"live microogranisms"

Isolated from human intestine, this organism is known for its distinctive putrefactive odor.

Colorless, most widely dispersed of the Serratia species. 

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

A collection of some of the strains of Escherichia coli needed to grow various coliphages (available separately).

Frequent human isolate. Causes gastroenteritis.

From sewage and human intestine. Causes dysentery. 

Ideal for use as a model system, this free-living nematode has biological processes similar to those of other animals. The transparent animal normally inhabits soil.

The presence of A. viscolactis in milk is a common cause for sliminess or "ropiness".

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 pathogenic organism is sometimes isolated from hay and grass.

Isolated from human nasopharynx. Presumably not related to N. sicca; some relation to N. gonorrhoeae. Often agglutinates in saline. 

This organism is commonly isolated from human nasopharyngeal mucosa

This organism is normal flora of human skin.

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

A quick and colorful demonstration of Mendel’s Law of Segregation.
