a disease of horses, cattle, swine, goats, and young dogs that is characterized by extensive edema of the subcutaneous tissues and hemorrhage in the mucosa, muscles, and internal organs. Petechial fever arises as a complication of such infectious diseases as contagious pleuro-pneumonia, pharyngitis, strangles, and mastitis. The predisposing conditions are upper-respiratory-tract infections, overfatigue, renal or cardiovascular insufficiency, and various avitaminoses. It is believed that the disease results from an allergic reaction that occurs in response to bacterial intoxication. In severe cases, cutaneous and mucous ulcers and necroses arise in addition to edema. Extreme swelling affects the head and extremities. Diagnosis is made on the basis of clinical symptoms. Treatment may include the use of intravenous solutions of various preparations, including Congo red, Formalin, and sodium chloride. Antibacterial therapy is also carried out.
