A rapid and simple method for distinguishing colonies of from those of and Free

Abstract

Summary.

A rapid and simple method is described by which colonies of can be distinguished from those of and and other non-lactose-fermenting organisms growing on MacConkey’s agar or desoxycholate citrate agar. The method is based on the ability of to produce urease constitutively. The enzyme was detected by the degradation of urea by the inoculum, thereby creating an alkaline reaction on H-indicator paper.
