This spore-forming, thermophilic organism is commonly used for germicidal and sporicidal testing due to its ability to withstand higher-than-normal temperatures.

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

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

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

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

Capsules produced in milk. Psychrophilic (prefers low temperatures), produces yellow pigments. 

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

Frequent human isolate. Causes gastroenteritis.

Ames test strain for detecting carcinogens. Causes infection in humans. 

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.
