Technical Abstract: Weaning is a major change in a pig's life and many of these changes affect the gastrointestinal tract of swine. One of the changes is the types of bacteria that are associated with enteric disease. This review will concentrate on the diagnosis and control of enteritis in weaned pigs caused by Salmonella spp. and Escherichia coli. Diagnosis is typically based upon bacterial culture and frequently includes further characterization of the isolate, such as serology or genetic characterization. The polymerase chain reaction has decreased the time needed for genetic characterization and should be a useful tool for diagnosis in the future. Control of these pathogens is best accomplished using management techniques, in conjunction with vaccines and antibiotics. In the future, we may be able to control these diseases by genetic selection of resistant breeding stock.
