Part A) What barrier was breached by the pathogen?
Part B) Describe how that barrier works and how it can prevent mom's pathogens from infecting the fetus.
A tiny 1-kg (2.2-pound) female neonate (newborn) was born two months premature. The baby had extreme difficulty breathing and
had to be intubated (a breathing tube inserted). The mother, at the time of admission, had complained of mild diarrhea and
abnormal abdominal pain unrelated to her pregnancy. The infectious disease doctor who was called in to consult on the case
immediately recognized the likely problem and ordered blood cultures be performed on the infant. The infant was also started on
intravenous antibiotics. Two days later, the lab reported finding a Gram-positive bacillus-Listeria monocytogenes-in the infant's

cheese contaminated with this pathogen and developed listeriosis. The organism entered the…
