Abstract
A medium composed of 2% tryptone and 0.5% bile salts incubated at 44.5–45C is quite selective in the detection of faecal coliform bacteria. Production of indole after 24 hours of incubation constitutes the positive test. Through the use of large test tubes, samples of materials weighing 1 or more grams may be taken directly at the sites of operation within foods processing plants. The medium and the procedure are sensitive to 1 to 2 cells per inoculum, and it has detected Escherichia coli in samples yielding no colonies of coliform bacteria when plated at 1:10 on violet red bile agar.This publication has 3 references indexed in Scilit:
