Chemicals + microbial genes

Check out our new open access paper describing relationships between widespread antimicrobial chemicals and the urban microbial communities that surround us. Although we cannot draw causal links, we find pretty convincing evidence that high evironmental concentrations of the chemical triclosan coincide with lots more Gram-positive bacteria that are enriched for genes involving cellular efflux, stress response, all kinds of different cross-membrane transporters, and resistances to multiple clinically-relevant antibiotic drugs (yikes!). The full set of metagenomic and mass spec data have been made available on the Sequence Read Archive (SRA) under accession no. PRJNA489265.
