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.

The researchers looked at nearly 12 million virus genomes and detected almost 3,000 instances of viruses jumping from one species to another. Of those, 79% involved a virus going from one animal ...
A zoonosis (/ z oʊ ˈ ɒ n ə s ɪ s, ˌ z oʊ ə ˈ n oʊ s ɪ s / ⓘ; [1] plural 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.
A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. [1] Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. [2] [3] Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity.
Viruses can, and do, turn our world upside down. But they also made us into what we are today.
Pigs are especially important in antigenic shift of influenza viruses. Because pigs can be infected with strains of influenza that infect various other species of animals, they act as 'mixing pots' for the virus. When multiple virus strains, such as a duck and human influenza strain, infect the same pig, antigenic shift is likely to occur.
Avian influenza, or H5N1, is an extremely contagious and deadly respiratory virus for birds. Once infected, the animals rapidly replicate the virus and spread it through airborne particles, feces ...
Viruses are an attractive alternative to chemical pesticides because they are safe to other wildlife and leave no residues. [36] Viruses can also change the behaviour of their insect hosts to their own advantage. A baculovirus of the gypsy moth (Lymantria dispar) makes their caterpillars climb to the tops of trees where they die. In doing so ...
