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

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

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

This harmless insect parasitizes the Sarcophaga (flesh fly) pupae. Females usually lay 30–50 eggs in the pupae, which provide food for the Nasonia larvae when they hatch.

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

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

The nocturnal hermit crab uses “borrowed” shells to protect its relatively soft body, changing shells as it grows larger.

Both of these strains of Serratia marcescens are colorless mutants when plated alone, but when grown together, they produce a red pigment.

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.

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

These African clawed frogs are entirely aquatic and thrive in an ordinary freshwater aquarium. They are often used in developmental studies and genetic experiments.

All of our most popular crosses, already done for you. We'll do all the pre-work, so you can spend more time with your students.

The set Includes cultures of wild, white, brown, dumpy, vestigial, vestigial brown and sepia.

We fully guarantee the purity and viability of our Drosophila melanogaster cultures. A large, vigorous culture is shipped in a shatterproof plastic vial. To ship Drosophila cultures with living larvae we require 10 days' notice prior to use date. During very cold weather, adult flies may die but eggs and larvae usually survive. Allow cultures to come to room temperature before checking under low magnification for eggs and live larvae. Complete instructions are always included.
