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

This pathogenic organism is sometimes isolated from hay and grass.

This organism is commonly isolated from soil or water, and produces a pink or rose colored pigment.

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

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

This organism is commonly recovered from soil and water. As normal intestinal flora, it can also usually be found in sewage.

This organism can be isolated from soil, wounds, and intestinal tracts of humans. It digests protein and is known for its strong, distinctive odor.

In this lab, students perform a Gram stain on various species of bacteria.

This organism is a common environmental isolate, and can be found in soil as well as in industrial settings.

Beta hemolysis on blood. Causes wound infections and septicemia. 

All-purpose medium that supports the growth of a variety of microorganisms.

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

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

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

Observe a relationship between two organisms that together produce an effect they could not achieve individually.

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.
