研究目的:

验证罗伊氏乳杆菌PB-W1和其自然突变株P1D42-6在人体消化道内定植能力的差异,为筛选具有人体定植潜力的益生菌菌株提供理论依据。  

Objectives of Study:

To compare the colonization capacity of Lactobacillus reuteri PB-W1 and its natural mutant P1D42-6 in the human gastrointestinal tract, thereby providing theoretical basis for screening effective probiotic strains with persistent colonization potential in human.

Exclusion criteria:

Exclusion criteria are as follows: (1) History of chronic gastrointestinal disorders (e.g., inflammatory bowel disease, celiac disease), diabetes, cardiovascular disease, cancer, or other systemic inflammatory conditions. (2) Long-term use of medications, including laxatives, hypoglycemics, antihypertensives, lipid-lowering agents, or anti-inflammatories. (3) Pregnancy (confirmed by urinalysis at screening), lactation, or postmenopausal status. (4) Defecation frequency of less than once per day. (5) Excessive alcohol consumption (>7 drinks/week), tobacco use, or use of illicit drugs. (6) High levels of vigorous exercise (>5 hours/week). (7) Known allergies or intolerances to any study product components. (8) Adherence to a vegetarian or vegan diet. (9) Antibiotic use within the 3 months preceding the study.
