Who wrote "S. pneumoniae is the most common cause of bacterial meningitis in adults" in the introduction to the article? This statistic is only true in the USA. In the meningitis belt of Africa, the most common cause in adults is meningococcus group A, in other parts of the world it can be Streptococcus suis, in other parts of the world it is typhoid. I move to modify this statement to read: "S. pneumoniae is one of the most common cause of bacterial meningitis in adults, and is the leading cause of bacterial meningitis in adults the USA." --Gak 11:17, 28 December 2006 (UTC)

Hi Gak: I'm surprised I didn't catch that. I definitely agree with your motion. MetsFan76 15:12, 28 December 2006 (UTC)

I had the same thought when reading that sentance, is there any reason you didn't change it, erm, 5 years ago? I will change it now as Neisseria is certainly the most common cause worldwide, and indeed in most western countries nowadays. Philman132 (talk) 09:14, 10 August 2011 (UTC)

The most common cause of bacterial meningitis in Australia is neisseria meningitidis, for people's interest. —Preceding unsigned comment added by (talk) 11:14, 11 September 2008 (UTC)

I cleaned up the antibiotics discussion a little. Dyslexic3 03:45, 9 February 2007 (UTC)


I think that as well as the electron microscope photo, there should be a light microscopy and Gram stain photo of S. pneumoniae, as this is what is actually seen clinically (talk) 11:17, 11 September 2008 (UTC) Shane

It is a really bad bacteria to be in your body. Be careful. Wash your hands everyday. —Preceding unsigned comment added by (talk) 14:58, 30 January 2009 (UTC)

Different from the bacteria that causes strep throat[edit]

I researched and found that this Streptococcus that rats can catch from humans (see pet rat section) is NOT the same one that we contract strep throat from. That is hightly significant and there is no mention of it. (talk) 02:00, 2 August 2009 (UTC)

Changed "virus" to "bacteria". Streptococcus bacteria are the cause of strep throat. The significance of whether the Streptococcus pet rats can "catch" from humans is the same or different from the Streptococcus that causes strep throat is open for discussion. (talk) 09:23, 14 May 2013 (UTC)

Overuse of technical terms[edit]

This article has a Flesch Reading Ease of 26.78 which indicates that the article can only be fully understood by University graduates. This means that the article needs to be simplified for those readers who cannot understand the technical terms that you and I can. (talk) 23:21, 18 September 2009 (UTC)

Aerobes vs Facultative anaerobes[edit]

Seems like there's a mistake in the first paragraph. Streptococcus pneumoniae is technically a facultative anaerobe not a pure aerobic bacteria (according to all the sources I've read, except this page). Here is a source from — Preceding unsigned comment added by (talk) 14:13, 23 October 2014 (UTC)

Not really a mistake. An organism can be both aerobic and facultatively anaerobic. And there are streptococcus strains that are strict or obligate aerobes. But since we see this through a prism of thinking important those strains that cause human disease, it's probably best to make the change you suggest, as most of those are facultative anaerobes. This shouldn't cause any misunderstanding as we already state that it's aerotolerant. - Nunh-huh 18:46, 23 October 2014 (UTC)
I understand that there are streptococcus strains that are classified as aerobes, but streptococcus pneumoniae is normally classified as a facultative anaerobe. However, you are right about "aerobe" and "facultative anaerobe" not being mutually exclusive. Another thing I want to mention is that one of the reasons I was originally confused by this sentence was because of the use of the word aerotolerant. Normally it's used to describe anaerobes that can live in the presence of oxygen (i.e. tolerate it). Therefore, technically, there's no such thing as an "aerotolerant aerobe", since aerotolerant bacteria are by definition not capable of using oxygen. I know I may be a little too picky about the vocabulary used, but I think the word "aerotolerant" should be deleted.
I'm going to go with your suggestion, as it makes sense to me that (as you say) "aerotolerant" is at best redundant and at worst confusing. If anyone disagrees, they can revert me or discuss it here. - Nunh-huh 12:18, 25 October 2014 (UTC)
