Hemolysis, the rupture of red blood cells, is induced by certain species of streptococcal bacteria that produce extracellular hemolysin.  Observe this phenomenon with this set of 3 non-pathogenic species

Escherichia coli - Lactose neg

Grows on dead tissues. Novobiocin resistant (S. epidermidis and S. aureus novobiocin sensitive). 

Isolated from human nasopharynx. Presumably not related to N. sicca; some relation to N. gonorrhoeae. Often agglutinates in saline. 

Produces streptomycin. Branching mycelium and coenocytic hyphae. 

Isolated from human saliva, sputum, and intestine. No Lancefield group shown, alpha hemolysis.
