Removed the 'aviation fuels' category - p. aeruginosa can grow in jet fuel but it's misleading to suggest it's a fuel itself. Molly Doonesbury 21:40, 22 December 2006 (UTC)
Mariana Bridi a 20-year-old Brazilian beauty queen - lost her life due to the the contraction of a urinary tract infection caused by the drug resistant bacteria bacteria Pseudomonas aeruginosa. Initially the young model and Miss World finalist was diagnosed with having kidney stones - and was hospitalised in late December 2008 - but she was re-admitted on January 3 in septic shock and life-threatening low blood pressure. Doctors pumped the latest most potent antibiotic drugs into her but could not stem the infection - and were forced to amputate first her feet then her hands - in an attempt to save her life - but tragically on Saturday 24 January 2009 Briidi lost her battle with the infection and died.

In the discussion re:treatment of P. aeruginosa, the article lists piperacillin and ticarcillin as ureidopenicillins that can be used for treatment. While both are in fact antipseudomonal penicillins, ticarcillin is a technically a carboxypenicillin and not a ureidopenicillin, like piperacillin. They could be listed together under the phrase antipseudomonal penicllins or separately under their penicillin classes (carboxypenicllin vs. ureidopenicillin). Doripenem could also be added to the list of carbapenems with activity againsts P. aeruginosa SquidBrandon (talk) 12:00, 27 October 2008 (UTC)
If anyone has access to a suitable picture, but lacks the wikipedia skills to add to the main page, please add it here so a wikipedia-skilled person can put it into the page. Thanks. --Drevicko (talk) 12:03, 1 June 2016 (UTC)
This article has had an incorrect picture for almost 2 years now. —Preceding unsigned comment added by 192.138.76.34 (talk) 21:29, 3 August 2010 (UTC)
Will somebody PLEASE fix the picture? It is not a representative picture of P. aeruginosa, nor is it XLD agar. —Preceding unsigned comment added by 192.138.76.34 (talk) 11:36, 21 May 2009 (UTC)
I've noticed that nobody has fixed this, and its been months since I suggested this correction. I'd do it, but I lack the wikipedia skills to edit the picture in the article, so could somebody get to it?
I don't know how to fix this, but the picture is horribly wrong. It does not resemble P. aeruginosa, which is motile and has a distinct metallic sheen, nor is the media correct (says XLD, looks like BAP).—Preceding unsigned comment added by 68.49.136.206 (talk) 02:53, 10 August 2008 (UTC)
I inserted a section on prevention; I am no expert on pseudomonas and I hope that someone with more knowledge can add more useful information. Although I'm no advocate of probiotics in general, this was the only thing that I could find. The 2004 CDC Guideline for the prevention of ventilator-acquired pneumonia addresses how to clean the equipment to prevent Legionella, but doesn't specifically mention how to disinfect for pseudomonas. Pseudomonas is listed on the Medicare "Never" list, as if it was common knowledge how to prevent this infection; PLEASE insert some relevant information if you have it.....I can't find much.doctorwolfie (talk) 12:39, 25 May 2008 (UTC)
For a topical infection, a doctor recommended keeping the area dry. A note on webmd.com states "These bacteria like moist environments, such as hot tubs and swimming pools, where they can cause a skin rash or swimmer's ear." (3rd paragraph under "Who gets this infection?" (2nd section) ). Drevicko (talk) 05:15, 14 April 2015 (UTC)
Sterilization via Bleach. If it can kill the HIV/AIDS virus, it should kill this. Or colloidal silver? — Preceding unsigned comment added by 76.122.165.13 (talk) 17:35, 12 May 2013 (UTC)
The article says that every antibiotic used against P. aeruginosa must be administered by injection. This is not always the case: my mother had a P. aeruginosa infection under her fingernails, which was cured first by removing her fingernails, then applying antibiotics topically on her nail beds.

