25
Q

Factors Affecting Parasitism*

A

Parasite reproductive capacity
* Number of parasites
* Host immune resistance
* Climate and season
* Cattle management practices

26
Q
  • Eukaryotic, multicellular
    • Cylindrical and tapered
    • Complete digestive system
    • Mostly dioecious (separate sexes)
    • Males smaller with spicules
    • Free-living or parasitic
    • Live in the host for most of their lives
    • Examples: *Ascaris, hookworms,
A

Nematodes (roundworms)

27
Q
  • Flat, leaf-shaped bodies
    • Ventral and oral suckers
    • Absorb food through cuticle
    • Named after host tissue where they reside (e.g., lung fluke, liver fluke)
A

Trematoda (flukes)

28
Q
  • Intestinal parasites
    • Scolex (head) with suckers, sometimes hooks
    • Absorb food through cuticle
    • Body consists of proglottids (segments with reproductive organs)
A

Cestodes (tapeworms)

29
