organisms associated with the intestines of warm-blooded animals that are used to indicate the presence of feces in water and the potential presence of disease-causing organisms
Indicators of bacterial contamination of fecal origin used to assess the bacteriological quality of waters.
A group of organisms common to the intestinal tracts of humans and animals. The presence of fecal coliform bacteria in water, wastewater, or biosolids is an indicator of pollution and possible contamination by pathogens.
Total coliform bacteria are a collection of relatively harmless microorganisms that live in large numbers in the intestines of man and warm- and cold-blooded animals. A specific subgroup of this collection is the fecal coliform bacteria, with the most common member being Escherichia coli. These organisms may be separated from the total coliform group by their ability to grow at elevated temperatures and are associated only with the fecal material of warm-blooded animals.
Bacteria from the intestines of warm-blooded animals. Most of the bacteria are not in themselves harmful, so they are measured or counted as an indicator of the possible presence of harmful bacteria.
Bacteria that are present in the intestine and feces of warm-blooded animals. They are often used as indicators of the sanitary quality of water. There concentrations are expressed as numbers of colonies per 100 mL of sample.
A group of bacteria which are used as indicators of possible sewage or waste contamination because they are commonly found in human and animal feces.
a type of coliform bacteria found in the intestines of humans and other warm-blooded animals that aids in the digestion process. It is used as an indicator of fecal contamination and the possible presence of pathogens.
An indicator of the possible presence of harmful organisms in water. Fecal coliform bacteria levels in rivers and lakes usually rise for a few days following rain. The U.S. Environmental Protection Agency recommends no contact with water containing more than 200 colonies of fecal coliform bacteria per 100 milliliters.
Specific coliform bacteria associated with the digestive tract of warm-blooded animals.
Bacteria that are present in the gut or the feces of warm blooded animals; they are indicators of possible sewage pollution.
A group of organisms found in the intestinal tracts of people and animals. Their presence in water indicates pollution and in large numbers may pose a health hazard.
A group of bacteria which are found as the predominant normal inhabitants in the gastrointestinal tract of warm blooded animals. These bacteria are excreted in large numbers in the faeces of warm blooded animals and therefore are used as indicator of recent faecal contamination in an area.
A group of bacteria found in the intestinal tract of humans and animals, and also found in soil. While harmless in themselves, coliform bacteria are commonly used as indicators of the presence of pathogenic organisms and other disease-causing bacteria, such as those that cause typhoid, dysentery, hepatitis A and cholera. Measured in number of bacteria per 100 milliliters of water. Failing septic systems and runoff from feedlots are common sources of fecal coliform in water samples.
a class of bacteria that is unique to the intestinal tracts of warm-blooded animals and is used as an indicator of the presence of human waste in the aquatic environment.
Bacteria that originate in the intestinal tract of a mammal. Not all fecal coliform bacteria cause disease, but this relatively simple test is used as an indicator that fecal matter is getting into the waterbody, and that other potentially harmful contaminants may be also be entering the waterbody. The main sources of these bacteria are from animal and human waste. Animal sources of bacteria include feedlot and manure runoff, urban runoff, and wildlife. Improperly treated human waste may come from overflows from sewage treatment systems in cities and towns, unsewered areas with inadequate community or individual wastewater treatment, or a single home with a failing septic system.
Microorganisms that usually occur in the intestinal tract of "warm blooded" animals (including humans), e.g. Escherichia coli; commonly used as an indicator of contamination, (see also Most Probable Number.)
Bacteria found in the intestinal tracts of mammals. Their presence in water or sludge is an indicator of pollution and possible contamination by pathogens.
