摘要
The current study investigates whether probiotic fermented milk (PFM) and yogurt consumption (YC) are related to both the ingested bacteria taxa and the overall gut microbiota (GM) composition in healthy adults. PFM and YC habits were analyzed in 260 subjects (51% male) by specific questionnaires, and the following groups were considered: (1) PFM groups: nonconsumers (PFM-NC, n = 175) and consumers (PFM, n = 85), divided as follows: Bifidobacterium-containing PFM (Bif-PFM; n = 33), Lactobacillus-containing PFM (Lb-PFM; n = 14), and mixed Bifidobacterium and Lactobacillus-containing PFM (Mixed-PFM; n = 38); (2) PFM-NC were classified as: yogurt nonconsumers (Y-NC; n = 40) and yogurt consumers (n = 135). GM was analyzed through 16S rRNA sequencing. PFM consumers showed higher Bifidobacteria taxa levels compared to NC, from phylum through to species. Specifically, Bif-PFM consumption was related to higher B. animalis levels (p < 0.001), whereas Lb-PFM consumption was associated to higher levels of Bifidobacterium (p < 0.045) and B. longum (p = 0.011). YC was related to higher levels of the yogurt starter Streptococcus thermophilus (p < 0.001). Lactobacilli and the overall GM were not related either to YC or PFM consumption. According to these results, healthy adults might benefit from PFM intake by increasing Bifidobacterium levels.

目前的研究调查是否益生菌发酵乳（PFM）和酸奶消费（YC）都与摄入的细菌类群，并在健康成人的总体肠道菌群（GM）组成两者。 PFM和YC习惯在260名受试者（51％男性）由特定的问卷进行了分析，并且下列基团被认为是：（1）PFM基团：非消费者（PFM-NC中，n = 175）和客户（PFM中，n = 85） ，如下：含双歧杆菌PFM（BIF-PFM; n = 33），含乳杆菌的PFM（LB-PFM; n = 14），并混合双歧杆菌和含乳杆菌的PFM（混合PFM; n = 38）; （2）PFM-NC被归类为：酸奶非典型（Y-NC; n = 40）和酸奶消费者（n = 135）。通过16S RRNA测序分析GM。 PFM消费者与NC相比，与NC相比，PFIDobacteria Catha级别从门口到物种。具体地，双歧杆菌-PFM消耗，较高有关动物双歧杆菌水平（p <0.001），而LB-PFM消耗相关联的更高水平的双歧杆菌（P <0.045）和长双歧杆菌（p值= 0.011）。 YC与酸奶入学器链球菌嗜热药物的较高水平有关（P <0.001）。乳酸杆菌和整体GM与YC或PFM消费无关。根据这些结果，通过增加双歧杆菌水平，健康的成年人可能会受益于PFM摄入量。
