Indicating microorganism
Web"Indicator" Organisms Water pollution caused by fecal contamination is a serious problem due to the potential for contracting diseases from pathogens (diseasecausing organisms). Frequently, concentrations of pathogens from fecal contamination are small, and the number of different possible pathogens is large. Indicator bacteria are types of bacteria used to detect and estimate the level of fecal contamination of water. They are not dangerous to human health but are used to indicate the presence of a health risk. Each gram of human feces contains approximately ~100 billion (1×10 ) bacteria. These bacteria may include species of pathogenic bacteria, such as Salmonella or Campylobacter, associated with
