Physical contacts between sparse biofilms promote plasmid transfer and generate functional novelty

J. Ramoneda, Y. Ma, J. Schmidt, M. Manhart, D. C. Angst, D. R. Johnson

This study shows that biofilm collisions promote plasmid transfer between discrete biofilms, with transfer rates influenced by spatial positioning and plasmid dynamics.

Timing of antibiotic administration determines the spread of plasmid-encoded antibiotic resistance during microbial range expansion

Y. Ma, J. Ramoneda, D. R. Johnson

This study shows that administering antibiotics at intermediate times during microbial expansion minimizes plasmid-encoded antibiotic resistance spread.

Metabolic interactions control the spread of plasmid-encoded functional novelty during microbial range expansion

Y. Ma, A. Kan, D. R. Johnson

This study shows that metabolic interactions influence the spread of plasmid-encoded antibiotic resistance during microbial range expansion by affecting spatial positioning and conjugation rates.

Close-Range Interactions Favor Growth in Random-Paired Extracted Soil Bacteria

M. Dubey, N. Hadadi, S. Pelet, D. R. Johnson, J. R. van der Meer

The paper tests growth interactions between soil bacteria and inoculants in encapsulated pairs, finding that inoculants often boost sand cell growth, but not their own maximum productivity.
