Total Coliforms|Fecal Coliforms|E- Coli-Defines

Total Coliforms:Coliforms are a group of gram-negative, rod-shaped bacteria that are nonpathogenic and nonspore forming. The most common coliform genera are Escherichia, Enterobacter, Citrobacter,Serratia, and Klebsiella, with E. coli being the most abundant in the gut of humans and other warm-blooded animals. Coliform bacteria are identifiable by their ability to ferment lactose to produce acid and gas within 48 [....]
