Abstract: The effect of fermented camel milk Gariss and Gariss supplemented with Bifidobacterium lactis (Bb-12) on plasma and liver lipids was determined in rats fed on a cholesterol enriched diet. The two groups decreased the levels of plasma total cholesterol and the Very Low-Density Lipoprotein (VLDL) and Low-Density Lipoprotein (LDL) cholesterol than the positive control group. Gariss containing Bb-12 was more effective in the lowering of plasma and liver cholesterol levels than Gariss without bifidobacterium.
