Which of the following is a true statement about food-borne infections? a. Hepatits B is frequently food-borne. b. E. coli outbreaks are nearly always caused by tainted ground beef. c. All E. coli are pathogenic. d. Shellfish can be contaminated with Vibrio cholera from their water source.
E. coli can cause various infections and food poisoning.
How can people protect themselves from becoming sick
with E. coli? On the other hand, many bacteria live in our
digestive tract, including E. coli, are important in
producing vitamins and enhancing our absorption of
nutrients. They represent roughly around 3 Ibs of an
adult's body weight, and some scientists call them a
person's second brain. Antibiotics can kill both "good"
and "bad" bacteria. What are some of the effects of
antibiotics killing good bacteria? How does consuming
acidophilus influence your normal intestinal flora? What
are some of the things people do to take care of the
"microbial friends" inside their guts?
Which of the following statements is incorrect?
a. Mucosal surfaces are better than skin surfaces at supporting colonization by commensal microorganisms.
b. The skin provides a larger surface area than mucosal surfaces for commensal microorganisms.
c. There are ten times as many bacteria residing in the intestinal tract than the number of cells in the human body.
d. It is common for commensal bacteria to live in symbiosis with their human hosts.
e. During gestation in mammals, a fetus does not have any commensal microorganisms on their skin or mucosal surfaces.
