interleukins IL-6 and IL-10 and tumor necrosis factor (TNF-a), are
some of the several cytokines secreted by intestinal epithelial cells
[18]. The enhanced secretion of antibodies and variations in mucous
layers along the intestine could be crucial in strengthening the
intestinal barrier of GIT [19].
In a previouswork, Ben Salah et al. (2012), have shownthatamong
100 LAB isolated from poultry GIT, several strains exhibit good probiotic
properties. The present study was undertaken to investigate
and evaluate the effects of the supplementation of six selected LAB
strains, TN8 to TN13, with regards to cytokine productions, hepatic
andurinary functions,andbodyweightofWistar rats. Subsequent16S
rRNA gene sequencing identified strainTN8,which exhibited the best
anti-obesity properties, have been done previously by Ben Salah et al.
[20] as a member of Lactobacillus plantarum species.
