,Answer Key for Chapter 1. Introduction
1. In a general nematode parasite’s life cycle, the host may ingest a fertile egg. This stage
of the life cycle is referred to as the:
a. Definitive host phase
b. Diagnostic stage
c. Infective stage
d. Method of infection
CORRECT ANSWER: C
RATIONALE: This is the stage of the life cycle at which the parasite is capable of entering and
developing within the host. It is a required part of the life cycle of that parasite.
KEY: Introduction: parasite definitions/life cycles | Cognitive level: recall
2. A parasite that lives inside a host is referred to as a(n):
a. Accidental parasite
b. Ectoparasite
c. Endoparasite
d. Facultative
parasite
Leventhal: Medical Parasitology, Ed. 7 Multiple Choice Questions - Chapter 1
, CORRECT ANSWER: C
RATIONALE: Endoparasites live inside the host. Ectoparasites live on the outside of the host.
Facultative parasites can live as well outside the host as inside the host; host infection
usually occurs accidentally. Other accidental parasites may include parasites that usually
infect other animals.
KEY: Introduction: parasite definitions/life cycles | Cognitive level: recall
3. Zoonosis is a term used to describe humans’ relationship with a(n):
a. Accidental parasite
b. Ectoparasite
c. Endoparasite
d. Facultative parasite
CORRECT ANSWER: A
RATIONALE: Zoonosis is an accidental infection with a parasite that usually parasitizes
animals. Endoparasites live inside the host. Ectoparasites live outside the host. Facultative
parasites can live as well outside the host as inside the host; host infection usually occurs
accidentally.
KEY: Introduction: parasite definitions/life cycles | Cognitive level: recall
4. An animal that harbors a parasite that can also infect humans is referred to as a(n):
a. Definitive host
b. Intermediate host
c. Reservoir host
d. Transport host
CORRECT ANSWER: C
RATIONALE: Reservoir hosts harbor parasites that are also infective for humans.
Infections occur when humans encounter infected animals or infective forms related to
that parasite’s life cycle.
