Coliform Bacteria in Drinking Water.

 Coliform bacteria can be defined as facultatively anaerobic, Gram-negative and non-spore-forming rods shape bacteria that ferment lactose vigorously to acid and gas at 35 ± 2 °C temperature within 24 or 48 h. Coliform bacteria often are considered as indicators of fecal contamination and pathogenic enteric bacteria.Coliform bacteria generally belong to four genera of the Enterobacteriaceae, Citrobacter freundii, Enterobacter cloacae, Enterobacter aerogenes, E. coli, and  Klebsiella pneumonia.

Coliform bacteria will not likely cause illness but their presence in the drinking water indicates that the disease-causing organisms could be in the water system. Pathogens that can be contaminate water supplies which may be come from the feces of humans or animals.
