Question

Quizplus · Accepted Answer

E. coli is a normal inhabitant of the intestinal tract, and during delivery, the infant may be exposed to bacteria in the birth canal, leading to the possibility of E. coli infection. Breast milk and formula are not typical sources of E. coli, and contact with humans alone is not a sufficient explanation.
