Effect of Fermented Wheat Germ Extract (fwge) on Shedding Salmonella Infantis and Immunreactions of Broilers
نویسندگان
چکیده
170 broilers have been infected with Salmonella infantis and vaccinated against IBD,(infectious bursal disease) IB, (infectious bronchitis) ND. (Newcastle disease)Feed of 85 broilers has been completed with FWGE (fermented wheat germ extract) Shedding-characteristics of Salmonella infantis and immune reactions after vaccinations were investigated with both broiler groups. Intensity and dynamics of shedding of bacteria by cloacal swabs proved to be equal with both groups and stopped between 1819 day after infection, but cecal content remained positive even on 31-33 days after infection. FWGE increased the IBD VN GMT (virusneutralization geometric mean titers) 7 days after vaccination by 26%, but 21 days after immunization there was no difference in the titres. IB ELISA MMT (mathematical mean titers) 28 and 42 days after vaccination have been increased with the FWGE treated group by 820 and 180% compared to the control. ND HI GMT (haemagglutination inhibition geometric mean titers) proved to be 100% higher with the FWGE treated group on the 42 day of rearing.

Hepatocellular carcinoma (HCC) is one of the most common causes of cancer-related death worldwide. Due to the difficulties of early diagnosis, curative treatments are not available for most patients. Palliative treatments such as chemotherapy are often associated with low response rate, strong adverse effects and limited clinical benefits for patients. The alternative approaches such as ferment...

BACKGROUND Fermented wheat germ extract (FWGE) is a multisubstance composition and, besides others, contains 2-methoxy benzoquinone and 2, 6-dimethoxy benzoquinone which are likely to exert some of its biological effects. FWGE interferes with anaerobic glycolysis, pentose cycle and ribonucleotide reductase. It has significant antiproliferative effects and kills tumor cells by the induction of a...

Anti-inflammatory efficacy of the fermented wheat germ extract (FWGE, Avemar) in the rat adjuvant arthritis (AA) model was examined. To Wistar rats with AA, different doses of FWGE and anti-inflammatory drugs (indomethacin, dexamethasone) as monotherapies were administered and FWGE and either diclofenac or dexamethasone were also given in combination. Besides plethysmographies of the paws, hist...

Model experiment was conducted with growing pigs fed diets containing zero or two levels (1 or 2 g/kg) of fermented wheat germ extract (FWGE). In the first part of the experiment (19 days between 49 and 68 days of age) weight gain and feed conversion were tested. The 2nd part of the experiment (21 days between 68 and 89 days of age) served to measure the effect of FWGE on some compartments of t...

Fermented wheat germ extract (FWGE) is a nutrient supplement and a potential antitumor ingredient for developing an integrated chemotherapy with standard chemotherapeutic drugs for treating ovarian cancer patients. In this study, we evaluated the tumor suppression efficiency of FWGE in human ovarian carcinoma cells, SKOV-3 and ES-2, and found the half-maximal inhibitory concentrations (IC50s) t...
