Zoonoses can be caused by a range of disease pathogens such as emergent viruses, bacteria, fungi and parasites; of 1,415 pathogens known to infect humans, 61% were zoonotic. [11] Most human diseases originated in non-humans; however, only diseases that routinely involve non-human to human transmission, such as rabies, are considered direct ...
The cause of the epidemic was not determined, but the farm was near a port city known for its pig-smuggling industry and illegal slaughterhouses. Smuggled swine or contaminated meat are thus likely sources of the disease. The disease spread rapidly among swine herds in Taiwan, with 200–300 new farms being infected daily.
Prevention of human brucellosis can be achieved by eradication of the disease in animals by vaccination and other veterinary control methods such as testing herds/flocks and slaughtering animals when infection is present. Currently, no effective vaccine is available for humans.
An investigation of five fur farms in China housing foxes, raccoon dogs and mink found a high risk of diseases developing that could jump from animals to humans, said animal protection group ...
The bird flu virus could pick up from the human virus the ability to infect humans readily, known as reassortment. In other words, the genes are reassorted and trade genetic elements.
Most animals infected with coccidia are asymptomatic, but young or immunocompromised animals may suffer severe symptoms and death. While coccidia can infect a wide variety of animals, including humans, birds, and livestock, they are usually species-specific. One well-known exception is toxoplasmosis caused by Toxoplasma gondii.

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.

While the human medical use of antibiotics is the main source of antibiotic resistant infections in humans, [45] [46] [47] it is known that humans can acquire antibiotic resistance genes from a variety of animal sources, including farm animals, pets and wildlife.
