Talk:Ernest Duchesne

message: There were fifteen years between his doctoral defense and his death. Was he in the army the whole time? What was he up to? Rmhermen 06:08, Apr 3, 2004 (UTC)
:I've just found a rather detailed chronology of his life at http://www.bium.univ-paris5.fr/sfhad/vol8/article09.htm

:* 1897, he defends his thesis at age 23.
:* 1898, one year internship at Val de Grace.
:* 1899, he is appointed "Médecin Major de 2eme classe au 2 nd Regiment de Hussards de Senlis".
:* 1901, he marries Rosa LASSALAS, from Cannes. She dies 2 years later of tuberculosis.

thread_title:  Better references

message: It must have been a different strain of peniccilin than that which Fleming found, since Flemings version did not cure Typhoid, but this one did.DanielDemaret 06:45, 31 March 2006 (UTC)
thread_title: Typhoid

message: Today, the strain discovered by, Notatum Fleming is the one that produces antibacterial medicin as far as I can see. I can see other uses for Glaucum, but I have not yet found it for antibacterial purpuses. Any help?DanielDemaret 07:53, 31 March 2006 (UTC)

While Fleming generally receives credit for discovering penicillin, in fact technically Fleming rediscovered the substance.  In 1896, the French medical student Ernest Duchesne originally discovered the antibiotic properties of  Penicillium, but failed to report a connection between the fungus and a substance that had antibacterial properties, and Penicillium was forgotten in the scientific community until Fleming’s rediscovery.

message: It can be really distracting when trying to look for references on this and related subjects, only to find that many web pages use wikipedia as a reference. Hard to look for veracity when this encyclopedia becomes the original source. It is kind of a closed loop then. DanielDemaret 08:25, 31 March 2006 (UTC)

Intrigued, Duchesne prepared a solution of the mould and injected it into a so showed that an animal inoculated with a normally lethal dose of typhoid bacilli would be free of the disease if the animal was also inoculated with Penicillium glaucum.  — Preceding unsigned comment added by 24.19.248.239 (talk) 08:32, 21 November 2012 (UTC)
thread_title:  Missing text 

message: Okay, I spent a short blip trying to make this article suck a little bit less.  To be clear, there's a bunch of uncited, potentially incorrect material in place, including missing text from 2012.  The arab saddle boy thing, to be clear, may be true -- I found it mentioned in a random book, but I'm concerned that book may have looked at this wikipedia article for it's source.  If there is someone that speaks french and english, this is a PERFECT opportunity to look at the french version of this article and translate that for the english page -- it's in much better condition over at fr.wikipedia.org.  Hopefully this message won't get lost in the mix, somebody who knows this stuff needs to do a thorough review of this article.  --Pg8p (talk) 11:39, 10 August 2014 (UTC)
thread_title:  This Article Sucks 

message: At present, this article reads as follows:
In Duchesne's landmark thesis, Duchesne begins testing the effect of tap water on mold finding mold is significantly diminished when exposed to French tap water.  After detailing 19 different experiments, Duchesne concludes the presence of Penicillium glaucum inhibits bacterial growth: 
It is apparent that whoever added this passage can't read French because it states precisely the opposite of what the editor claimed that it states.  The translation is as follows:
All these experiments lead to the same results:  the presence of bacteria in the medium where one cultures molds is, for the latter, a cause of [their] rapid destruction, even if the molds had had time to become accustomed to the nutritive medium before the introduction of the microbes.
In other words, the bacteria kill the molds, not vice-versa.  (The original passage appears here:  (Duchesne, 1897), p. 36.)  So I will delete this passage.  
However, the other quoted passage is more relevant.  I will provide a translation of it.

thread_title:  Error 

message: Duschesne's filtrates were observed to kill gram negative bacteria, however penicillin has little or no effect on gram negatives, due to the lack of a cell wall. Penicillin is only effective against gram positive bacteria as its mode of action is to lyse the bacterial cell wall. This causes cytolysis and therefore cell death.

I'm sure there are more legitimate sources to be found. I've could've have written this just from basic molecular biology knowledge, but I was prompted to do so by this article.  — Preceding unsigned comment added by 143.167.226.88 (talk) 17:20, 25 May 2016 (UTC)
