Stress often serves as the final precursor to BRD. The diseases that make up BRD can persist in a cattle herd for a long period of time before becoming symptomatic, but immune systems weakened by stress can stop controlling the disease.

Burning the upper layer of soil to eradicate left-over spores is the best way to stop the spread of blackleg from diseased cattle. Diseased cattle should be isolated. Treatment is generally unrewarding due to the rapid progression of the disease, but penicillin is the drug of choice for treatment. Treatment is only effective in the early stages ...
If gas continues to accumulate, the right side of the abdomen may also become distended, with death occurring in cattle within 3–4 hours after symptoms begin. [ 1 ] In free-gas bloat (secondary ruminal tympany), gas builds up in the rumen and cannot escape, due to blockage of the esophagus .

The ultimate factor that causes death is pulmonary edema. In May 2010, a vaccine to protect cattle against East Coast fever reportedly had been approved and registered by the governments of Kenya, Malawi and Tanzania. [12] This consists of cryopreserved sporozoites from crushed ticks, but it is expensive and can cause disease. [citation needed]
Contagious bovine pleuropneumonia (CBPP – also known as lung plague), is a contagious bacterial disease that afflicts the lungs of cattle, buffalo, zebu, and yaks.. It is caused by the bacterium Mycoplasma mycoides, and the symptoms are pneumonia and inflammation of the lung membranes. [1]
In an 1877 testimony to the Cape of Good Hope Commission on Diseases of Sheep and Goats livestock producer J. Webb testified that the appearance of ticks on his farm 8 or 9 years earlier corresponded with an onset of fatal disease in his livestock. Webb reported opening the chest of the victims and discovering the "heart bag" to be full of "water."
