Q

Disadvantages to sexual reproduction

A
  • Longer life cycle
  • Must have at least 2 parasites (Male + Female)
  • Jack Russel pic w/ puppy
17
Q

Disadvantages of Asexual Reproduction

A

-lack of genetic diversity

18
Q

Advantages to Asexual reproduction

A
  • Short life cycle
  • 1 parasite is enough
  • example: walking cat pic

Q

Parasite Fitness:

Benefits from the host-

A

  • Heat
  • Food
20
Q

Parasite Fitness:

Habitat and Food-

A
  • Predilection site

- Aberrant Site

21
Q

Host-parasite Balance

The Parasite

A
  • # of parasites
  • location of the parasites; migration
  • Transmission- forms: transmembrane, transplacental
22
Q

Host-Parasite Balance

The Host response

A
  • previous exposure
  • type of host response (inflammatory, immune, etc)
  • Nutritional status
  • Age of Host
  • relates to previous exposure and size of animal
23
Q

Host-Parasite Balance

Parasite x Host x Environment

A
  • Environmental factors that
    * increase parasites
    * increase hypobiosis
    * decrease immunity
  • Management
  • Geographical location
  • Weather
24
Q

-iasis

A

Presence of parasite

25
Q

-osis

A
