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).

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.

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.

Hemolysis, the rupture of red blood cells, is induced by certain species of streptococcal bacteria that produce extracellular hemolysin.  Observe this phenomenon with this set of 3 non-pathogenic species

Two strains of Escherichia coli (donor and host) with complementary sensitivities to Ampicillin and Streptomycin. Watch them trade traits via conjugation.

Isolated from human urinary tract and wound infections, this organism is identifiable by its characteristic putrefactive odor.
