Abstract

Ileitis in pigs or proliferative enteropathy (PE) is a group of acute and chronic infections in pigs manifested by diarrhea, growth depression and acute mortality due to the proliferation of immature enterocytes and consequent thickening of the mucosa of the distal part of small intestine and proximal part of colon. The causative agent of PE is obligately intracellular Gram - bacterium Lawsonia intracellularis. Clinically, it is manifested in four forms: acute hemorrhagic PE (PHE), chronic PE (porcine intestinal adenomatosis- PIA), regional ileitis and necrotic enteritis. Generally, it occurs in postweaning piglets and in fattening pigs between 6 and 20 weeks of age. Except in pigs, disease may occur in a wide range of host species. Ileitis in pigs has a great economic importance because it causes substantial fi nancial losses in modern pig production.
