A group of related bacteria whose presence in drinking water may indicate contamination by disease-causing microorganisms.
Coliform Organism similar to E. coli. Drinking water is often tested for coliforms, and a positive test is followed by the more specific (and difficult) test for E. coli or for ‘fecal coliforms'.
Bacteria that originates from the gut of animals. When found in water, it can indicate sewage, industrial use or other sources of contamination.
Type of bacteria - main habitat being human intestinal tract.
A bacterial component used as an indicator of fecal contamination, which may lead to human health risks if exposed to contaminated waters.
A group of bacteria found in the intestines of warm-blooded animals (including humans) and also in plants, soil, air and water. Fecal coliforms are a specific class of bacteria which only inhabit the intestines of warm-blooded animals. The presence of coliform bacteria is and indication that the water is polluted and may contain pathogenic organisms.
Widely distributed micro-organisms found in the intestinal tract of humans and other animals and in soils. Their presence in water indicates fecal pollution and potentially dangerous contamination by disease-causing micro-organisms.
One type of bacteria. The presence of Coliform-group bacteria is an indication of possible pathogenic bacterial contamination. The human intestinal tract is one of the main habitats of Coliform bacteria. Fecal coliforms are those coliforms found in the feces of various warm-blooded animals: whereas the term “Coliform” also includes other environmental sources.
a bacterium allied to a group found in the gut.
Any of a number of organisms common to the intestinal tract of man and animals, used as an indicator of water pollution.
a group of bacteria used as indicators of microbiological contamination
A specific class of bacteria found in the intestines of warm-blooded animals. The presence of coliform in water indicates that the water is polluted and may contain disease-causing (pathogenic) microorganisms.
Water-borne bacteria, often associated with pollution.
Rod-shaped bacteria originating from the intestinal tract.
The recommended level is 0 per 100 ml or absence/100 ml sample. Coliform bacteria are used as indicator organisms to ascertain quality of potable water. The presence of coliform bacteria indicates that disease-causing bacteria may be present.
A group of bacteria commonly found in the environment. They are an indicator of potential contamination of water. Adequate and appropriate disinfection effectively destroys coliform bacteria.
Bacteria Non-pathogenic microorganisms used in testing water to indicate the presence of pathogenic bacteria
