Diagnosis and Treatment Methods for Several Common Swine Septicemias

During diagnosis and treatment, affected pigs often show hemorrhagic spots on the skin of the ears, neck, inner sides of the limbs, and underbelly, which are first red, then purple, and later become purpuric patches, along with septicemia and a high fever course. These are often mistaken for swine fever, and treatment is abandoned, causing batch deaths of live pigs and unnecessary losses. However, as long as diagnosis and treatment are done carefully, losses can be reduced. During long-term veterinary outpatient work, the author diagnosed and treated 3005 affected pigs, with a cure rate of 89%. The diagnostic and prevention methods are briefly described below.

1 Swine pasteurellosis

1.1 Symptoms and lesions. Swine pasteurellosis (Pasteurellosis Suum), commonly known as "lock-throat wind," except in the earliest stage of disease, when there are no symptoms and sudden death occurs, later stages follow an acute or chronic course, commonly with septicemic lesions and acute fibrinous pleuropneumonia, elevated body temperature (40-41 degrees C), initially spasmodic dry cough, later becoming a wet cough, difficulty breathing, nasal discharge of mucus or blood, pain on palpation of the chest. Auscultation reveals dry
