Normal flora of the mouth and throat. Lancefield group K, gamma hemolysis. 

Noted for capsular swelling. Causes pneumonia and urinary tract infections.

This organism is a common environmental isolate, and can be found in soil as well as in industrial settings.

Beta hemolysis on blood. Causes wound infections and septicemia. 

This organism is commonly isolated from soil or water, and produces a pink or rose colored pigment.

Isolated from milk and cheese products. Can be used to ferment milk. 

Isolated from human nasopharynx, saliva, and sputum. Spontaneously agglutinates in saline.
