Dictyocaulus viviparus found in the bronchi of a calf during necropsy (arrow). 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.
Studies on mycotoxins show that there are three ways to preventing them from contaminating feed. The first occurs before there is a possibility of fungal infection. The second is when the fungi are starting to produce the toxins. And the final way to prevent contamination is when the material is known to be heavily infected. [4]
As indicated above, common ragwort has become a problem in several areas in which it has been introduced, and various methods are employed to help prevent its spread. In many Australian states ragwort has been declared a noxious weed, and landholders are required to remove it from their property by law. [citation needed] In the island state of ...

A CDC infographic on how antibiotic-resistant bacteria have the potential to spread from farm animals. Antibiotic use in livestock is the use of antibiotics for any purpose in the husbandry of livestock, which includes treatment when ill (therapeutic), treatment of a group of animals when at least one is diagnosed with clinical infection (metaphylaxis [1]), and preventative treatment ...
The portal of infection is uncertain, but ingestion of infected feed seems the most usual way. However, inhalation and conjunctival contamination might also play a role. [2] The disease is not contagious. The disease is sporadic, but can occur as farm outbreaks in ruminants.
The disease is spread by various Amblyomma ticks, and has a large economic impact on cattle production in affected areas. There are four documented manifestations of the disease, these are acute, peracute, subacute, and a mild form known as heartwater fever.
The virus sheds in such high titers that it will spread rapidly throughout a herd. Even though cattle might not be showing clinical signs they can still spread the disease. Aside from cattle, studies experimentally infecting animals have shown that goats and buffalo can act as reservoirs for BoHV-1, as well as red deer, sheep, swine, and ...
