Immune Response of Pigs Vaccinated Against Proliferative Enteropathy and Co-Infected with Lawsonia intracellularis and Brachyspira hyodysenteriae [PDF]

Animals
Vaccination is a tool to control Lawsonia intracellularis (LI) in pigs. However, pigs may have co-infections that worsen clinical signs and lesions. The aim of this study was to characterize systemic and gut-mediated humoral and cell-mediated immune (CMI)

Manifestation of proliferative enteropathy of pigs (ileitis) in pig farms of Ukraine (diagnostic monitoring)

Біологія тварин, 2021
Proliferative enteropathy of pigs (PPE; ileitis, lawsoniosis) is one of the most common, relatively new and little-studied gastrointestinal diseases of pigs which cause significant economic damage to the pig industry worldwide.

Prevalence and associated risk factors for Lawsonia intracellularis infection in farmed rabbits: A serological and molecular cross-sectional study in South Korea

Frontiers in Veterinary Science, 2023
Lawsonia intracellularis is the etiological agent of proliferative enteropathy, which is globally considered an important enteric disease in pigs and horses. Experimental studies suggest that the organism spreads by subclinical infection of many animals,

Evaluation of the role of clathrin and bacterial viability in the endocytosis of Lawsonia intracellularis

Frontiers in Veterinary Science, 2023
Lawsonia intracellularis is an obligate intracellular bacterium and causative agent of proliferative enteropathy. The pathogenesis of L. intracellularis is not completely understood, including the endocytic mechanisms to access the host cell cytoplasm ...

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).

Pathology of Proliferative Haemorrhagic Enteropathy in Pigs [PDF]

Veterinary Pathology, 1979
Examination of the small intestine of pigs with proliferative haemorrhagic enteropathy showed changes consistent with defects in vascular permeability. Early in the disease there were many eosinophils and distention of lacteals and intercellular spaces with proteinaceous material.

Immunopathogenesis of Experimentally Induced Proliferative Enteropathy in Pigs [PDF]

Veterinary Pathology, 2003
To characterize the immune response associated with Lawsonia intracellularis infection, twenty-eight, 7-week-old pigs were dosed orally with a pure culture of L. intracellularis. Animals were killed 3, 7, 14, 21, 28, 35, and 42 days postinfection. Light microscopic studies were undertaken to immunophenotype the immunologic response using specific ...

Granulomatous enteritis associated with porcine proliferative enteropathy

Brazilian Journal of Veterinary Pathology, 2012
An outbreak of proliferative hemorrhagic enteropathy in a commercial pig farm, characterized by granulomatous enteritis, was studied by slaughter checks and by histopathological, histochemical and immunohistochemical studies.
