摘　　要：双歧杆菌是婴儿肠道中最丰富的微生物,对婴儿肠道微生物的成熟和稳定有显著影响,与婴儿健康紧密相关。大量研究表明,婴儿肠道中最广泛存在的双歧杆菌有长双歧杆菌、短双歧杆菌和两歧双歧杆菌。母婴之间垂直传递可直接影响婴儿肠道中双歧杆菌各种属的早期定植和相对丰度变化,特别是分娩方式和喂养方式会显著影响婴儿肠道双歧杆菌。此外,胎龄和辅食等因素对婴儿肠道中双歧杆菌的组成与多样性也有一定影响。本文对婴儿肠道双歧杆菌的种属组成、相对丰度变化以及影响其多样性的因素进行了综述,为婴儿双歧杆菌群落的认识提供一定的理论依据。Bifidobacteria is the most abundant microorganism in infant gut,which has significant influence on the maturity and stability of infant gut microflora and correlation with infant health.A number of researches showed that Bifidobacterium longum,B.breve and B.bifidum are the most abundant in bifidobacterial community in infant gut.Maternal-infant vertical transmission can influence the early colonization and abundance of different bifidobacteria species directly.Delivery mode and feeding methods as well as gestational age and supplement foods are the major factors affecting the composition and diversity of bifidobacteria community in infants.The current review summarized the species composition and quantity variance of bifidobacteria community in infant gut as well as related affecting factors,which will provide certain theoretical basis for the knowledge of infant gut microbiota.
