Fecal coliform, like other bacteria, can usually be inhibited in growth by boiling water, treating with chlorine, or UV disinfection. Washing thoroughly with soap after contact with contaminated water can also help prevent infections. Gloves should always be worn when testing for fecal coliform.
Coliform bacteria are defined as either ... can be distinguished from most other coliforms by its ability to ferment lactose at 44 °C in the fecal coliform test, ...
Fecal coliforms are more useful as indicators in recreational waters than total coliforms which include species that are naturally found in plants and soil; however, there are even some species of fecal coliforms that do not have a fecal origin, such as Klebsiella pneumoniae. Perhaps the biggest drawback to using coliforms as indicators is that ...

As the summer season gets underway, a new report finds that many coastal U.S. waterways, including popular beaches for swimming, are contaminated with unsafe levels of fecal bacteria.
The IMViC tests are a group of individual tests used in microbiology lab testing to identify an organism in the coliform group. A coliform is a gram negative, aerobic, or facultative anaerobic rod, which produces gas from lactose within 48 hours. The presence of some coliforms indicate fecal contamination.
High levels of fecal bacteria, specifically enterococci, are commonly found in the intestines, and animal excrement was detected in water samples from the New Jersey beaches on July 1.
The presence of indicator bacteria is measured in a variety of ecosystems and sometimes alongside other measurements. In the Great Lakes, a study was conducted testing for both fecal indicator bacteria (FIB) concentrations and pathogen gene markers. [7] The FIB measured in this study included fecal coliform bacteria, E. coli, and enterococci. [7]
