Nôvo meio para isolamento de enterobacteriáceas e diferenciação simultânea das colônias de Proteus e Providência

Abstract

A new culture medium for the isolation of Enterobacteriaceae is proposed. It is based on the property common to Proteus and Providence of deaminating phenylalanine. In the culture medium here proposed the colonies of the mentioned microorganisms show a characteristic brown colour. Colonies of other Enterobacteriaceas show a quite different aspect.
