Acute hepatitis in an opossum (Didelphis virginiana) infected with Salmonella turnidorp.

Salmonella turnidorp was isolated in pure culture from the liver of an opossum that died of acute hepatitis. Microscopically, there were random foci of hepatic coagulation necrosis and gram negative bacteria within hepatocytes. The Salmonella turnidorp isolate was aberrant in that it did not utilize citrate and did not agglutinate by a commercial Salmonella polyvalent antiserum. Additional Salmonella serotypes, including Salmonella mbandaka, Salmonella rubislaw, and Salmonella anatum were isolated from three of five healthy opossums caught in Texas.
