Presenters on the Morning News Channel That You Watch Alert

Presenters on the morning news channel that you watch alert consumers to a food recall. A particular brand of ice cream has tested positive for Listeria monocytogenes, an organism that causes asymptomatic or relatively mild disease in otherwise healthy individuals, but can be problematic in pregnant women. Your sister is expecting her first child, so you call her immediately and tell her about the recall. You fill her in on what you know about this organism and the disease it causes, having just learned about it yourself in your pre-nursing microbiology class. Your sister has questions that you are able to answer.
-Why is listeriosis so important in pregnant women even though it usually causes them few symptoms?

A) Listeriosis suppresses the woman's immune system; she fails to make IgG that would protect her fetus.
B) Listeriosis causes significant signs and symptoms in pregnant women and may prove fatal because they cannot take medication while pregnant.
C) Bacteremia commonly occurs, resulting in infection of the fetus; miscarriage, stillbirth, or infection of the newborn can result.
D) Infants born with listeriosis are sensitized against the foods in which the causative agent is found, such as soft cheeses. They can never eat these foods.
E) Listeriosis in a pregnant woman usually leads to untreatable meningitis. Neither she nor her fetus is able to survive the infection.
