Answer Key for Chapter 1. Introduction

• 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:

• Definitive host phase
• Diagnostic stage
• Infective stage
• 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.KEY: Introduction: parasite definitions/life cycles | Cognitive level: recall

2. A parasite that lives inside a host is referred to as a(n):

• Accidental parasite
• Ectoparasite
• Endoparasite
• 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.KEY: Introduction: parasite definitions/life cycles | Cognitive level: recall

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

• Accidental parasite
• Ectoparasite
• Endoparasite
• Facultative parasite

ANS: 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
