“Pre-Lab Questions”
1. Escherichia coli is one of the most common causes of food-borne illness, yet
it is also a common microorganism found within the human gut. What
explains this disparity? E. coli illnesses contain certain factors that can be considered
as foreign structures.
These factors cause infection to the host.
2. There are several foods and beverages listed in this lab that are created
through the actions of microorganisms. Name five of the foods and the
specific microorganisms that are used to make each of them.
Cheese: lactococcus, yogurt: lactobacillus, fruit: E. Coli, bread: saccharomyces, milk:
listeria monocytogenes
3. Using an online research tool such as the A-Z index on the CDC website,
explain why Listeria monocytogenes is a major threat to pregnant women
and their developing fetuses, who are ten times more likely to get sick than
other demographic groups. This is a major threat to pregnant women
because this can get through to the placenta, overall harming the fetus. It
can result in serious outcomes such as miscarriage, still birth, and maternal
and neonatal sepsis.
