  It depends on what kind of parasite you are interested in as there are a lot of different ways that parasites infect. Normally though a successful parasite will:
  – be quite hardy and able to survive in the animal it infects
  – have an easy pathway for the eggs and/or offspring to leave the infected animal
  – be able to find a new host easily
  – enter the host easily without doing too much damage
  – not kill the host so it is able to reproduce inside