I believe there is a possible copyright violation in the paragraph preceding reference 11, as it is talking about our studies, if nothing else it implies OR. If it isn't changed soon, I'll list it as a possible copyright violation. Terri G 10:04, 1 June 2007 (UTC)
what kind of medicine need to the Pseudomonas aeruginosa???
I didn't change anything, but I believe where it says "Definitive clinical identification of P. aeruginosa often includes identifying the production of both pyocyanin and fluorescein as well as its ability to grow at 42°C", that "and fluorescein" should be removed. Fluorescein is common to many types of Pseudomonas, not just aeruginosa. I also found that in Sherris Medical Micro, it says P. aeruginosa is clinically defined as making pyocyanin and growing at 42 degrees (no mention of fluorescein being clinically useful). BruceD270 02:37, 2 October 2007 (UTC)
there appears to be a missing verb in the second sentence of the paragraph on pathogenesis. 'p. aeruginosa uses the virulence factor exotoxin A to (?) adp ribosylate eukaryotic------. To what? produce? inhibit? antagonize? oxidize? methylate? lyse? unfortunately, i'm neither a microbiologist nor a biochemist, so somebody else has to fill in the blank.Toyokuni3 (talk) 14:46, 22 April 2008 (UTC)
got it. i should have realized as soon as i typed 'methylate' that 'ribosylate' was a verb here. domo arigato gozaimasu.Toyokuni3 (talk) 00:48, 25 April 2008 (UTC)
in the resistance section, what is meant by 'p. aeruginosa is a highly relevant opportunistic pathogen'.relevant? just asking.Toyokuni3 (talk) 15:31, 25 May 2008 (UTC)
I added tortilla-like scent right alongside the grape scent. Believe it or not, in Central America this is how P. Aeruginosa is taught - and strangely enough, the smell of fake grape is the same as freshly-cooked tortilla.--Cpt ricard (talk) 05:27, 17 October 2008 (UTC)
This is the problem with wikipedia. I have no idea what this article is about. It reads like a scientific journal which could only be realistically understood by people with doctorates in medicine. Why can't there just be a heading which says "What happens when someone is infected" and then describing what the symptoms and repercussions are? It doesn't mention anywhere in the article that an infection with this bacteria can be fatal. I realise that the information in the article is (most likely) accurate and useful but Jesus Christ why can't we make it useful for a layman? Nambio (talk) 11:33, 22 January 2009 (UTC)
There's a limit to how dumbed-down we can make the article and have it still be useful. 14:37, 16 June 2012 (UTC)Ubiquitousnewt — Preceding unsigned comment added by 65.27.134.141 (talk)
I'm just a nurse and I think this was an easy read. I can suggest that more pictures and more infection control measures be added to this page. Example: What manifestations will I see in the clinical setting e.g discharge, rash, wound appearance? At which point is it airborne, etc? Very useful info here though. Thanks. — Preceding unsigned comment added by 76.122.165.13 (talk) 17:45, 12 May 2013 (UTC)
There are no case histories of treatment discussed in the article. The recent notable case of Mariana Bridi da Costa has been included, and deleted, by various editors. Let's vote here for Keep or Delete:

I notice this article is pretty much all about the medical side of P. aeruginosa, but some strains of the bacteria are used in bioremediation, ie cleaning oil slicks. I will be adding this to this article, but wondered if it should be a separate article. There is a general bioremediation article but this doesn't (atm - I'll be adding to that as well) mention P. Aeruginosa at all.
Thoughts before I embark on this would be welcome. Fork me (talk) 09:15, 23 April 2010 (UTC)
Decent article, and worth keeping, but the text needed cleanup and clarification bad, so I did. 65.27.134.141 (talk) 14:39, 16 June 2012 (UTC)Ubiquitousnewt
Please include a list of additional diagnosis that are commonly mistaken for Pseudomonas Aeruginosa. This would be helpful when trying to do a self diagnosis. — Preceding unsigned comment added by 50.30.217.33 (talk) 19:42, 25 March 2012 (UTC)
P. aeruginosa is very commonly used to study the evolution of social behaviours like cooperation and spite. I would go so far as to call it a model organism - there are quite a few lab groups that are, if not dedicated to P. aeruginosa, at least have a keen interest.
I'll have a go at adding a section about this - I'm sure someone will have written a review paper about P. aeruginosa's use in the study of evolution so I'll dig that out and write it up in wiki style.
I just wondered whether anyone had anything to say about this idea, whether anyone has anything to add?

