  • zoon = animal (Gr.)
  • noson = disease (Gr.)

definition

  • disease of vertebral animals that can be transmitted to human, either directly or indirectly through an insect vector
    • dengue is not zoonosis
  • 73% of human-affecting 1,415 pathogens are zoonotic
  • exclusions
    • fish and reptile toxins
    • allergies to vertebrates
    • animal-derived food-borne
      • eg. hep A
  • zooanthroponosis = non-human to human
  • anthropozoonosis = human to non-human
  • amphixenosis = both direction between human and non-human


  • orthozoonosis = perpetuated in nature by a single vertebrate species
    • rabies (skunk in natural host), brucellosis, anthrax
  • cyclozoonosis = requires more than one vertebrate species
    • cestoda (tapeworm)
  • metazoonosis = requires both of vertebrates and invertebrates
    • all arboviral pathogens, some bateria (plague, rickettsia), some parasite (leischmania)
