Partitioning the roots of interactions between microbes (PRISM): environment-supplied resources versus species-produced mediators
The PRISM study develops an assay to partition microbial interactions into contributions from environmental resources versus species-produced metabolites, revealing that while *Staphylococcus* metabolites generally suppress other nasal strains, commensal *Corynebacterium* species can facilitate *Staphylococcus* growth, thereby offering a framework to better modulate bacterial communities for therapeutic applications.
