Fecal coliforms

- g-, non-spore forming, fac anaerobic rods - ferment lactose to produce acid and gas in EC broth between 44-45 C - a fecal coliform tests is a test SPECIFICALLY for E. coli along with some Klebsiella spp and Enterobacter spp - specificity as fecal contaminants is much higher than coliforms - non-fecal coliforms eliminated due to the use of high temperature in selective broth containing lactose - lactose fermentation with gas production is a presumptive test
