Hektoen enteric agar is a medium designed for the isolation and recovery
of fecal specimens belonging to the Enterbacteriaceae family,
especially Salmonella and Shigella. It can differentiate between
bacteria that ferment lactose and those that don't. Acid produced from
fermenting lactose imparts a yellow-orange color to the medium due to
the presence of a pH indicator. Non-lactose fermenters do not
significantly change the color of the medium. HE agar can also detect
the production of hydrogen sulfide gas, which turns parts of the medium
black.
