Summary:To overcome some of the inadequacies of the classic artificial swine dysentery (SD) model that is frequently used to judge the efficacy of drugs in preventing SD, a model has been developed that produces SD comparable with natural infections that are frequently encountered in commercial pig production facilities. The model is a combination of a single oral infection (OI) plus pen contamination (PC), conducted each night for 25 nights. Results with OI alone, PC alone, and OI + PC have been compared, and the new model (OI + PC) produced consistent, homogeneous, and severe SD with 100% morbidity and 92% mortality.
