The enteroinvasive E. coli (EIEC) strain NCDC 909-51 was isolated from the feces of a patient in Katwijk, The Netherlands around 1940. EIEC strains invade and multiply within intestinal epithelial cells, resulting in a dysentery-like enteritis in humans, similar to that caused by Shigella species. EIEC pathogenesis requires the expression of genes present both on the chromosome and on a large invasion plasmid, pINV (220,000 bp). The plasmid shares a significant degree of DNA homology with the virulence plasmid described in Shigella species, and is structurally and functionally equivalent.

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