MacConkey Broth Purple is used for the detection and enumeration of fecal coliforms (37°C) and E. coli (44°C). This medium is not intended for use in the diagnosis of disease or other conditions in humans.

The replacement of neutral red used in the original formulation by bromocresol purple makes the color change caused by acid producing organisms easier to read.
