E. coli is a gram-negative, rod-shaped bacterium which occurs singly or in pairs. It is a major facultative inhabitant of the large intestine.

The enterohemorrhagic E. coli (EHEC) strain H414-36/89 was isolated from a patient with hemorrhagic colitis in Germany. E. coli H414-36/89 and many other EHEC strains encode potent toxins, similar to those of Shigella dysenteriae, which can cause severe intestinal, kidney and central nervous system disease. The large plasmid of E. coli H414-36/89 carries one copy of the gene for Shiga-like toxin type II (SLT-II) and two copies of the gene for an SLT-II-variant-type toxin. E. coli H414 36/89 has been shown to be highly virulent in a mouse model of infection.

Each vial contains approximately 0.5 mL of bacterial culture in 0.5X Tryptic Soy Broth supplemented with 10% glycerol.
