The fruit bat is believed to be the zoonotic agent responsible for the spillover of the Ebola virus. Spillover is a common event; in fact, more than two-thirds of human viruses are zoonotic . [ 4 ] [ 5 ] Most spillover events result in self-limited cases with no further human-to-human transmission, as occurs, for example, with rabies, anthrax ...
The thin-shelled and shell-less eggs are so fragile and thus may get eaten by the chickens and get disregarded as litters. The shells may also be rough or chalky. Watery egg whites and a reduction in egg size may also happen as well. [13] [14] The affected chicken flocks show a failure to reach a peak egg production.

[1] [2] Mycoplasma gallisepticum is a significant pathogen in poultry. Mycoplasmosis is the disease caused by infection with mycoplasmas. Mycoplasmas have many defining characteristics.
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.

Both strains can cause HPAI, which can cause these symptoms in humans, per the CDC: eye redness. mild flu-like upper respiratory symptoms. pneumonia requiring hospitalization. fever. cough. sore ...
The theory gained steam on Facebook, TikTok and Twitter in recent weeks, with some users reporting that their hens stopped laying eggs and speculating that common chicken feed products were the cause.
Signs of reproductive disease (Egg Drop Syndrome) include low egg production/hatching and the laying of abnormal eggs (size, shape, colour, texture). Adenovirus infection may infect other organs, causing splenitis , inclusion body hepatitis , bronchitis , pulmonary congestion ventriculitis , pancreatitis , or oedema , depending on the species ...
