DETECTION OF Lawsonia intracellularis DNA IN ILEAL TISSUES OF DEAD WILD BIRDS IN THE REPUBLIC OF KOREA

Slovenian Veterinary Research, 2017
Lawsonia intracellularis is an etiological agent that causes proliferative enteropathy in various species. Little is known about the mechanisms of transmission of L. intracellularis, especially in wild bird species. The presence of L.

Expert opinion on the identification, risk assessment, and mitigation of microorganisms and parasites relevant to xenotransplantation products from pigs

Xenotransplantation, Volume 30, Issue 5, September/October 2023., 2023
Abstract Xenotransplantation has the potential to address shortages of organs available for clinical transplantation, but concerns exist regarding potential risks posed by porcine microorganisms and parasites (MP) to the health of human recipients. In this study, a risk‐based framework was developed, and expert opinion was elicited to evaluate porcine ...

Lawsonia intracellularis: INFECÇÃO E PROFILAXIA

Science and Animal Health, 2023
Lawsonia intracellularis é uma bactéria Gram-negativa intracelular obrigatória que causa a Enteropatia Proliferativa Suína (EPS), uma doença economicamente importante para a suinocultura. A infecção é caracterizada pela hiperplasia da mucosa intestinal, desencadeando sinais clínicos como diarreia, perda de peso e, em alguns casos, morte súbita.

Association between average daily gain, faecal dry matter content and concentration of Lawsonia intracellularis in faeces [PDF]

, 2012
Background The objective of this study was to investigate the association between average daily gain and the number of Lawsonia intracellularis bacteria in faeces of growing pigs with different levels of diarrhoea. Methods A longitudinal field study (n =

Within-day repeatability for absolute quantification of Lawsonia intracellularis bacteria in feces from growing pigs [PDF]

, 2012
Absolute quantification of Lawsonia intracellularis by real-time polymerase chain reaction (PCR) is now possible on a routine basis. Poor repeatability of quantification can result in disease status misclassification of individual pigs when a single ...

Enteritis associated with Lawsonia intracellularis and porcine circovirus type 2 infection in wild boars in Southern Brazil Enterite associada com infecção por Lawsonia intracellularis e circovírus suíno tipo 2 em um rebanho de javalis no Sul do Brasil

Ciência Rural, 2008
In a commercial herd of 1250 wild boars, 56 animals were affected by anorexia, diarrhea, and wasting. Enlargement of mesenteric lymph nodes, thickening of ileal wall, and a white-yellowish ileal content were observed in two of the four animals necropsied.
