Veterinary Epidemiology and Zoonosis

TYPES OF ECOSYSTEM

• Three types of ecosystem can be identified according to their origin.
  • Autochthonous ecosystem 
  • Anthropurgic ecosystem
  • Synanthropic ecosystem 

Autochthonous ecosystem

• Autochthonous ecosystem is one coming from land itself. Example: Tropical rainforest deserts.

Anthropurgic ecosystem

• Anthropurgic ecosystem is one created by man. Example: Cultivated forests and town.

Synanthropic ecosystem

• Synanthropic ecosystem is one that is in contact with man. This facilitates transmission of zoonotic infections. Example: Rats inhabitated in rubbish dumps infected with leptospira may be a source of infection to humans.
