Wurtz Medium, 5 kg

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 (1). The medium contains meat peptone and beef extract, which provide essential growth nutrients. Lactose is the fermentable sugar and bromothymol blue acts as pH indicator. Lactose fermenters form yellow coloured colonies, while the lactose-nonfermenting Enterobacteriaceae grows as blue colonies due to the alkalization of the medium. Storage and Shelf-life: Store below 30°C in tightly closed container and the prepared medium at 2 - 8°C. Use before expiry date on the label. Reference: 1. Corry J. E. L., Curtis G. D.
