Media for ‘Total’ Enterobacteriaceae, Coliforms and Escherichia coli

International Journal of Food Microbiology, 1995
Selective and enrichment media for the isolation and enumeration of 'total' Enterobacteriaceae, coliforms, faecal coliforms and E. coli from foods are described. The effects of time and temperature of incubation are discussed. Reports of some comparative studies of these media and factors to be considered in the selection of media for this group of ...

Escherichia coli and Total Coliforms in Water and Sediments at Lake Marinas

Environmental Pollution, 2002
Escherichia coli, a fecal coliform, and total coliforms were monitored between September 1999 and October 2001 in five marinas at Lake Texoma, located on the Oklahoma and Texas border. The general trend was that densities of E. coli were lower in the summer season due to the lower loading of fecal material into Lake Texoma and the ecological conditions

Nematodes as a source of total coliforms in a distribution system

Canadian Journal of Microbiology, 2007
In a distribution system of a large North American city, recurring total coliforms and atypical coliforms were detected at the exit (distribution pumps) of a storage reservoir. The presence of total coliforms and atypical coliforms was noted when the pumps were in operation and the water temperature was higher than 18 °C.

Total Coliform Rule Brain Teaser

Journal AWWA, 2009
This brain teaser deals with a hypothetical situation where a small public water system (one that is normally required to only assay one routine total coliform sample during a month) will have to assay five samples in one month's time. The five samples can be either one routine and four repeat samples or five routine samples and no repeats.
