Lopez CA, Skaar EP. Crossed Wires: Interspecies Interference Blocks Pathogen Colonization. Cell host & microbe. 2017 Dec 13;22(22). 721-723.
Abstract
Commensal bacteria protect against invading pathogens using many strategies. In this issue of Cell Host & Microbe, Paharik et al. (2017) find that a commensal blocks Staphylococcus aureus colonization by producing a signal to shut down virulence.
