Description:From the “Illustrated Manual for the Recognition and Diagnosis of Certain Animal Diseases”, published in 1982, by the Mexico-United States Commission for the Prevention of Foot and Mouth Disease, this photograph taken at a bovine necropsy, depicts a joint in which excessive synovial fluid, as well as bits of fibrin had accumulated, in the case of a contagious bovine pleuropneumonia (CBPP) infection.
A bacterial infection, CBPP “is a specific disease of cattle, caused by Mycoplasma mycoides subsp. mycoides. It is highly infectious, and occurs in acute, subacute, and chronic septicemic forms. It’s incubation period is up to from 3-6 months, though in more susceptible cattle, incubation may be as short as 10-14 days. Initial signs are fever, cessation of rumination, and severe cough after exercise. Other signs are an arched back, chest pain, distended elbows, and extended head and neck. Grunting expiration, shallow rapid breathing with fluid sounds, followed by gurgling rales, pleuritic friction, and areas of dullness on percussion follow.”
