Lawsonia intracellularis infection and proliferative enteropathy in foals [PDF]

Veterinary Microbiology, 2013
Equine proliferative enteropathy (EPE) is a disease of foals caused by the obligate intracellular organism Lawsonia intracellularis. This organism is unique in that it causes proliferation of infected enterocytes, resulting in thickening of the intestinal epithelium, most often the small intestine.

Development and validation of a flow cytometry antibody test for Lawsonia intracellularis [PDF]

Frontiers in Immunology, 2023
Lawsonia intracellularis is the etiologic agent of porcine proliferative enteropathy (PPE), an inflammatory bowel disease with a major economic impact on the pig industry. The serological diagnosis of PPE can be performed using Blocking or Indirect ELISA,

Experimental infection of high health pigs with porcine circovirus type 2 (PCV2) and Lawsonia intracellularis [PDF]

Frontiers in Veterinary Science, 2022
BackgroundPorcine circovirus type 2 (PCV2) and Lawsonia intracellularis infections can cause enteritis in pigs. A Danish study showed a significantly higher probability of detecting PCV2 without concurrent L.

Evaluation of mouse enteroids as a model for Lawsonia intracellularis infection [PDF]

Veterinary Research, 2019
Lawsonia intracellularis, an obligate intracellular bacterium, is an important enteric pathogen in pig herds and horse farms worldwide. The hallmark feature of L. intracellularis infection is the proliferation of epithelial cells in intestinal crypts.
