I think under "virulence factors" it's just C5a peptidase (meaning it degrades the complement anaphylotoxin C5a released in the complement cascade) rather than anti-C5a peptidase (meaning it degrades the portion of the cell wall on S. pyogenes that degrades C5a). Just a thought.—Preceding unsigned comment added by 209.90.69.50 (talk • contribs)

Yes, that's correct. I've removed the anti-. 12:48, 15 December 2006 (UTC)

[edit] Biolevel?

What biolevel is this bacterium? Ace ofgabriel 17:09, 16 February 2007 (UTC)

  • Should be a BSL-2 (i.e. same level as S. aureus, V. cholera, Proteus spp, etc.). -- MarcoTolo 01:00, 17 February 2007 (UTC)


[edit] Hyaluronic acid capsule

Doesn't S. pyogenes have a hyaluronic acid capsule that's relevant in disease? Should this be mentioned somewhere? 203.5.70.1 14:28, 22 March 2007 (UTC)

Yes, that's true. The composition of the capsule is now stated. NighthawkJ 03:24, 28 April 2007 (UTC)
