Parasitic bronchitis, also known as hoose, husk, or verminous bronchitis, [1] is a disease of sheep, cattle, goats, [2] and swine caused by the presence of various species of parasite, commonly known as lungworms, [3] in the bronchial tubes or in the lungs. It is marked by cough, dyspnea, anorexia and constipation.
Bridge scour is the removal of sediment such as sand and gravel from around bridge abutments or piers. Hydrodynamic scour, caused by fast flowing water, can carve out scour holes, compromising the integrity of a structure. [1] In the United States, bridge scour is one of the three main causes of bridge failure (the
The tongue is swollen, cyanotic, and protruding from the mouth. In sheep, BTV causes an acute disease with high morbidity and mortality. BTV also infects goats, cattle, and other domestic animals, as well as wild ruminants (for example, blesbuck, white-tailed deer, elk, and pronghorn antelope).
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.
Transmission is vertical or horizontal by nose to nose contact. The main source of infection is persistently infected animals. While border disease is caused by border disease virus, in areas of the world where close contact between sheep and goats and cattle occurs, similar clinical signs may be caused in sheep and goats by bovine viral diarrhea virus (BVDV).

Sheep and goats: Anaplasma ovis – found worldwide. [13] There is a prevalence of 82.9% in sheep, and 74.9% in goats. This species is the most prevalent for causing anaplasmosis in sheep and goats, although Anaplasma phagocytophilium can also cause the disease. Anaplasma phagocytophilium has a prevalence of 11.9% in sheep, and 15.2% in goats. [14]
Gout causes painful swelling, typically only impacting one joint. Its symptoms can come and go. Periods when gout symptoms are more severe are called gout flares or gout attacks.
The clinical signs are similar in other ruminants. In sheep and goats, the wool or hair is often damaged and easily shed, and diarrhea is uncommon. In deer, paratuberculosis can progress rapidly. Intestinal disease has also been reported in rabbits and nonhuman primates. [citation needed]
