Enteric Viruses Hitch a Ride on the Evolutionary Highway

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.
