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.

Evidence of host adaptation in Lawsonia intracellularis infections

Veterinary Research, 2012
Background 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 ...

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 =

New Formulation of a Subunit Vaccine Candidate against Lawsonia intracellularis Increases Humoral and Cellular Immune Responses

Vaccines, 2023
Previously, we designed a subunit vaccine candidate based on three L. intracellularis antigens with promising results in pigs. In this study, antigens were produced individually to achieve an even antigen ratio in the formulation.
