Total serum cholesterol was not decreased by Lactobacillus reuteri administration. Total serum cholesterol from a submental blood draw after a 5-h fast was averaged at 0, 2, and 4 wk from wild-type (A) and low-density lipoprotein receptor knockout (LDLr KO, B) mice administered daily by gavage saline [open circles, n = 5 (A and B)], L. reuteri at 1 × 109 colony-forming units (CFU)/day [closed circles, n = 6 (A) and 4 (B)], or L. reuteri at 50 × 106 CFU/day [closed squares, n = 5 (A) and 6 (B)]. Data are presented as means ± SE.
