CHAPTER 1: Introduction to Parasitology
1. Which of the following best defines parasitism?
A) A relationship in which both organisms benefit
B) A relationship in which one organism benefits at the expense of the other
C) A relationship in which neither organism is harmed
D) A relationship in which one organism lives near another without interaction
Answer: B
Parasitism is a relationship in which the parasite benefits at the expense of the host, often causing harm
to the host.
2. A definitive host is defined as the host in which the parasite:
A) Undergoes asexual reproduction only
B) Exists in larval form
C) Undergoes sexual reproduction or reaches adult stage
D) Is accidentally infected
Answer: C
The definitive host is the one in which sexual reproduction occurs or where the parasite reaches its adult
stage.
, 3. An intermediate host is one that:
A) Harbors the adult form of the parasite
B) Is not necessary for the parasite's life cycle
C) Harbors the larval or asexual stages of the parasite
D) Serves as the reservoir host only
Answer: C
The intermediate host harbors the larval or asexual stages of the parasite.
4. Which of the following is an example of a vector?
A) A dog harboring adult tapeworms
B) An Anopheles mosquito transmitting Plasmodium
C) A human accidentally ingesting cysts
D) A snail serving as a reservoir host
Answer: B
A vector is an arthropod that transmits a parasite from one host to another; the Anopheles mosquito
transmits Plasmodium species.
5. The term "zoonosis" refers to:
A) A disease caused by protozoa only
B) A disease transmitted only through contaminated water
C) An infection transmissible between animals and humans
D) A disease found only in tropical regions
Answer: C
