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, taken during a bovine necropsy, this photograph revealed the presence of necrotic lesions involving the animal’s epiglottis, the cartilaginous flap separating the esophagus (food pipe) from the trachea (wind pipe). This cow was suffering from infectious bovine rhinotracheitis (IBR).
IBR, caused by a virus from the family, Herpesviridae, and the genus, Varicellovirus, “is a respiratory disease characterized by inflammation, edema, hemorrhage, and necrosis of the mucous membrane of the respiratory passages, and pustular lesions on the genital organs of both male and female animals.”
