Pigs experimentally infected with Serpulina hyodysenteriae can be protected from developing swine dysentery by feeding them a highly digestible diet.

چکیده
Weaner pigs (n = 72) were fed 1 of 4 diets. These were based on either cooked rice and animal protein, cooked rice and lupin, wheat and lupin, or wheat and animal protein. Twenty-six of the pigs were slaughtered after 1 month. Those fed the highly digestible cooked rice and animal protein diet had drier colonic contents and faeces, lighter large intestines, and the contents of their large intestines had increased pH values and decreased total VFA concentrations. The other 46 were orally challenged with broth cultures of Serpulina hyodysenteriae, and were monitored for faecal excretion of the spirochaetes, and for the development of swine dysentery (SD). None of 18 pigs fed the cooked rice and animal protein diet developed colonic changes or disease, whereas most pigs on the other diets developed mucohaemorrhagic colitis and dysentery. The reduced fermentation that occurred in the large intestines of pigs fed cooked rice and animal protein was associated with a subsequent failure of colonization by S. hyodysenteriae, and resultant protection against SD.

Diets containing inulin but not lupins help to prevent swine dysentery in experimentally challenged pigs.
Swine dysentery is a contagious mucohemorrhagic diarrheal disease caused by the intestinal spirochete Brachyspira hyodysenteriae that colonizes and induces inflammation of the cecum and colon. It has been reported that a diet containing chicory root and sweet lupin can prevent swine dysentery. This experiment was conducted to test the hypothesis that inulin in the chicory root rather than galac...
متن کاملThe effect of fermentable carbohydrates on experimental swine dysentery and whip worm infections in pigs.
An experiment was conducted to study the effect of diets with contrasting fermentability in the large intestine on experimental infections with Brachyspira hyodysenteriae, the causative agent of swine dysentery, and the whip worm, Trichuris suis, in pigs. Two diets with organically grown ingredients were composed. Both diets were based on triticale and barley and supplemented with either rape s...
متن کاملCharacterization of two DNA probes specific for Serpulina hyodysenteriae.
Two DNA probes, one 1.1- and one 0.75-kb probe, specific for Serpulina hyodysenteriae were isolated from a genomic library generated from virulent S. hyodysenteriae 5380. These probes are highly specific and react with all S. hyodysenteriae strains tested. Under stringent conditions, the DNA probes did not react with the nonpathogenic species Serpulina innocens or with other species of enteric ...
متن کاملBrachyspira hyodysenteriae binding to porcine colonic mucins differs between individuals 1 and is increased to mucins from infected pigs with de novo MUC 5 AC synthesis
25 Brachyspira hyodysenteriae colonizes the pig colon resulting in mucohemorrhagic diarrhea and 26 growth retardation. Fecal mucus is a characteristic feature of swine dysentery; therefore we 27 investigated how the mucin environment changes in the colon during infection with B. 28 hyodysenteriae, and how these changes affect this bacterium's interaction with mucins. We 29 isolated and characte...
متن کاملInvestigation of the Impact of Increased Dietary Insoluble Fiber through the Feeding of Distillers Dried Grains with Solubles (DDGS) on the Incidence and Severity of Brachyspira-Associated Colitis in Pigs
Diet has been implicated as a major factor impacting clinical disease expression of swine dysentery and Brachyspira hyodysenteriae colonization. However, the impact of diet on novel pathogenic strongly beta-hemolytic Brachyspira spp. including "B. hampsonii" has yet to be investigated. In recent years, distillers dried grains with solubles (DDGS), a source of insoluble dietary fiber, has been i...
