"live microogranisms"

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

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.

Colorless, most widely dispersed of the Serratia species. 

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 organism is commonly isolated from human nasopharyngeal mucosa

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

This organism is normal flora of human skin.

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