Bacteria that are present in the gut or the feces of warm blooded animals; they are indicators of possible sewage pollution.

Technically, all the facultative anaerobic gram negative non-spore forming rod shaped bacteria that fermet lactose in EC medium with gas production within 24h at 44.5 degrees °C

Coliform bacteria (microorganisms) found in the intestinal tract of warm-blooded animals (including humans). Unlike total coliforms, which include a number of normal soil inhabitants that are harmless, fecal coliforms are more reliable indicators of fecal contamination, which may result in the spread of intestinal disease.

Bacteria found in the intestinal tracts of animals. Their presence in water or sludge is an indicator of pollution and possible contamination by pathogens.

Bacteria found in the intestinal tracts of mammals. Their presence in water or sludge is an indicator of pollution and possible contamination by pathogens.

Bacteria found in the intestinal tracts of mammals. Their presence in water or sludge is an indicator of pollution and possible contamination by pathogens.

Bacteria found in the intestinal tracts of all  mammals.  Their presence in water is an indicator of pollution and possible contamination by pathogens (also see coliform bacteria).

"Gram-negative, non spore-forming, oxidase-negative, rod-shaped facultative anaerobic bacteria that ferment lactose (with β-galactosidase) to acid and gas within 24–48h at 36±2°C. Not specific in [..]

Common, harmless forms of bacteria that are normal constituents of human intestines and found in human waste and in wastewater. Fecal coliform bacteria counts are used as an indicator of the possible presence of pathogenic microbes. (see E.coli above).

Bacteria present in the feces of humans and other warm-blooded animals but rare or absent in unpolluted waters. Fecal coliform bacteria should not be found in sources of drinking water. Their presen [..]

Bacteria found in the digestive tract of warm-blooded animals. Contamination of fecal coliform bateria is indicative of human, pets and/or wildlife feces deposition in the aquatic ecosystems. Although [..]

Bacteria common to the intestinal tract of mammals. Indicates biowaste from livestock or humans and may be a sign of disease-causing pathogens.
