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 disease due to G. discoides is more specifically termed gastrodiscoidiasis. [16] In their natural hosts such as pigs and monkeys, their infection in asymptomatic, but human infection is prevalent, by which they cause serious health problems, characterised by diarrhoea, fever, abdominal pain, colic, and an increased mucous production.
Illnesses transmitted from animals to humans could kill 12 times as many people in 2050 than they did in 2020, researchers have warned.. Epidemics caused by zoonotic diseases – also known as ...
A graph of the cases of brucellosis in humans in the United States from the years 1993–2010 surveyed by the Centers for Disease Control and Prevention through the National Notifiable Diseases Surveillance System [9] The symptoms are like those associated with many other febrile diseases, but with emphasis on muscular pain and night sweats ...
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.
Reports of human disease are limited to immunocompromised and AIDS patients, with only the rabbit and dog strains being potentially dangerous. [6] In eastern Slovakia, the seroprevalence was 5.7%, and in humans with immunodeficiencies, it was as high as 37.5%. [8] In horses, the seroprevalence ranges from 14% to 60%. [9] [10]
Rat-bite fever (RBF) is a zoonotic disease. [10] It can be directly transmitted by rats, gerbils, and mice (the vectors) to humans by either a bite or scratch or it can be passed from rodent to rodent. [11] The causative bacterial agent of RBF has also been observed in squirrels, ferrets, dogs, and pigs. [12]
Similarly, HIV originating in simians (crossover due to humans consuming wild chimpanzee bushmeat) and influenza A viruses originating in avians (crossover due to an antigenic shift) could have initially been considered a zoonotic transference as the infections first came from vertebrate animals, but could currently be regarded as an anthroponosis because of its potential to transfer between ...
