"Ward's® Thermochemistry In The Bag Inquiry Demonstration Activities"

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

This organism can be isolated from many human urinary tract infections, as well as polluted water and sewage. It is commonly identified by its distinctive grape-like smell (trimethylamine) or because it can turn the agar light green due to production of a blue pigment (pyocyanin).

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

Lancefield group A, beta hemolysis. Sensitive to bacitracin. Causes strep throat, rheumatic fever, and scarlet fever.

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.

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

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

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

Three Morphology Types in One Tube

Supplied as tube cultures. Comes with culture and handling instructions, as well as the manual Working with Fungi.

Eight strains: a1 (HAO), α1 (HBO), a2 (HAR), α2 (HBR), a3 (HAT), α3 (HBT), a4 (HART), α4 (HBRT).

Fascinate students with some of the simplest light-producing organisms

Cellular slime mold. Demonstrates amoeboid state, pseudoplasmodial state, and fruiting body, or sorocarp. Found in woodland soil in decomposing vegetation where bacteria are abundant. Incubation temperature 25°C. Plate cultures grown with Enterobacteria as food source; freeze-dried cultures include food source.

Characterized by an amoeboid stage (lacking cell walls) and a fungus-like reproductive structure.

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.

Freshwater. Unicellular; homothallic strain. Basic culture solution. Characterized by green plastids and cell walls composed of cellulose.

Freshwater. Unicellular; pennate, with bilateral symmetry. Basic culture solution.

Characterized by shells (tests) made of silica, in two parts.