I've moved the bit about Phage therapy to a separate experimental heading. It is by no means a widely accepted treatment and isn't even approved in most Western countries. The quoted article is a single case report and does not reflect general consensus. --142.76.1.62 (talk) 18:43, 5 September 2014 (UTC)

The author of this section should go back and add sources to the first paragraph under "Antibiotic Resistance and Treatment." Upon research, I found a lot of errors in this section (AdeABC is an efflux pump system in a species of Acinetobacter, not in Pseudomonas aeruginosa), in addition to grammar issues. --Shahrukhkhan1968
Below I quote verbatim sections from an article published on 18 May 2016 on the cystic fibrosis website cfroundtable.com:
The potential drug therapy relies on an engineered cationic antimicrobial peptide, or “eCAP,” which is a synthetic and more efficient version of naturally occurring antimicrobial peptides that form a first line of defense against infections in humans. Developed by co-author Ronald C. Montelaro, Ph.D., professor and co-director of Pitt’s CVR, the eCAP works by “punching into” bacteria and viruses, thereby destroying them.
Dr. Bomberger and her team tested the eCAP in the laboratory by growing biofilms of drug-resistant Pseudomonas aeruginosa bacteria on the cells that line the airway and then treating them for one hour with the eCAP. The eCAP was 50 times more effective at fighting the biofilm than traditional treatment, but did not harm the airway cells. — Preceding unsigned comment added by Obsidionite (talk • contribs) 14:21, 21 May 2016 (UTC)

This seems relevant but it would be better if an informed person decides.

My doctor suggested keeping the area dry as a good treatment of skin infections, and I've found it to be effective - at least it reduces symptoms to the point that is seems to go away. Spending a day in the pool however causes a relapse ):
Anyway, if anyone knows of research into keeping dry and/or salt baths for skin infections, please add it to the page.

I think a section on the discovery and implications of P. aeruginosa throughout history would be good information to add. This article mostly focuses on research and clinical aspects of the bacterium. Thoughts? Ssp5762 (talk) 01:30, 23 January 2017 (UTC)
I'd like to add some information on the history, epidemiology, and transmission of this bacterium. Some information I'm thinking about adding is who discovered P. aeruginosa and how, some facts on epidemiology, and how P. aeruginosa is transmitted and cause infection. I found some sources that I listed below. Can you tell me what you think about the sources? Thanks!

I recently wrote an article on twitching (here) and I thought it would be useful to write a short section on its roles in this organism.

Despite the name, P. aeruginosa pyoverdine (or rather, pyoverdineS) without the presence of pyocyanin are yellow. A very distinct, fluorescent yellow. I know this for certain as I culture pyocyanin-negative, pyoverdine positive P. aeruginosa frequently (NCTC 10332 is a good example) and it stains the agar and broth an unmistakeable yellow (with a distinct blue fluorescence under UV). Yet bizarrely, literature on pyoverdines - on which there are many - do not seem to note colour. Just throwing this in there... though I would also appreciate any advice on how to overcome this minor colour issue. Would a citation of absorbance maxima be acceptable or is this too technical? 146.191.95.1 (talk) 12:20, 10 March 2022 (UTC)

Reorganized the previous table under Identification and changed the subheading to "Classification". All the previous information was moved to the new table and a few more tests were added to the table. Also, a few sentences were added to the discussion of trouble with identification of the species mentioning the variations that can be found in colony morphology.
