2. E. coli is a subgroup of the fecal coliform group. (Web site)

Pathogenic

1. The Coliform Index is used because it is difficult to test for pathogenic bacteria directly.

Water Supplies

1. Instead, water supplies are tested for an indicator of human or animal waste - coliform bacteria.

Water Supply

1. Remember that coliform bacteria in your water supply is a warning of contamination.

Escherichia Coli

1. Escherichia coli (E. coli) is the major species in the fecal coliform group.
2. Note: Some strains of Escherichia coli, which are a type of fecal coliform, can cause intestinal illness. (Web site)
3. Petrifilm plates were used for aerobic (PAC), coliform (PCC), and Escherichia coli (PEC) counts.

Contaminated

1. If a water supply is found to contain coliform bacteria, it may be contaminated by sewage or manure, and there is a risk of exposure to water-borne disease.
2. Studies have found that more than 40 percent of private water supplies are contaminated with coliform bacteria.

Warm-Blooded Animals

1. Coliform bacteria typically come from the intestines of warm-blooded animals and are considered as fecal pollution indicators. (Web site)

E-Coli

1. A more specific indicator is E-coli, which belongs to the Coliform group. (Web site)

Source

1. If only total coliform bacteria are detected in drinking water, the source is probably environmental.

Enterobacteriaceae Family

Counts

1. Total coliform counts give a general indication of the sanitary condition of a water supply. (Web site)
