This paper describes how pathogenic invaders interact with a host’s resident community of microbes. The authors infected a nematode host with Staphylococcus aureus bacteria and demonstrated that, over several generations, S. aureus caused imbalance in the nematode’s native microbiome but maintained its capacity to harm the host. These results provide new insight into competition between microbes during infection that can influence disease outcomes and host health.
