Abstract
本发明公开了一种含有人体同源菌株的益生菌粉及其应用,属于微生物技术领域以及医药技术领域。本发明的益生菌粉由两歧双歧杆菌BGN4、长双歧杆菌BORI、乳双歧杆菌AD011、鼠李糖乳杆菌BH09、双重益生元和13种基础营养素组成,能够调节儿童肠道菌群紊乱,具体体现在:这一益生菌粉可改善肠道微生态环境,预防轮状病毒感染,预防及缓解儿童湿疹、过敏性皮肤炎,缓解腹泻、便秘等肠道问题,改善乳糖不耐受,可有效排除食物中的毒素。因此含有两歧双歧杆菌BGN4、长双歧杆菌BORI、乳双歧杆菌AD011和鼠李糖乳杆菌BH09的益生菌粉在调节儿童肠道菌群紊乱上具有很大的应用前景。
Description
技术领域
本发明涉及一种含有人体同源菌株的益生菌粉及其应用,属于微生物技术领域和医药技术领域。
背景技术
儿童早期肠道菌群的建立组成,要追溯到婴幼儿时期在母亲子宫内的肠道菌群建立,经胎盘传递的母亲菌群结构,促使胎儿免疫和肠粘膜发育。
肠道菌群(intestinal microflora)是目前人体微生态学研究者关注的核心问题。随着大家对微生态认识的深入和分子生物学技术的应用广泛,证实肠道菌群对儿童重要的生理功能,诸如免疫、代谢、营养等的发育成熟过程起着决定性的作用,与感染性疾病、肠道慢性炎症性疾病、过敏性疾病、自身免疫性疾病及代谢疾病等密切相关。
肠道正常的微生物菌群可以抑制致病菌的过度生长,对人体健康起屏障作用。国内外对于肠道菌群微生态失衡的问题,临床上主要的方法主要有利巴韦林、潘生丁、蒙脱石散等药物治疗。
发明内容
为了解决婴童时期肠道菌群不平衡的表现特点,如奶瓣、肠胀气、便秘腹泻、过敏、乳糖不耐受等基础肠道不适引起的问题,依据现有临床及研究者发现结果,提出了一种含人体同源菌株的益生菌粉及其应用,具体如下:
