Live Specimens

Normal flora of respiratory tract. Beta-lactamase positive. Also known by the name Branhamella catarrhalis

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

This yellow, shiny organism is known to cause wound infections and more famously, toxic shock syndrome.

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

Isolated from human saliva, sputum, and intestine. No Lancefield group shown, alpha hemolysis.

Hemolysis, the rupture of red blood cells, is induced by certain species of streptococcal bacteria that produce extracellular hemolysin.  Observe this phenomenon with this set of 3 non-pathogenic species

Deuteromycete. Causes thrush, candidiasis. Multiplies by budding. Forms germ-tubes in serum cultures. Incubation temperature 37°C. Potato dextrose agar growth medium. Note: Pathogen.

Zygomycete. Dung Mold. Mating strain; cross with Mucor heimalis (+) for zygospore formation. Incubation temperature 25°C. Potato dextrose agar growth medium.

Ascomycete. Host for rDNA. Incubation temperature 30°C. Sabouraud dextrose/YM agar growth medium.

Produce High-Titer T-Series Coliphages Without Setting Up an Aeration System

Poecilia reticulata.

Pathway between plant cells.

Formalin Preserved

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

A collection of some of the more popular forms of coliphage. The successful culture of coliphage requires growing in the appropriate host bacterium (available separately)

Cellular slime mold. Demonstrates amoeboid state, pseudoplasmodial state, and fruiting body, or sorocarp.
