Different strains of E. coli are often host-specific, making it possible to determine the source of fecal contamination in environmental samples. [13] [14] For example, knowing which E. coli strains are present in a water sample allows researchers to make assumptions about whether the contamination originated from a human, another mammal, or a ...
