23
Q

Definitive / Final host

A
  • sexually multiplies
  • releases infectious forms
24
Q

Intermediate host

A
  • may multiply asexually
  • undergoes developmental stage
25
Q

Reservoir host

A
  • parasite lives and multiplies without harming the host
26
Q

Paratenic / Dormant host

A
  • Parasite does not develop further
  • remains alive and infects another host
