The link for reference 5 is not working, but I found the same basic info in another article which you might want to add a reference to: It is dated Feb. 28, 2008. This is my first Wiki post and so I am reluctant to modify the article myself.Jfodsire (talk) 12:27, 8 January 2010 (UTC)


I think it would be very helpful to have a less technical section describing this topic for the lay person. This article is not helpful at all to the person wanting a general overview of this topic. My high school students would not find this entry useful at all! SciencePerson (talk) 14:28, 6 August 2008 (UTC)


Generally speaking I think adding a new 'Prevention' section would seem to be appropriate for these types of articles? I have unsuccessfuly looked online to find something on disinfection and prevention methods against this bacteria.AlexGWU (talk) 17:33, 16 February 2008 (UTC)


The picture shows colonies of Pseudomonas growing on a solid growth media which contains blood. Its not fresh liquid blood, but more like a blood jelly (the jelly is a substance called agar)

Is Pyocyanin also a fluorescent substance?

Yes, its one of the commonly-encountered siderophores which are secreted by the Pseudomonads to scavenge iron. Although its name suggests its a light blue color, the reality is that pyocyanin fluoresces a green colour.

Antibiotic contradiction.[edit]

The article states there is a resistance to beta-lactam antibiotics, then lists sensitivity to imipenem. Imipenem is in the Carbapenem class - which is a beta-lactam antibiotic.

A Few Questions[edit]

  1. I think the list of bacteria formerly classified as Pseudomonads is useful, but the list is getting long. Should a separate page be set up to list the discontinued names? This would serve as a valuable resource to locate the modern designations for old names without cluttering up this page.
  2. Would there be any value in including type collection numbers (e.g. ATCC)?
    • I went ahead and put in the type strain numbers.

Taxonomy section[edit]

The text in the taxonomy section of this article seems to be identical to an internet blog entry here:

It cites as a reference a book which isn't going to be published until next year. I don't know if this perhaps constitutes a conflict of interests, but thought I should flag it up. Any thoughts? Pseudomonad 14:41, 12 October 2007 (UTC)

Hi, the book is the correct reference/citation and although it has a 2008 date copies are in the bookshops already (I have a copy). The material on the taxonomy section is taken from the book (with the permission of the copyright owner) Touchstone42 09:29, 13 October 2007 (UTC)

Ok, I don't think that using this block of text verbatim has integrated well into the existing article though. It touches on issues already addressed in the 'species previously classified as Pseudomonas' section, so maybe some rewriting to combine the two into one section might be in order, I may give this a go if I have time later.

minor addition[edit]

added mechanical ventillation in addition to CF as group of patients most susceptible to pseudomonas respiratory infections. (talk) 04:51, 24 February 2008 (UTC)

British or American?[edit]

I noticed there are a lot of ", and" and "ize", which is odd as most other microbiology pages are in British English. Can I switch the article over to the Queen's? --Squidonius (talk) 21:23, 11 July 2011 (UTC)


References are missing for the information describing the unusual places that these bacteria have been found (antiseptics, etc). (talk) 22:35, 31 December 2014 (UTC)

Species previously classified in the genus[edit]

δ proteobacteria: P. formicans is linked to Aeromonas cavia, but this belongs to γ proteobacteria. ==>There is an error. Who can corrct? Ernsts (talk) 19:20, 28 September 2016 (UTC)

Green urine[edit]

According to a YouTube video, a pseudomonas infection can sometimes produce green urine. This was added by someone not logged in and was deleted by someone else, presumably not credible. If someone knows a more credible source, it could make a useful addition to this article. DavidMCEddy (talk) 04:49, 13 June 2017 (UTC)

That is not a reliable source per WP:MEDRS. Jytdog (talk) 05:53, 13 June 2017 (UTC)

Food spoilage other than milk?[edit]

@Lincolnp8: I wish to than User:Lincolnp8 for expanding the section on "Food spoilage agents" as requested.

However, I have questions about what was done:

First, citations were deleted regarding the following:

Shouldn't these still be mentioned? Or am I just getting in a hurry, and Lincolnp8 is in the process of making such changes?

If those mentions were deleted for a reason, I hope someone will mention here why they were deleted.

Second, what's PCR? Polymerase chain reaction? I assume this must be it. However, I know very little about this field other that a few books and articles I read that supported changes I made to the article on phage therapy in 2015 and 2016. I will change the first mention of PCR so it says "polymerase chain reaction (PCR)" and links to the article on it. If that is NOT correct, I trust someone will correct this change.

Thanks again, DavidMCEddy (talk) 13:33, 20 November 2017 (UTC)
