Jacobson, M. 2003. Enteric diseases in pigs from weaning to slaughter. Doctor’s dissertation. ISSN 1401-6257, ISBN 91 576 6387 4 The general aim of this thesis was to study enteric diseases in growing pigs, with special reference to diseases caused by Brachyspira hyodysenteriae and Lawsonia intracellularis. The occurrence of enteric diseases in “growers” is a problem of increasing importance in...

Anaerobic intestinal spirochaetes of the genus Brachyspira include several important pathogenic species, particularly those infecting pigs and chickens. In this study a multiplex-quantitative polymerase chain reaction (M-qPCR) assay was developed based on amplification of a 198 base pair portion of the NADH oxidase gene, using TaqMan probes for detecting and quantifying the three main pathogeni...

BACKGROUND Intestinal disease in nursery pigs is the most common cause of antibiotic usage in pigs in Denmark. The decision to initiate batch medication of intestinal diseases in nursery pigs is typically made by the stock personnel based on clinical assessments of pigs and counting of diarrhoeic faecal pools on the pen floor. The target population of this study was batches of nursery pigs (10-...

Previous studies have reported beta-lactamase-mediated penicillin resistance in Fusobacterium nucleatum, but no beta-lactamase gene has yet been identified in this species. An F. nucleatum subsp. polymorphum strain resistant to penicillin and amoxicillin was isolated from a human periodontitis sample. DNA cloning and sequencing revealed a 765-bp open reading frame encoding a new class D beta-la...
