Evidence of host adaptation in Lawsonia intracellularis infections [PDF]

Veterinary Research, 2012
Lawsonia intracellularis is the causative agent of proliferative enteropathy, an endemic disease in pigs and an emerging concern in horses. Enterocyte hyperplasia is a common lesion in every case but there are differences regarding clinical and pathological presentations among affected species.

An Alternative Method for Cultivation of Lawsonia intracellularis [PDF]

Journal of Clinical Microbiology, 2012
ABSTRACT An alternative method for the cultivation of Lawsonia intracellularis , an obligate intracellular bacterium and the causative agent of proliferative enteropathy, was developed using an Original Space Bag inflated with a mixture of gas containing 10% hydrogen, 10% carbon dioxide, and 80% nitrogen ...

Review of methods for the detection of Lawsonia intracellularis infection in pigs. [PDF]

J Vet Diagn Invest, 2021
Lawsonia intracellularis is an obligate intracellular bacterium associated with enteric disease in pigs. Clinical signs include weight loss, diarrhea, and, in some cases, sudden death. The hallmark lesion is the thickening of the intestinal mucosa caused by increased epithelial cell replication, known as proliferative enteropathy.

Lawsonia intracellularis in Wild Mammals in the Slovak Carpathians [PDF]

Journal of Wildlife Diseases, 2003
Feces of wild mammals were collected in the Bukovské Vrchy Hills (north-eastern Slovakia) in January and February 2002. The feces were examined for Lawsonia intracellularis by means of nested polymerase chain reaction. A total of 194 samples of feces from red deer (Cervus elaphus), 46 samples from roe deer (Capreolus capreolus), 31 samples from red fox

Herd diagnosis of low pathogen diarrhoea in growing pigs – a pilot study [PDF]

, 2014
BACKGROUND: The major indication for antibiotic use in Danish pigs is treatment of intestinal diseases post weaning. Clinical decisions on antibiotic batch medication are often based on inspection of diarrhoeic pools on the pen floor.

Association between faecal load of lawsonia intracellularis and pathological findings of proliferative enteropathy in pigs with diarrhoea

BMC Veterinary Research, 2012
Background The study was designed to investigate correlation between histological findings of Lawsonia intracellularis in porcine cases of diarrhoea and the quantitative detection of Lawsonia intracellularis in faeces.

Spread of an Experimental Salmonella Derby Infection in Antibiotic-Treated or Lawsonia intracellularis Vaccinated Piglets

Animals, 2018
Lawsonia intracellularis infections are a common reason for antibiotic treatment in pig production. Experimental studies in animals naturally infected with Lawsonia intracellularis comparing the course of an experimental Salmonella infection in piglets ...

Nutrient digestibility, organ morphometry and performance in vaccinated or non-vaccinated Lawsonia intracellularis infected piglets

BMC Veterinary Research, 2018
Background Lawsonia intracellularis is one of the world’s most important infectious diseases in pork production with regard to economic losses. So far, studies are missing that describe the effects of a natural infection of piglets on the digestibility ...
