title: Practical substitution for the indol, methyl red, Voges-Proskauer, citrate system.
abstract: A substitution for the indole, methyl red, Voges-Proskauer, citrate system is proposed. The scheme employs indole and ampicillin susceptibility tests routinely and uses selectively three other media for six reactions.
