b. Diagnostic stage
c. Infective stage
d. MethodJof infection
2. A parasite that lives inside a host is referred to as a(n):
a. Accidental parasite
b. Ectoparasite
c. Endoparasite
d. Facultative parasite

a. Accidental parasite
b. Ectoparasite
c. Endoparasite
d. Facultative parasite
4. An animal that harbors a parasite that can also infect humans isJreferred to as a(n):
a. Definitive host
b. Intermediate host
c. Reservoir host
d. Transport host

stage of the life cycle is referred to as the:
a. Definitive host phase
b. Diagnostic stage
c. Infective stage
d. Method of infection
ANSWER: C
RATIONALE: This is theJstage of the life cycle at which theJparasite isJcapable of
entering and develo pingJwithin theJhost. It is a required part of the life cycleJof 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
ANSWER: C
RATIONALE: Endoparasites live inside the host. Ectoparasites liveJon the outside of
the host. Facult ativeJparasites can live as well outside the host asJinside the host; host
infection usually occurs accide ntally. Other accidental parasites may include
parasites that usually infect other animals.

a. Accidental parasite
b. Ectoparasite
c. Endoparasite
d. Facultative parasite
ANSWER: A
RATIONALE: Zoonosis is an accidental infectionJwith a parasiteJthat usually
parasitizes animals. Endoparasites live inside the host. Ectoparasites live outside
