Psittacosis—also known as parrot fever, and ornithosis—is a zoonotic infectious disease in humans caused by a bacterium called Chlamydia psittaci and contracted from infected parrots, such as macaws, cockatiels, and budgerigars, and from pigeons, sparrows, ducks, hens, gulls and many other species of birds.
The disease is caused by the Pigeon pox virus. It can be transmitted by droplet infection from one animal to another, or more commonly through infected insects or the digestion of contaminated food or water. [1] There is a live viral vaccine available for Pigeon pox virus (ATCvet code: QI01ED01 ).
Invertebrates spread bacterial, viral and protozoan pathogens by two main mechanisms. Either via their bite, as in the case of malaria spread by mosquitoes, or via their faeces, as in the case of Chagas' Disease spread by Triatoma bugs or epidemic typhus spread by human body lice. Many invertebrates are responsible for transmitting diseases.

Humans can also be infected through bioterrorism attempts. [15] Francisella tularensis can live both within and outside the cells of the animal it infects, meaning it is a facultative intracellular bacterium. [16] It primarily infects macrophages, a type of white blood cell, and thus is able to evade the immune system.
