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

This organism is normal flora of human skin.

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

Clever alternative to using colony counters.

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. 

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.

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.

Isolated from milk and udders of cows. Lancefield group B, beta hemolysis. Causes infection of the female genital tract, maternal septicemia, neonatal infections. Camp test positive; resistant to bacitracin.

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

Make the invisible visible. A safe and simple way to teach pollution and contamination, this kit allows students to detect microscopic microbes in samples of air and water they collect.
