Talk:Spirochaete

genera of spirochaetes

I believe the information in the spirochaetes article is out of date and that the 3 genera are now known as;

1. Borrelia 2. Leptospira 3. Brachyspira - veterinary species were formally known as Serpulina and before that as Treponema of which T. paracuniculi caused rabbit syphilis

Brachyspira

B. hyodysenteriae causes swine dysentery, a mucohaemorrhagic fibronecrotic colitis causing severe dehydration, loss of condition and death in weaned pigs aged 7 to 20 weeks. Can be seen using Gram stain under a light microscope. It is anaerobic, produces a haemolysin (similar to Streptolysin S) resulting in a complete haemolytic zone on blood agar (used as differential diagnosis from B. innocens a similar but non-pathogenic spiraochaete). Pathogenesis - bacteria colonise colon crypts and invade goblet cells resulting in an overproduction of mucus. Also causes epithelial cell necrosis and erosion. Diarrhoea and dehydration results from impaired ability to absorb water. Disease depend on the presence of other anaerobic or facultative anaerobes

B. pilosicoli is a weakly haemolytic spirochaete. May be the organism responsible for many field cases of spirochaetal diarrhoea or porcine intestinal spirochaetosis. It is a milder form of swine dysentery showing signs of moderate diarrhoea and reduced growth rate.Cdurose 15:10, 9 November 2006 (UTC)

Family: Leptonema

When I click on the side link Leptonema, It links me to a plant family. 76.205.65.198 01:05, 11 May 2007 (UTC)

Thanks for catching that - I've removed the incorrect link. -- MarcoTolo 01:42, 11 May 2007 (UTC)

Distinction?

Should we put in anything about the distinction of genus Spirochaete from genus Spirillum? I know I was wondering about it a bit. Elfred (talk) 22:19, 14 April 2008 (UTC)

Pronounciation

Could someone add a pronounciation to this article? I've been wondering for a while....68.49.50.181 (talk) 01:13, 3 May 2009 (UTC)

yeah, is it spyro or speero? (ipa = spaɪoʊ or spiːroʊ that's an i without the dot and the iː is one character)

is it chayt or cheet or chet? (tʃeɪt or tʃiːt or tʃɛt yes ch is like tsh)

chayt or shayt? (tʃeɪt or ʃeɪt)

chayt or chayty? (tʃeɪt or tʃeɪtɛ)

guide to IPA characters: Help:IPA_for_English or you can just copy whats in the parens. OsamaBinLogin (talk) 20:23, 8 March 2014 (UTC)

Lynn Margulis Comment

Why does this article list a pretty random factoid about a hypothesis that's not accepted in the scientific community? Listing it here gives the idea more credence than it deserves. Lynn Margulis places a lot more emphasis on symbiosis than what is currently accepted in the scientific community. —Preceding unsigned comment added by Shalomamigos (talk • contribs) 00:43, 20 June 2010 (UTC)

Spirochaete → Spirochete – This Google ngram and Google Trends chart show a definite preference for spirochete Marcus Qwertyus (talk) 12:33, 25 November 2012 (UTC)

• Oppose per WP:ENGVAR. Compare the entry for spirochaete ("US spirochete") in Oxford Dictionary of English with the entry for spirochete ("also spirochaete") in Merriam-Webster's Collegiate. SSR (talk) 07:06, 27 November 2012 (UTC)
• Oppose - and WP:ENGVAR is as far as one needs to look, without question. -- Scray (talk) 14:39, 27 November 2012 (UTC)

Leptonema — a flowering plant!?!

The Leptonema link in this article erroneously goes to a Wikipedia page on a flowering plant: "Leptonema is a genus of flowering plant belonging to the family Phyllanthaceae" Drgao (talk) 14:42, 5 January 2013 (UTC)

Does shape give any advantages?

Does the spiral shape give any advantages? If so, this should be mentioned in the article.

I ask because activists for changes in policy regarding chronic Lyme disease claim that the spiral shape allows the bacteria to drill into tissue. I'm rather skeptical about this claim. SlowJog (talk) 19:16, 21 August 2013 (UTC)

Change in image caption

This edit presumes much about the image. Looking at the contributor's other submissions, the distance between numbered ticks varies (I see 11 and 20 microns, for example). While it is possible that this is an error, the image page on Commons indicates 11 at least twice. If in doubt, ask the contributor, but the only source we have for now is the record of submission. -- Scray (talk) 22:13, 21 August 2013 (UTC)

You are correct. After looking into it, I see the scale is built into the user's microscope, and the scale changes with magnification. It can be almost any size, because it depends on the magnification used. SlowJog (talk) 04:39, 16 September 2013 (UTC)
