztwoz (talk) 08:41, 26 September 2018 (UTC)

Any search including ngrams will show clearly that the common name is Helminth.--Iztwoz (talk) 08:49, 26 September 2018 (UTC)

so it seems it's been changed back to how it was: Helminths. Good. EMsmile (talk) 14:04, 12 October 2018 (UTC)

Nowt it's been moved again by User:BD2412! Why the mad rush? I don't feel like consensus has been achieved after only a couple of people voiced their opinions. I really don't think why this needed to be rushed and not further opinions collected first! EMsmile (talk) 04:24, 17 October 2018 (UTC)

EMsmile I agree. Let us have it back at Helminths and have a proper discussion 08:31, 17 October 2018 (UTC) — Preceding unsigned comment added by Velella (talk • contribs)

The discussion had been going since the beginning of September. It was already moved to "parisitic worm" and then reversed once, now the consensus from the discussion above is even clearer and the issue has been put to bed by an independent admin.

Unclear on multiplication or reproduction in humans

I have difficulty with the sentence in the lead "In their adult forms, parasitic worms cannot multiply in humans." The most obvious (mis?)interpretation of this is that the worms cannot reproduce in humans, but that seems to be incorrect. It it the case that no helminth can increase its adult population in humans (but can reproduce and release eggs)? If so, then I suggest this is explained more clearly.
