Determination of Escherichia coli contamination with chromocult coliform agar showed a high level of discrimination efficiency for differing fecal pollution levels in tropical waters of Kampala, Uganda

Escherichia coli, total coliforms, fecal coliforms, and sulfite-reducing an aerobic spore formers from different polluted sites in a tropical environme nt were determined in order to test for their indication ability for fecal contamination. Quantification of E. coli contamination with Chromocult coli form agar proved to be efficient and feasible for determining fecal polluti ons in the investigated area within 24 h. The other microbial parameters sh owed a lower ability to differentiate sites and cannot be recommended for m onitoring fecal pollution in the studied tropical surface waters.
