"Ward's Phenomena"

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).

Includes Examples of the Three Basic Morphological Types

Organisms with Characteristics of Two Kingdoms

Water mold and fish parasite. Demonstrates sporangia and oospores. Grows on wheat seed, cucumber seed, or hemp seed in water environment. Reproduces sexually and asexually. Incubation temperature 25°C.

Cell walls made of cellulose; feeds by extending hyphae into host's tissue.

Specially Prepared “Real-Life” Combinations
The world is teeming with a wide variety of microlife, making studying samples of pond water complicated especially for the beginning student. To lessen the confusion, WARD’S has prepared different culture mixes that reflect protist combinations that occur in the real world, yet eliminates the hundreds of other life-forms found in a collected sample. Comes with a dichotomous key and either the Working with Algae or the Working with Protozoa manual. Supplied in a single jar.

Contents: Amphidinium, Coccolithophora, Dunaliella, Ectocarpus, and Prorocentrum.

Taking their name from the bluish pigment that most of these organisms share, each jar contains a broad sample of several types of cyanobacteria.
