A zoonosis (/ z oʊ ˈ ɒ n ə s ɪ s, ˌ z oʊ ə ˈ n oʊ s ɪ s / ⓘ; [1] pl.: zoonoses) or zoonotic disease is an infectious disease of humans caused by a pathogen (an infectious agent, such as a bacterium, virus, parasite, or prion) that can jump from a non-human vertebrate to a human.
For example, the human body louse transmits the bacterium Rickettsia prowazekii which causes epidemic typhus. Although invertebrate-transmitted diseases pose a particular threat on the continents of Africa, Asia and South America, there is one way of controlling invertebrate-borne diseases, which is by controlling the invertebrate vector.

Cross-species transmission is the most significant cause of disease emergence in humans and other species. [citation needed] Wildlife zoonotic diseases of microbial origin are also the most common group of human emerging diseases, and CST between wildlife and livestock has appreciable economic impacts in agriculture by reducing livestock productivity and imposing export restrictions. [2]
[29] [30] Contemporary diseases of zoonotic origin include SARS, Lyme disease and West Nile virus. [31] Disease emergence and resurgence in populations of wild animals are considered an important topic for conservationists, as these diseases can affect the sustainability of affected populations and the long-term survival of some species. [32]
The disease spread rapidly across the world, and thousands of dogs died from the infection. [13] The virus originated in cats, the vector of feline panleukopenia, but a mutation that changed just two amino acids in the viral capsid protein VP2 [14] allowed it to cross the species barrier, and dogs, unlike cats, had no resistance to the disease ...
Eimeria is another example of an apicomplexan pathogen. This pathogen causes cecal coccidiosis in chickens. Coccidiosis is a parasitic disease of the intestinal tract. [29] This disease is treated by placing anticoccidials in the chickens’ feed. It also causes malabsorption, diarrhea, and sometimes bloody diarrhea in animals.
