Several etiological factors may be involved in enteritises of swine. The pathology may result from the presence of anyone or from a combination of these factors. Of the microorganisms etiologically involved, or at least predisposing, Salmonella choleraesuis is probably most common; however, both viruses and Virio species can predispose. Predisposition due to the added stress accompanying nutritional deficiencies is perhaps more important than any microbial species which has been incriminated, and in many cases of porcine enteric disorders a history of nutritional error exists. Inasmuch as swine enteritises may be either (or both) infectious or non-infectious, therapy should include specific medication and, in addition, instruction in correct management and feeding practices. Undoubtedly the more successful practitioners employ such an armanentarium rather than relying solely upon the so-called "wonder drugs."
