title: Evaluation of indoxyl-beta-D-glucuronide as a chromogen in media specific for Escherichia coli.
abstract: Indoxyl-beta-D-glucuronide (indoxyl) was evaluated as a specific chromogen for detection of Escherichia coli by the membrane filter method. In all, 413 colonies were tested from the indoxyl-supplemented media, yielding 93.3% confirmation, as E. coli. Compared with the indoxyl medium, other media gave either much lower recovery with high verification or equal recovery with poor verification.
