Isolated from soil. Forms red pigment (best on high carbohydrate medium) and has oval eccentric spores. 

Used for culturing Dictyostelium discoideum (cellular slime mold). 

From soil and water rich in minerals. Organism of putrefaction.

Colorless, most widely dispersed of the Serratia species. 

All microbial cultures undergo an extensive quality control program prior to releasing for sale, so they are guaranteed for purity as well as for species.

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.

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. 

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. 

isolated from human intestine. Lactose positive and sucrose positive after a few days’ growth. Causes a mild form of dysentery.

Beta hemolysis on blood. Causes wound infections and septicemia. 

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