The aim of this study was to find suitable and reliable tools for demonstrating Lawsonia intracellularis in routine clinical diagnosis. Firstly, a method to prepare tissue samples before a polymerase chain reaction (PCR) was evaluated in pigs submitted for necropsy. Secondly, seven different faecal preparation methods and four different DNA polymerases were(More)
PURPOSE To develop a pig model that would enable repeated biopsy specimen collection and endoscopic monitoring of the gut. This would increase precision of the experiment and reduce the number of experimental animals required. METHODS Six 10-week-old Yorkshire pigs underwent surgery, and a cannula was inserted in the cecum. Two pigs served as non-operated(More)
PURPOSE Abdominal oedema is common in sepsis. A technique for the study of such oedema may guide in the fluid regime of these patients.

Two different markers were used: red blood cells (RBC)(More)
To investigate the current status of forensic veterinary pathology, a survey was composed directed at pathology laboratories and institutes, mostly in Europe. The questions included number of and type of cases, resources available, level of special training of the investigating pathologists and the general view on the current status and future of the(More)
We compared two strains of avian influenza A viruses of subtype H10 by exposing mink to aerosols of A/mink/Sweden/3 900/84 (H10N4) naturally pathogenic for mink, or A/chicken/Germany/N/49, (H10N7). Lesions in the respiratory tract during the first week after infection were studied and described. Both virus strains caused inflammatory reactions in the lungs(More)
