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 a postmortem, view of a kidney, which had been excised from a domesticated pig ill with a case of hog cholera (HC). The kidney had been sagittally-sectioned revealing its interior, and the petechial hemorrhages seen in the organ’s cortical region.
HC is a highly contagious, acute viral septicemic disease, characterized by generalized hemorrhages. The etiologic agent belongs to the family of viruses known as Flaviviridae. “Because the virus is viable at a pH of 5-10, it is not destroyed by postmortem changes, however, a temperature of 56oC will inactivate it in a few minutes. The pig is the only animal in which HC is known to occur naturally.”
