The intestinal microbiota promote myriad functions that affect the host. In this issue of Cell Host & Microbe, Caballero-Flores et al. (2020) demonstrate that resident microbes can thwart gut colonization by the enteric bacterial pathogen Citrobacter rodentium by consuming amino acids, thus starving the invading organism of essential nutrients.

饿死敌人

肠道菌群可促进影响宿主的多种功能。在本期《细胞宿主与微生物》中，Caballero-Flores等人。（2020）证明常驻微生物可以通过消耗氨基酸来阻止肠细菌病原体啮齿动物柠檬酸杆菌的肠道定殖，从而使入侵的有机体饥饿。
