一项新的研究有助认识在进行粪便菌群移植(fecal microbiota transplant, FMT)后病人肠道微生物组会发生什么。来自德国海德堡欧洲分子生物学实验室(EMBL)的研究人员及其同事们在每名代谢综合征病人接受FMT后对这些病人肠道中的细菌菌株DNA进行测序,发现供者细菌菌株在受者肠道中持续存在高达3个月。研究人员也研究了FMT的供者-受者相容性。相关研究结果发表在2016年4月29日那期Science期刊上,论文标题为“Durable coexistence of donor and recipient strains after fecal microbiota transplantation”。 Durable coexistence of donor and recipient strains after fecal microbiota transplantation Simone S.

To quantify the extent of donor microbiota colonization, we monitored strain populations in fecal samples from a recent FMT study on metabolic syndrome patients using single-nucleotide variants in metagenomes. We found extensive coexistence of donor and recipient strains, persisting 3 months after treatment. Colonization success was greater for conspecific strains than for new species, the latter falling within fluctuation levels observed in healthy individuals over a similar time frame. Furthermore, same-donor recipients displayed varying degrees of microbiota transfer, indicating individual patterns of microbiome resistance and donor-recipient compatibilities. 转化医学:生物谷旗下转化医学专业平台 |
