This "many-headed" organism is a plasmodial slime mold commonly found in forests on decaying deciduous trees. Available in both plasmodial and sclerotial stages.

Demonstrates isogamous reproduction where gametes are similar in appearance and behavior. Make lectures and labs on protist reproduction clearer with our specially selected cultures that illustrate various reproductive phenomona.

This organism is an aerobic organism that is commonly found as part of normal human intestinal flora. It is pathogenic.

Ward's® Live Escherichia coli, Lactose Negative Culture

This organism is commonly isolated from human nasopharyngeal mucosa

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

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

Isolated from human nasopharynx, saliva, and sputum. Spontaneously agglutinates in saline.

Isolated from sewage, human intestines, and urinary tract infections. Spreading colonies are seen on agar growth medium. 

Frequent human isolate. Causes gastroenteritis.

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

From sewage and human intestine. Causes dysentery.
