Bacteria Shigella versus EIEC

Still don't know how to differentiate Shigella from EIEC as both are invasive and both cause bloody diarrhea?
Can some one help me with that

Shigella is nonmotile, non lactose fermenter and do not produce H2S.
EIEC is motile, lactose fermenter and produces iridescent green sheen on EMB.
And other point which is suggestive of shigella is its extreme acid resistant nature.

E. coli is an indole-positive microorganism, which means that can make indole from tryptophan while Shigella cannot.
