Arianne recently traveled abroad where she enjoyed eating food from different countries and learning about different cultures. A week after she returned home, she checked into the hospital with signs of nausea, fever, and diarrhea. What best explains what happened to Arianne?
Answer
A
A parasitic bacteria contaminated her food.
B
A mutualistic bacteria infected her digestive system.
C
A commensalistic organism is now living in her intestine.
D
A predatorial organism is consuming her natural bacteria.
Explanation
Nausea, fever, and diarrhea after traveling are signs of a foodborne infection. A parasite or harmful bacterium in contaminated food can cause these symptoms. Mutualistic and commensal organisms generally live with a host without causing illness, and the choices about predation do not best explain her symptoms.
