Description Not Available
This study elucidates the immune modulation including the expression of cytokine genes following dietary
administration of three selected probiotic bacteria—Lactobacillus rhamnosus, Enterococcus faecium and Bacillus subtilis
to fish, rainbow trout Oncorhynchus mykiss. They were fed for 45 days on either a basal control diet or one of the three
probiotic diets containing the specific bacteria in freeze-dried form at a density of 109 CFU g feed 1
.
The non-specific immune parameters examined—superoxide anion production by the head kidney leukocytes and the
alternate complement activity of serum was improved by probiotic feeding. Besides this, the relative gene expressions of
interleukin-1b1, tumor necrosis factor 1 and 2 and transforming growth factor-b were up regulated in the spleen and the
head kidney. The comparatively better performance of E. faecium could possibly be linked to their suitable ambient
temperature conditions. Thus, probiotic bacteria delivered in feed exerts its influence on the immune system of fish, both at
cellular and molecular levels.
