Dynamics of phages and bacteria in the gut may play key roles in human health. In this issue of Cell Host & Microbe, De Sordi et al. (2017) provide insights into phage-bacteria interactions, finding that microbial communities contribute to phage persistence in the mammalian gut by supplying new hosts.

作为媒人的哺乳动物内脏

肠道中噬菌体和细菌的动态可能在人类健康中发挥关键作用。在本期《细胞宿主与微生物》中，De Sordi等人。（2017）提供了对噬菌体与细菌相互作用的见解，发现微生物群落通过提供新的宿主促进了哺乳动物肠道中噬菌体的持久性。
