WURTZ MEDIUM

The family Enterobacteriaceae consists of a large group of organisms all of which ferment glucose. Those, which ferment lactose, are grouped together as ?coliform bacteria?. Pathogenic serotypes of Escherichia coli present a particular problem and their isolation has always been a difficult process.
Wurtz Medium is a non-selective medium employed for the growth, and the differentiation of Enterobacteriaceae from clinical samples, especially when suspected with the presence of pathogenic E. coli.
