They consist of a wide range of diseases and range from endemic zoonoses such as brucellosis, anthrax, bovine tuberculosis, parasitic diseases (hydatid disease, echinococcosis, trichinellosis) and rabies to emerging zoonoses, such as highly pathogenic avian influenza, Nipah/Hendra disease and Bovine Spongiform Encephalopathy.
