目的探讨植物乳杆菌(LP)对炎症性肠病(IBD)小鼠肠道菌群及细菌移位的影响。方法采用白介素10基因敲除(IL-10-/-)小鼠作为IBD动物模型,将8周龄雌性小鼠随机分成空白对照组、IL-10-/-组和IL-10-/-+LP组三组。IL-10-/-+LP组每日灌胃0.5 mL LP菌液(1.0×10~9CFU/mL),其余两组灌胃Ringer缓冲液0.5 mL,持续4周。以小鼠粪便中的双歧杆菌、乳酸杆菌、肠杆菌和产气荚膜梭菌数量及肠系膜淋巴结、脾脏细菌移位为检测指标。结果IL-10-/-小鼠肠内双歧杆菌、乳酸杆菌含量明显下降,肠球菌、产气荚膜梭菌含量升高,且肠道细菌移位明显增加;而连续灌胃LP菌液4周后,益生菌发挥了对肠道的调节作用,纠正了肠道菌群失衡,并降低了肠道细菌移位。结论LP能纠正炎症性肠病小鼠肠道菌群紊乱,减少细菌移位,从而增强了肠道屏障功能。
