Oral | BALB/c female mice and their offspring | Antibiotic group: Receive daily oral penicillin (31 mg/kg) for one week before the birth of offspring. Probiotic group: Same antibiotic treatment with daily L. rhamnosus JB-1 supplement (1×109 CFU/d). Control group: Regular water and food. After birth, analyses the GI phyla of offspring after 6-weeks normal feeding. | Gastrointestinal tract | In antibiotic group, the GI phyla in offspring demonstrated a significant increment of relative abundance of Firmicutes and Lachnospiraceae while a decrement of Bacteroidetes and Prevotellaceae comparing with probiotic group and control group. The results indicated that with probiotic supplement, the prior maternal GI dysbiosis can be restored in their offspring. | Leclercq et al.166 |

The restoration speed is significant faster in probiotic treatment group compared with natural recovery group. | Shi et al.167 |
