Fig 1. A, The typical dry, lactose-positive Escherichia coli growing on MacConkey
(MAC) agar. Note the pink precipitate surrounding the individual colonies. B, Mucoid
colonies of E. coli growing on MAC agar. C, Non–lactose-fermenting E. coli compared

Comparison of the colony morphology of Escherichia vulneris and a yellow-pigmented Escherichia hermannii on MacConkey agar.
Fig 2. Comparison of the colony morphology of
Escherichia vulneris and a yellow-pigmented Escherichia
hermannii
on MacConkey agar. Escherichia vulneris may also
produce a yellow-pigmented colony, but the yellow is more
prevalent in E. hermannii.
