Lawsonia intracellularis:PHE ileitis outbreak in finishing pigs

摘要

A swine finishing site with two, 1200 head barns (AI/AO by barn, single source) started experiencing a 'bloody diarrhoea' outbreak with two sudden deaths on one day and four the next. This occurred in market weight pigs in Barn 1 one week prior to them being sold. There were no feed antibiotics in the diet and the ileitis vaccine history was unknown to the barn manager.
