"bacteria"

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). 

Produces orange pigments. 

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

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

Found on dental plaque, implicated in cavities. No Lancefield group shown, gamma hemolysis. 

E. coli with JM101 can be transformed with pUC8 plasmid to become resistant to Ampicillin and to metabolize lactose

This pathogenic organism is sometimes isolated from hay and grass.

Normal flora of respiratory tract. Beta-lactamase positive. Also known by the name Branhamella catarrhalis
