Abstract：
:How gut cells distinguish between beneficial symbionts and deleterious pathobionts is a central question. In this issue of Cell Host & Microbe, Kim et al. (2020) demonstrate that the nucleoside catabolism pathway controlling bacterial uracil and ribose production is an essential trigger of the commensal to pathogen transition.

评论,杂志文章abstract：:The ongoing epidemic of Zika virus (ZIKV) illustrates the importance of flaviviruses as emerging human pathogens. All vector-borne flaviviruses studied thus far have to overcome type I interferon (IFN) to replicate and cause disease in vertebrates. The mechanism(s) by which ZIKV antagonizes IFN signaling is unknown. H...
