Reproduction of porcine proliferative enteropathy with pure cultures of ileal symbiont intracellularis. [PDF]
Infect Immun, 1993 Porcine proliferative enteropathy is consistently associated with the presence of intracellular curved bacteria in epithelial cells in affected portions of intestine. Two strains of these intracellular bacteria were cultured in a cell culture system with rat enterocytes (IEC-18) and passaged several times and used as oral inocula for 14 gnotobiotic and

Comparison of different methods for diagnosis of porcine proliferative enteropathy. [PDF]
Can J Vet Res, 2002 The objectives of this study were: (1) to compare 2 methods of serology; (2) to compare 3 histologic techniques; and (3) to compare 2 methods of detecting shedding in pigs experimentally challenged with Lawsonia intracellularis. The sensitivities of these tests were determined by the detection of infection.

Comparison of 2 serologic tests for the diagnosis of porcine proliferative enteropathy. [PDF]
Can Vet J, 2005 The purpose of this study was to compare results from 2 serological assays at the individual- and herd-level for porcine proliferative enteropathy diagnosis. Cohen's kappa coefficient (k) was used to measure agreement. The tests tend to show better agreement when used at the herd level.
