You could plate your sample (or dilutions of it) on EMB (eosin
methylene blue) agar.  This particular agar is specialized for
detecting E. coli.  On these plates, E. coli takes on a green, metallic
sheen.  So, you'd count the colonies that appeared this way, and ignore
anything else that might grow up.

Any other ideas out there?
