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, captured during a swine's necropsy, this photograph depicts the grossly-pathologic appearance of an enlarged hepatogastric lymph node in a pig with an acute case of African swine fever (ASF). Note that this node had been cut, revealing its interior, which was dark red in color due to the hemorrhages contained inside the gland.
African swine fever is caused by an enzootic DNA virus belonging to the family Asfarviridae. “Classic ASF is a highly-contagious, often acute, viral disease of domestic swine characterized by fever, marked cyanosis of the skin areas, and pronounced hemorrhages of the internal organs, particularly the lymph nodes, kidney, and gastrointestinal mucosa, with mortality approaching 100 percent in initial epizootics (in the classic disease).”
