RNA viruses can recombine their genetic material during co-infection. However, the in vivo frequency of co-infections is unclear. In this issue of Cell Host & Microbe, Erickson et al. (2018) demonstrate that an enteric RNA virus concentrates itself through multi-virion binding to bacteria, thus increasing genetic recombination and virus adaptability.

肠病毒在进化高速公路上搭便车

RNA病毒可在合并感染期间重组其遗传物质。但是，并发感染的体内频率尚不清楚。在本期《细胞宿主与微生物》中，Erickson等人。（2018）证明了一种肠道RNA病毒通过与细菌结合的多病毒体来富集自身，从而提高了基因重组和病毒的适应性。
