Encephalitic form in a female sheep in a goat. Listeriosis is an infectious but not contagious disease caused by the bacterium Listeria monocytogenes, far more common in domestic animals (domestic mammals and poultry), especially ruminants, than in human beings.
In goats which develop the neurological form of the disease, the onset of signs is gradual over several weeks. The hind legs are most often affected. The goat will be uncoordinated, and unable to place its feet properly, so that it "knuckles", that is, it stands with the front of its fetlock on the ground, rather than its hoof.
Electron micrograph of Bluetongue virus, scale bar = 50 nm. Bluetongue (BT) disease is a noncontagious, arthropod-borne viral disease affecting ruminants, [1] primarily sheep and other domestic or wild ruminants, including cattle, yaks, [2] goats, buffalo, deer, dromedaries, and antelope. [3]
The long-distance spread is by sick animals. [11] As the virus soon becomes inactive outside the body, indirect contamination is generally limited. In an affected flock, even in pest-free regions, the disease does not progress very rapidly, in spite of the close contact between animals. New clinical cases may be observed daily for a 1-month ...
Sheep and goats are both small ruminants with cosmopolitan distributions due to their being kept historically and in modern times as grazers both individually and in herds in return for their production of milk, wool, and meat. [1] As such, the diseases of these animals are of great economic importance to humans.
Ovine pulmonary adenocarcinoma (OPA), also known as ovine pulmonary adenomatosis, or jaagsiekte, is a chronic and contagious disease of the lungs of sheep and goats. OPA is caused by a retrovirus called jaagsiekte sheep retrovirus (JSRV).
Gwendoline Christie breaks down that 'bizarre' and 'terrifying' “Severance” goat reveal (exclusive)
Caprine arthritis encephalitis virus (CAEV) is a retrovirus which infects goats and cross-reacts immunologically with HIV, [1] due to being from the same family of viruses. [medical citation needed] CAEV cannot be transmitted to humans, including through the consumption of milk from an infected goat. [2] There is no evidence that CAEV can cure ...
