[QUOTE="TN Cattle Man, post: 1250667, member: 19746"] Update on the Cow: I just received the final report from Murray State University Breathitt Veterinary Center. A little side-note to this, it was a pleasure talking to CT's own Dr. Lucky Pittman (Lucky_P) during this process in which he kept me very informed. General Results: "An adult cow in acceptable body condition was submitted for necropsy and testing. The animal was moderately autolytic. There was a focal 1 cm abrasion over the right ilium which penetrated the skin. Minimal tissue reaction was associated with this. Lungs were slightly congested while the heart was normal. The liver had multiple, random, variable sized (1-2 cm) round areas of caseous to dry necrosis. These occurred throughout the organ. Kidney's were normal while the gastrointestinal tract had no significant changes." Dx: Necrotizing hepatitis Comments: This is bacterial in origin and would not be considered a herd problem Histopathology: "Lung sections are autolytic. The liver has large areas of infarcted to coagulative necrotic changes. Only shadows of the cells remain in the area. On the periphery of the change sinusoids are expanded by neutrophilis with a few mononuclear inflammatory cells. Where portions of the hepatic parenchyma remain there are still smaller foci of coagulative necrosis. Neutrophils expand the sinusoids. Kidney sections have a few small aggregates of lymphocytes and plasma cells in the interstitial regions of the cortex. Other changes are not noted. Intestines are autolytic." Dx: Severe subacute multifocal necrotizing hepatitis. Comments: Changes in the liver as those seen in this animal generally originate from the intestinal tract. The origin was not found during the postmortem exam. Lack of the ability to culture a pathogen can be due to the age of the lesion or possibly due to growth of the anaerobic bacteria. [/QUOTE]
