Bovine Salmonellosis

Abstract

The role of Salmonella in feedlot and stocker calf disease complex is probably more significant than is routinely recognized. Some of the recognition problem is that the clinical presentation in older calves is not the same as those observed in younger nursing calves which usually have an acutely fatal severe hemorrhagic diarrhea with septicemia. Additionally, some salmonella infections/isolates may in fact be secondary to a primary disease process but still play a significant role in the outcome of the primary disease. Some salmonella serotypes are of minimal pathogenicity and may have little or no clinical significance even though they are readily isolated.
