Abstract
The objective of this study wasto investigate in vivo scientific validation of seven wild selected potentially probiotic lactic acid bacteria (LAB) strains isolated from human breast milk, Zabady and Laben Rayb. These strains were used in cultured fermented milk as a vehicle for delivery of beneficial bacteria for five weeks to seven Albino rats groups. Feeding cultured milk products increased rats’ body weight compared to control without significant change in body organs’ weights. Hematology parameters of treated rats were comparable to control. All tested probiotic strains showed a hypolipidemic effect either by reducing triglycerides (TG) or by reducing LDL-Ch and atherogenic indices. There was no remarkable effect on oxidative stress in treated rats according to superoxide dismutase (SOD) and thiobarbituric acid reactive substances (TBARS) determining results and histological examination. The rats’ groups fed cultured milk fermented using mothers’ breast milk originated Enterococcus spp. cultures resulted in higher intestinal and fecal LAB comparing to control group. There was considerable suppression in intestinal and fecal contents of Staphylococcus spp. and coliforms among all treated rats’ groups. Safety considerations of these probiotic strains were confirmed when carcinoembryonic antigen (CEA) levels and histological examination of liver tissues showed no changes comparing to control.
