小鼠微生物组：实验变异性被忽视的罪魁祸首。

Recent studies have found differences between almost genetically identical mice that were attributable to differences between their microbiomes. One example of mice from different vendors having different susceptibilities to infection by Salmonella enterica serovar Typhimurium has just been published in Nature Microbiology.

最近的研究发现，即使遗传基因几乎完全相同的老鼠之间也存在差异，而这些差异归因于它们的微生物组之间的差异。最近在《自然-微生物学》上发表的一篇论文就介绍了来自不同供应商的老鼠对感染沙门氏菌血清型 Typhimurium 的易感性存在差异的例子。
