Isolation, Passage, and Pathogenicity of a Newly Isolated <i>Lawsonia intracellularis</i> Strain From Hubei, China. [PDF]

Transbound Emerg Dis
Lawsonia intracellularis is the causative agent of porcine proliferative enteropathy (PPE)—a disease of great economic impact to the global pig industry, but the isolation and continuous passage culture of this bacterial species is very difficult which limits the development of inactivated or live vaccines.

Immunocytological responses in porcine proliferative enteropathies [PDF]

Infection and Immunity, 1992
The ileum, colon, and mesenteric lymph nodes of pigs naturally affected by either of the two major forms of proliferative enteropathy, namely, intestinal adenomatosis or hemorrhagic enteropathy, were examined for immunocytological responses to infection by immunocytochemistry, using antibodies directed against elements of the porcine immune system.

The influence of selected pathological states on the somatostatin-like immunoreactive (SOM-LI) endocrine cells in the mucosal layer of the porcine descending colon

Pesquisa Veterinária Brasileira, 2012
This study reports on changes in the number of somatostatin-like immunoreactive (SOM-LI) endocrine cells in the porcine descending colon, caused by chemically driven inflammation, axotomy and proliferative enteropathy (PE).

Correlation of Lawsonia intracellularis positivity in quantitative PCR and herd factors in European pig herds

Porcine Health Management, 2021
Background Lawsonia intracellularis is causing diarrhea, poor growth and sudden death in pigs. It can be found in most pig populations leading to large economic losses worldwide. Many potential risk factors for the occurrence of disease or seropositivity
