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. 

Beta hemolysis on blood. Causes wound infections and septicemia. 

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

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).

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 yellow, shiny organism is known to cause wound infections and more famously, toxic shock syndrome.

Lancefield group A, beta hemolysis. Sensitive to bacitracin. Causes strep throat, rheumatic fever, and scarlet fever.
