Q

Main features of

Cyclophyllidae

(Mesocestoides, Taenia, Echinococcus spp.)

A
  1. Live a adults in carnivorous mammals or humans
  2. Usually do not cause harmful effects in the final host
  3. Usually no symptoms occurs in the intermediate hosts
  4. They live for years in the intermediate hosts but the lifespan is shorter in the final host
