Post weaning multi systemic wasting syndrome (PMWS) has been described as a "new and unique disease of swine." PMWS is characterized as a disease of 5 to 12 week old pigs. The disease causes wasting and dyspnea with affected pigs also presenting with lymph node enlargement and icterus. The disease first appeared in 1991, in Saskatchewan, Canada. In 1994, the disease reoccurred in Saskatchewan and Alberta. Since then, PMWS has been diagnosed in other provinces of Canada, and the states ofIowa, Illinois, Indiana and California. France and Spain have also reported a similar disease presentation
