Thermo Scientific™ Endo Agar

Description

Isolate and differentiate Enterobacteriaceae from clinical samples, potable water, dairy products and foods^{1, 2} with Thermo Scientific™ Oxoid™ Endo Agar. Originally designed for the isolation of typhoid bacillus³, Endo Agar is now mostly used for the differentiation of lactose fermenting and lactose non-fermenting intestinal organisms.

Isolate and differentiate Enterobacteriaceae with Endo Agar.

• Easy differentiation of lactose fermenting and non-lactose fermenting intestinal organisms.
• Ready-to-use convenience of prepared media.

Coliforms are commonly defined by their ability to ferment lactose rapidly, producing acid and gas, typically within 24 hours. The genera that would be commonly expected to belong to this group include Enterobacter, Klebsiella, Citrobacter and Escherichia, particularly Escherichia coli. However, species belonging to other genera, for example Erwinia andSerratia, can also ferment lactose, albeit slowly, and some strains of Citrobacter and Klebsiella, as well as Salmonella arizonae and Hafnia alvei, show delayed or variable fermentation ability.

Production of acid and aldehyde by lactose fermenting organisms, such as Escherichia coli, gives rise to the characteristic red coloration of the colony and the surrounding medium.
