(A–D) High-throughput qPCR determination of the relative abundance of Actinobacteria, Bifidobacteriaceae, Bifidobacterium, and Bifidobacterium species in responders at day 0 (pretreatment), day 36 (GOS/RP-G28 consumption), and day 66 (GOS/RP-G28 halted, dairy consumption encouraged). (E) High-throughput qPCR determination of the relative abundance of Actinobacteria, Bifidobacteriaceae, Bifidobacterium, and Bifidobacterium species in nonresponders at day 0 (pretreatment), day 36 (GOS/RP-G28 consumption), and day 66 (GOS/RP-G28 halted, dairy consumption encouraged).
