Talk:Listeria

General question

Does it kill listeria to cook the pizza ?

According to the page on listeriosis, yes.

- Text in Listeria Page section "Epidemiology" links to the "Nutrition Action Healthletter," which has different text than what is included in the "Epidemiology" section. Notably the "epidemiology" section adds cantaloupe and the green lipped clam info. I know cantaloupe have been reported, but it is not from the source footnoted here. Could someone please update the quote to be accurate and maybe find another source for some of the other vectors mentioned?

• *New* Animals can be carriers. Does that include humans also?

Suggestion

Since it's a disease, could anyone who knows more about it add typical symptoms and other information on that to this page? I, however, know nothing, so I apologize for not doing so myself. >_> 67.83.72.38 22:58, 2 March 2007 (UTC)

There are six species of Listeria: moncytogenes, innocua, welshimeri, seegelieri, ivanovii, and murrayi (syn. L. grayi). An seventh species, Listeria denitrificans was reclassified Jonesia denitrificans in 1987.

Also the text about mouse infection is a bit misleading. As far as I am aware innocua and murrayi (syn. L. grayi) are considered non-pathogenic. L. welshimeri, seegelieri, and ivanovii rarely cause human infcetion.

L. seeligeri

Only people named Larry get this disease. I have always known it as Listeria seeligeri, but upon a cursory look around the web I have found both spellings mentioned. Not sure if it's a regional thing or what, anyone else know?ClamsonJ 20:49, 15 August 2007 (UTC)ClamsonJ

According to the List of Prokaryotic names with Standing in Nomenclature, Listeria seeligeri is the correct form. I've changed the Listeria page to reflect the corrected spelling. -- MarcoTolo 20:55, 15 August 2007 (UTC)

Cell invasion

Are you absolutly sure about this?: "Listeria induces macrophage phagocytic uptake by displaying D-galactose receptors that are then bound by the macrophage's polysaccharide receptors (Notably, in most bacterial infections it is the host cell, not the bacteria, that displays the polysaccharide)."

From what I am aware, Listeria monocytogenes binds to E-cadherin of intestinal epithelial cells inducing phagocytosis. —Preceding unsigned comment added by Diuness (talk • contribs) 02:22, 21 October 2007 (UTC)

Initial infection

Are humans infected by spores, or by live organisms? How does it survive passage through the digestive tract? How many spores or cells must normally be ingested at once for infection to occur? Are certain HLA types more susceptible than others? Apparently, most people exposed or infected never become ill. What accounts for the small number who do? Is it just chance? Inquiring minds want to know. 69.108.167.22 (talk) 02:35, 28 September 2011 (UTC)

Written for Scientists Only, Overrated

Looked this article up after reading in NYT about a listeria outbreak fr/ organic produce. This article tells me nothing about the vectors of infection, in other words, HOW ARE PEOPLE INFECTED, do they ingest it, breath it, drink it, through a skin break? The article also isn't written for laypeople to understand it. The 'clarity of writing' rating is way to high. Can someone please remedy this? Tapered (talk) 03:52, 28 September 2011 (UTC)

==The article should include a list of symptoms. That is what the non-scientists is looking for.

Good feedback. I did add a signs and symptoms section. Gandydancer (talk) 12:46, 29 September 2011 (UTC)

OK, I see the problem here. It seems that Listeria comes in 6 varieties and it is the Listeria monocytogenes that leads to the disease. Rather than cover this variety so thoroughly in this article it should direct to the Listeria monocytogenes article and that one should direct to the disease article - which is where we should be putting this information on this current outbreak. If someone that works on bacteria articles would do this, it would be great. If nobody else takes care of it, I will see what I can do even though it is a little out of my range of knowledge. Gandydancer (talk) 15:41, 29 September 2011 (UTC)

I have updated the listeriosis article. Gandydancer (talk) 17:02, 29 September 2011 (UTC)

