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 depicts the rump of a female bovine displaying signs of the vaginal form of infectious bovine rhinotracheitis (IBR). Note the congestion and pustules scattered atop the vaginal mucosa.
“In the respiratory form, the gross IBR lesions are restricted to the muzzle, nasal cavities, pharynx, larynx, trachea, and bronchi. There may be pulmonary emphysema or secondary bronchopneumonia, but for the most part the lungs are normal. In the upper respiratory tract, swelling and congestion of the mucosa, petechia, and catarrhal exudates are seen. Some necrotic foci may be seen on the nasal mucosa. The aborted fetuses show focal necrotic hepatitis, and hemorrhages and autolysis in the kidney. The IBR virus also produces pustular vulvovaginitis and balanoposthitis, but the respiratory and genital forms of IBR are rarely found in the same herd at the same time.”
