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] The incubation period is 20 to 123 days.
Bovine respiratory disease (BRD) is the most common and economically devastating infectious disease affecting beef cattle in the world. [1] It is a complex, bacterial or viral infection that causes pneumonia in calves which can be fatal. It also affects many other species of feedlot animals like sheep and pigs, but is most prominent in calves. [2]
Mycoplasma bovis causes a constellation of diseases, including mastitis in dairy cows, arthritis in cows and calves, pneumonia in calves, and various other diseases likely including late-term abortion. Not all infected cows get sick – some shed the disease without becoming ill, allowing for transmission between farms if apparently healthy ...
By 1917, 5% of American cattle were infected with M. bovis (bovine tuberculosis or bTB), including 10% of dairy animals and 1–2% of beef cattle. The rates were going up. The rates were going up. Around 1900, 15,000 Americans, mostly children, died each year from bTB, and many more suffered pain and disfigurement.

Cattle "with signs of Johne’s disease shed billions of bacteria through their manure and serve as a major source of infection for future calves." [ 4 ] Some sources define "paratuberculosis" by the lack of Mycobacterium tuberculosis , rather than the presence of any specific infectious agent, [ 5 ] leaving ambiguous the appropriateness of the ...