It's still too technical, yet omits essential information. We know thaf e. coli comes from colons, i.e. from manure, but there is no mention of what the main source of listeria is, therefore no help in preventing its spread. — Preceding unsigned comment added by 184.147.135.3 (talk) 23:35, 10 April 2015 (UTC)

I AGREE

This article reads like the algebraical formula Einsteins theory for calculating the amount of light escaping from a collapsing star. Simply tell the layman what causes it, where it comes from, etc. without all the science slang and jargon. I read the entire article and still don't have a got damned clue what Listeria is, does, comes from, or is controlled with. You don't have to impress me. I didn't come here to get impressed by your technical jive. Simply explain it in "regular-old" English!

EX:

• " facultatively anaerobic, non-spore forming bacilli." WTF is that?

• "Gram-positive, nonsporeforming, catalase-positive rods" and that means?

• "monocytogenes is a distinct taxon within the Lactobacillus-Bacillus branch of the bacterial phylogeny" HUH?

• "It induces directed polymerization of actin by the ActA transmembrane protein" Nice. Now what is that?

I shouldn't have to have a PHD in microbiology to understand your article.

Problems with article

I am trying to do some work on the article, since the media keeps saying that "Listeria" has caused infections, when they really mean Listeria monocytogenes (come on, that just rolls off the tongue!). This article is about the Listeria genus, which contains at least 7 species. Only one (barely two) actually cause disease in humans. Hopefully I can reorganize the article to better reflect this, and hopefully redirect casual readers to the relevent articles at Listeriosis and Listeria monocytogenes.

Hi there! I should have started a new section - see my above edit. I have added some info to the listeriosis article which I believe would be the appropriate one. Thoughts? Gandydancer (talk) 17:58, 29 September 2011 (UTC)

Thanks. I noticed your last comment after I started this section, so it was a little redundant. Still, I feel it would be best for the article to shorten the signs/symptoms section and created a Main article - Listeriosis at the top of the section. Angryapathy (talk) 20:32, 29 September 2011 (UTC)

Listeria can also be like yo wats up and kill people in like a instant yo — Preceding unsigned comment added by 24.90.31.134 (talk) 18:09, 30 September 2011 (UTC)

A quick look at the article will turn readers away -- this comes up #1 in google and there is no mention of SYMPTOMS and TREATMENT in the any of the headings. The public is being sent here by google and they will only learn that wikipedia is not the place for them. Regardless of the hairs being split over the exact terminology, why not at least redirect the public to the right page WHEN PEOPLE ARE DYING AND THE DISEASE IS SPREADING (Now on lettuce in California). This isn't rocket science. 152.132.10.133 (talk) 21:22, 30 September 2011 (UTC)

You can start by getting rid of the tag at the top of the page -- it clutters that whole top so no one will notice the single line on the entire page that differentiates this page from the "disease" of the same approximate name. 152.132.10.133 (talk) 21:23, 30 September 2011 (UTC)

What are its Vectors?

What are the avenues for this disease's transmission? That it is caused by a bacterium is explained exhaustively but how does it make it into the human food chain? via traces of human and animal feces? — Preceding unsigned comment added by 99.198.30.48 (talk) 13:25, 11 May 2016 (UTC)

Greenyard, 9 dead

I read that Greenyard has spread this, causing 9 deaths. Greenyard did not publish themselves btw. EFSA reacted late. -DePiep (talk)

Symptoms ?

Should there not be a section covering the symptoms — Preceding unsigned comment added by 82.43.102.143 (talk) 07:16, 26 November 2018 (UTC)

I don't care so much what happens on a cellular level as much as I care about quickly identifying the initial symptoms and how the disease progresses. Like will it kill me, give me diarrhea, or make me brain dead. As it is the article is generally too technical, as if to be impressive, but misses the point of understanding the organizm's disease. — Preceding unsigned comment added by 2601:246:0:5F90:8B2:153C:4827:73D9 (talk) 01:29, 19 April 2019 (UTC)
