The results of a laboratory test show that a type of bacteria called E. coli is living in the digestive tract of an animal. Do the results indicate that the animal is suffering a parasitic infection of E. coli? Cite evidence to support your argument.

E. coli is a bacteria not a parasite. It is not harmful to animals

Explanation:

Escherichia coli (E. coli) bacteria normally live in the intestines of people and animals. Most E. coli are harmless and actually are an important part of a healthy human intestinal tract. However, some E. coli are pathogenic, meaning they can cause illness, either diarrhea or illness outside of the intestinal tract. The types of E. coli that can cause diarrhea can be transmitted through contaminated water or food, or through contact with animals or persons.

it does not cause ill-

ness in animals, but the animals can

serve as carriers of the bacteria. These

bacteria can be found in cattle, sheep,

pigs, deer, dogs and poultry. Infected

animals, especially young ones, can

shed the bacteria in their feces. Cattle

are the main carriers.
