Salmonella Dublin is unlike other Salmonella’s. It does not cause diarrhea and mostly is responsible for causing pneumonia that is not responsive to antibiotics.

While Salmonella  Dublin can cause diarrhea, it seems that the main signs we are seeing in Western Canada are pneumonia and septicemia. Signs that a producers might be dealing with pneumonia in preweaned calves include dry noses, fever and breathing fast or hard. It is difficult to diagnose Salmonella  Dublin, as manure samples are not effective and only tissue or blood samples can be used. Post-moterm examinations should routinely be performed on each animal that dies or is euthanized to determine which diseases are present in the herd.
