Non-canonical stringent response signaling mediates antimicrobial fatty acid sensitivity in Staphylococcus aureus

Caitlin H. Kowalski, Sylvia B Khalil, Dante A James, T. Jarrod Smith, Killian D. Campbell, Rebecca M. Corrigan, Matthew F. Barber

This study shows that truncating the Rel protein in S. aureus enhances tolerance to antimicrobial fatty acids by altering cell envelope structure through the SigB-SarA pathway.

Assembly of skin microbiomes is more neutral than gut microbiomes in multiple animal species

Killian D. Campbell, Brendan J. M. Bohannan, Karen L. Adair

The paper compares neutral and selective processes in shaping skin and gut microbiomes across species, finding skin microbiomes are more influenced by neutral processes.
