Bifidobacterium longum |
长双歧杆菌(学名:Bifidobaterium longum)又称龙根菌,是双歧杆菌属的一种厌氧细菌[2][3],属革兰氏阳性菌。此菌可生长在人类消化道中并产生乳酸[4],是婴儿肠道中最早出现的菌种之一[2]。长双歧杆菌绝大多数情况不会致病,常被添加至食品中作为发酵用途[2][5]。
分类
[编辑]2002年,16S 核糖体RNA序列分析的结果显示长双歧杆菌与同属另两种细菌婴儿双歧杆菌(B. infantis)和猪双歧杆菌(B. Suis)的序列相似度高达97%,应属同一物种[6][7]。
生长环境
[编辑]婴儿肠道中有高达九成的细菌为包括本种在内的双歧杆菌属细菌[3],其比例会随婴儿长大成人而逐渐减少,成人的肠道中仅有3%的细菌为双歧杆菌,多种拟杆菌属与真杆菌属的细菌取代该属细菌而成为优势物种[4]。有些长双歧杆菌的菌株对胃酸和胆汁抗性很高,因此能在胃中存活,并进入肠道中[5][8]。
长双歧杆菌具有线毛,可与肠上皮细胞表面的糖蛋白结合,另外其细胞壁上的脂壁酸与带有电荷的多糖也能帮助此菌结合肠上皮细胞[2][9]。
研究
[编辑]免疫系统调节
[编辑]使用长双歧杆菌已被证明可以缩短与普通感冒相关的症状的持续时间并最大程度地减轻其严重程度,其效果与神经氨酸酶抑制剂治疗流感的效果相似。
长双歧杆菌 BB536
[编辑]长双歧杆菌BB536于1969年在健康母乳喂养婴儿的肠道中发现[10]。它经常用于营养补充剂。在一些小型临床试验中,它已被证明可以帮助排便并缓解乳糖不耐症状。[11][12]
