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

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

Isolated from sewage, human intestines, and urinary tract infections. Spreading colonies are seen on agar growth medium. 

Both of these strains of Serratia marcescens are colorless mutants when plated alone, but when grown together, they produce a red pigment.

From sewage and human intestine. Causes dysentery. 

Beta hemolysis on blood. Causes wound infections and septicemia. 

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

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

No Lancefield group shown, alpha hemolysis. Bile solubility test positive, optochin sensitive. Causes pneumonia. 

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

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

This organism is normal flora of human intestine and may be pathogenic in humans. This organism will grow in Sodium chloride solution.

The presence of A. viscolactis in milk is a common cause for sliminess or "ropiness".

This pathogenic organism is sometimes isolated from hay and grass.

This organism is occasionally isolated from soil, but most frequently from smegma- a secretion from male and female genitalia.

This organism can be isolated from many human urinary tract infections, as well as polluted water and sewage. It is commonly identified by its distinctive grape-like smell (trimethylamine) or because it can turn the agar light green due to production of a blue pigment (pyocyanin).
