Varietas Escherichiae est categoria inferna intra speciem illa habet adiuncta monodica quae distinguunt id de varietatibus aliis Escherichiae. Hae differentiae sunt saepe moleculares quamvis possunt mutare adiuncta physologiae bacterii.

Novae varietates Escherichiae mutant per inmutationem biologicam naturalem mutationis et nonnullae varietates potiriuntur adiuncta illa possunt esse inimica animali hospitali. Varietates virulentae naturaliter efficiunt diarrhoeam in hominibus adultis valentibus aliae includentes O157:H7 possunt efficire mortem sive morbum in senoribus aut populus immunocompromisus.

A strain of E. coli is a sub-group within the species that has unique characteristics that distinguish it from other E. coli strains. These differences are often detectable only on the molecular level; however, they may result in changes to the physiology or lifecycle of the bacterium. For example, a strain may gain pathogenic capacity, the ability to use a unique carbon source, the ability to inhabit a particular ecological niche or the ability to resist antimicrobial agents. Different strains of E. coli are often host-specific, making it possible to determine the source of fecal contamination in environmental samples.[6][7] Depending on which E. coli strains are present in a water sample, for example, assumptions can be made about whether the contamination originated from a human, other mammal or bird source.
New strains of E. coli evolve through the natural biological process of mutation, and some strains develop traits that can be harmful to a host animal. Although virulent strains typically cause no more than a bout of diarrhea in healthy adult humans, particularly virulent strains, such as O157:H7 or O111:B4, can cause serious illness or death in the elderly, the very young or the immunocompromised.[4]
