Unit 2 - Parasitism Flashcards
1
Q
What is the definitive host?
A
The host where the parasite reaches sexual maturity.
2
Q
What is the intermediate host?
A
A host that may be required by a parasite to complete its life cycle.
3
Q
What is transmission?
A
The spread of a parasite to a host.
4
Q
What is virulence?
A
The harm caused to a host species by a parasite.
5
Q
How are ectoparasites transmitted?
A
Direct contact or by consumption of intermediate host.
6
Q
How are endoparasites transmitted?
A
By vectors.
7
Q
What are the factors that increase transmission rates?
A
Overcrowding of hosts when they are at high densities.
Mechanisms, such as vectors and waterborne dispersal stages, that allow the parasite to spread even if infected hosts are incapacitated.
