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

3. Zoonosis is a term used to describe humans’ relationship with a(n):

b. Ectoparasite
c. Endoparasite
d. Facultative parasite

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
ANS: 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.

2. A parasite that lives inside a host is referred to as a(n):
a. Accidental parasite
b. Ectoparasite
c. Endoparasite
ST
d. Facultative parasite ANS: 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.
