Association between faecal load of lawsonia intracellularis and pathological findings of proliferative enteropathy in pigs with diarrhoea
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. A total of 156 pigs (10 to 70 days post weaning) with diarrhoea were randomly selected from 20 herds: The pigs were subjected to necropsy, histopathology, immunohistochemistry an...

Materials and methods: On 15 British farms, invertebrate communities were trapcollected (14 per year), counted, and sorted into species groups. Lawsonia serological tests were conducted and total DNA was extracted from pig feces; DNA was also extracted from adult flies, pupae, and larvae samples and viscera of Blatta species. Each DNA sample was tested for L intracellularis by polymerase chain ...

The purpose of this study was to survey Lawsonia intracellularis in dogs in Thailand by using Polymerase chain reaction technique. Lawsonia intracellularis is obligatory intracellular bacterium which causes proliferative enteropathy in animals, including dog. Fecal samples from 48 dogs were collected from Bangkok, Pathumthani and Nakhon Ratchasima and tested for L. intracellularis by PCR techni...
متن کاملEvaluation of the field efficacy of an avirulent live Lawsonia intracellularis vaccine in foals.
Equine proliferative enteropathy caused by Lawsonia intracellularis is an emerging disease with as yet unaddressed preventative measures. The hypothesis of this study was that vaccination will prevent clinical and sub-clinical disease. Weanling Thoroughbreds (n=202) from Central Kentucky were randomly assigned into two groups (vaccinated and non-vaccinated). Vaccinated foals received 30 mL of a...
