Escherichia coli (E. coli), strain A was isolated from human clinical specimen in Washington state, 1989.

E. coli, strain A is reported to be resistant to streptomycin, sulfisoxazole and tetracycline.

E. coli, strain A and many other enterohemorrhagic E. coli (EHEC) strains release potent toxins, similar to those of Shigella dysenteriae, which can cause severe intestinal, kidney and central nervous system disease. E. coli, strain A carries virulence-associated genes located on both the chromosome and plasmid of the organism.

The presence of plasmid pO157 and chromosomal virulence markers stx1, stx2 and eaeA have been confirmed by PCR amplification from extracted DNA.

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

Note: If homogeneity is required for your intended use, please purify prior to initiating work.
