I've created these categories

[| Category:Bacteria displaying Alpha hemolysis (α-hemolysis)]
[| Category:Bacteria displaying Beta hemolysis (β-hemolysis)]
[| Category:Bacteria displaying gamma hemolysis (γ-hemolysis)]

I don't think these categories are available; because hemolytic characters are not always identical in species. The hemolytic characters depend on rather strains than species. For example, see [1]. Str. mutans displays alpha/gamma (and rarely beta) hemolysis. E. coli, Staph. aureus, and other many species do so. Str. pyogenes, Str. agalactiae and Str. pneumoniae, whose hemolytic characters concomitant their species, are rather exceptional, I think. --Y tambe (talk) 03:56, 15 June 2008 (UTC)

is it me - or do the images conflict when describing alpha and beta hemolysis?

the hemolysin is located on the red blood cells. (AL-BAQAAWEE)

Confusing?

Especially in the beta section, It mentions that streptolysin is the cause of beta hemolysis. But surely its not the only cause; I'm not an expert on this, but I'm pretty sure staph aureus is a beta hemolytic bacteria that does not produce streptolysin. And to continue this thought, this article focuses almost exclusively on streptococcal bacteria. Maybe the language could be tweaked to sound more balanced? — Preceding unsigned comment added by 137.43.188.184 (talk) 15:59, 16 March 2012 (UTC)

Being balanced would be misleading. Hemolysis type is useful in the identification of streptococcal species, not other species. Essentially, the "flow" is: gram positive vs. negative ->strep vs staph (colony morphology) -> hemolysis type. Staph causes hemolysis, but hemolysis is *not* used in the routine identification of staph species, whereas it *is* used routinely in the identification of strep species. - Nunh-huh 03:36, 17 March 2012 (UTC)
