When it comes to the issue of Escherichia coli, it is an important indicator in the Online Monitoring of Medical Wastewater. So, what’s the difference between total bacterial count and coliform bacteria?

The total bacterial count can reflect the bacterial contamination of water bodies, but it cannot indicate the source of contamination. Therefore, it is necessary to combine the population of Escherichia coli to determine the source of contamination and the safety situation in the water body. Coliform bacteria, on the other hand, are important vectors for the transmission of intestinal diseases and are fundamental indicators of fecal contamination.

In addition, there is also a certain relationship between the total number of bacteria and coliform bacteria.

1.Both are routine indicators for the total microbial detection of food or water quality.

2.Although the total bacterial count in actual work includes the total number of colonies of some thermophilic aerobic or facultative anaerobic bacteria that can develop on nutrient AGAR, coliform bacteria can also grow well under the above conditions. Therefore, the total bacterial count value actually includes the value of coliform bacteria.
