Prevention of Swine Dysentery with Fitobiotics

چکیده
An effective method was elaborated for extracting the active substances from commercially available Garden thyme and carob seeds. The antibacterial activity of dilutions of thyme and carob extracts and their combinations were studied by taking the minimum inhibitory concentrations (MIC) with agar well diffusion technique. The most effective concentrations of the two herb extracts were used for establishing the best combination of the extracts and on this basis a new feed additive was developed and manufactured for pilot studies. The feed additive efficiently reduced the cost of medications in five pig farms known to be notorious for prevalence of swine dysentery. Feed supplementation also improved weight gain and feed conversion efficiency.

An avirulent Brachyspira hyodysenteriae strain elicits intestinal IgA and slows down spread of swine dysentery
Swine dysentery caused by Brachyspira hyodysenteriae, results in substantial economic losses in swine producing countries worldwide. Although a number of different vaccine approaches have been explored with regard to this disease, they show limitations and none of them have reached the market. We here determine the vaccine potential of a weakly haemolytic B. hyodysenteriae strain. The virulence...
متن کاملSerotype-specific protection against Treponema hyodysenteriae infection in ligated colonic loops of pigs recovered from swine dysentery.
Resistance to Treponema hyodysenteriae (serotypes 1, 2, 3, and 4) infection was evaluated in ligated colonic loops in pigs recovered from swine dysentery. Lesions were present in most loops from recovered swine inoculated with heterologous serotypes; however, lesions were not present in loops of recovered swine inoculated with homologous serotypes.

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 کاملBlood concentrations of the cytokines IL-1beta, IL-6, IL-10, TNF-alpha and IFN-gamma during experimentally induced swine dysentery
BACKGROUND Knowledge of the cytokine response at infection with Brachyspira hyodysenteriae can help understanding disease mechanism involved during swine dysentery. Since this knowledge is still limited the aim of the present study was to induce dysentery experimentally in pigs and to monitor the development of important immunoregulatory cytokines in blood collected at various stages of the dis...
