Distinction between Porcine Circovirus Type 2 Enteritis and Porcine Proliferative Enteropathy caused by Lawsonia intracellularis

Journal of Comparative Pathology, 2006
The presence of porcine circovirus type 2 (PCV2) was studied immunohistochemically in formalin-fixed, paraffin wax-embedded samples of intestinal tissue from 80 pigs with a clinical history suggestive of Lawsonia intracellularis-associated diarrhoea. Histopathologically, enteritis of varying intensity was diagnosed in 64 of the pigs.

Serological diagnosis of the porcine proliferative enteropathies: implications for aetiology and epidemiology

Veterinary Record, 1988
Campylobacter mucosalis and C hyointestinalis have been associated with the proliferative enteropathies of pigs. An examination of the antibody response to these organisms and to the intracellular campylobacter-like organism was undertaken. Antibody to the campylobacter-like organism was predominantly IgM, short lived, and could be detected by an ...

Use of tylvalosin‐medicated feed to control porcine proliferative enteropathy

Veterinary Record, 2009
The effect of an oral treatment with the tartrate salt of tylvalosin on the development of proliferative enteropathy in 60 experimentally challenged pigs was studied. Thirty of the pigs were fed a diet medicated with 50 ppm tylvalosin and 30 were fed the unmedicated diet.

Evaluation of the involvement of mice (Mus musculus) in the epidemiology of porcine proliferative enteropathy

Veterinary Microbiology, 2017
The aim of this study was to evaluate the fecal-oral transmission of L. intracellularis between mice and pigs. The study was divided into two parts. The first part aimed to determine whether mice could be infected by feces from pigs that are experimentally infected with L. intracellularis. Thirty-four Swiss mice received L. intracellularis PCR-positive

Developed and resolving lesions in porcine proliferative enteropathy: Possible pathogenetic mechanisms

Journal of Comparative Pathology, 1996
Proliferative enteropathy, caused by Lawsonia intracellularis, offers the opportunity to examine bacterial mechanisms that influence epithelial cell proliferation. Ultrastructural features of developed and resolving lesions included the presence of enlarged intestinal crypts containing undifferentiated immature epithelial cells and an absence of goblet

[Porcine proliferative enteropathy in feeders and breeder sows].

Tierarztliche Praxis. Ausgabe G, Grosstiere/Nutztiere, 1998
Porcine proliferative enteropathy (PPE) was recognized as an important economic factor in pig production. In the following, three cases of PPE in pigs presented for necropsy are discussed. The animals were raised in a stud stock and a weaning production facility in Bavaria.

Current infection patterns of porcine proliferative enteropathy in Great Britain and the Republic of Ireland

Veterinary Record, 2010
PROLIFERATIVE enteropathy (PE) is an endemic bacterial disease of pigs caused by infection with Lawsonia intracellularis ([McOrist and others 1993][1]). The use of targeted intervention programmes against PE is most likely to have a reliable beneficial effect where the time of onset of infection ...

Treatment and prevention of porcine proliferative enteropathy with oral tiamulin.

The Veterinary record, 1997
The effect of an oral treatment or prevention programme, incorporating the antibiotic tiamulin, on the development of proliferative enteropathy in experimentally challenged pigs was studied. Twenty weaner pigs were challenged orally with a virulent inoculum of Lawsonia intracellularis strain LR189/5/83, a British isolate of the causative agent of ...

Lawsonia intracellularisin rodents from pig farms with the occurrence of porcine proliferative enteropathy

Letters in Applied Microbiology, 2008
Lawsonia intracellularis is an obligate intracellular bacterium causing proliferative enteropathy in certain species of domestic, laboratory and captive animals. The aim of our study was to detect L. intracellularis in free-living rodents from pig farms in the Czech Republic.Lawsonia intracellularis was demonstrated, using nested polymerase chain ...
