Bacteria use spatial sensing to direct chemotaxis on surfaces

J. H. R. Wheeler, K. R. Foster, W. M. Durham

This study shows that Pseudomonas aeruginosa uses spatial sensing, not temporal sensing, to detect chemical gradients during surface-based chemotaxis.

Cell motility greatly empowers bacterial contact weapons

S. C. Booth, O. J. Meacock, K. R. Foster

The paper shows that bacterial motility enhances contact-based toxin delivery by increasing inter-strain contact and target switching, improving CDI effectiveness up to 10,000-fold.

Community ecology of phages on a clonal bacterial host

N. C. Pyenson, A. Leeks, O. Nweke, J. Goldford, P. Turner, K. R. Foster, A. Sanchez

The paper shows diverse phage communities stably coexist on a clonal bacterial host due to host phenotypic heterogeneity.

Bows and swords: why bacteria carry short and long-range weapons

S. C. Booth, W. P. J. Smith, K. R. Foster

The paper develops an agent-based model to compare short-range and long-range bacterial weapon systems, showing they function differently based on population dynamics and test predictions using Pseudomonas aeruginosa.

Collective protection against the type VI secretion system in bacteria

E. T. Granato, W. P. J. Smith, K. R. Foster

The paper shows how EPS-producing bacteria collectively defend against T6SS attacks through EPS sharing and flank protection.

Reconfigurable microfluidic circuits for isolating and retrieving cells of interest

C. Deroy, J. H. R. Wheeler, A. N. Rumianek, P. R. Cook, W. M. Durham, K. R. Foster, E. J. Walsh

This paper introduces a microfluidic method to isolate and retrieve cells of interest by using fluid walls to access specific phenotypes in real-time.

Suicidal chemotaxis in bacteria

N. M. Oliveira, J. H. R. Wheeler, C. Deroy, S. C. Booth, E. J. Walsh, W. M. Durham, K. R. Foster

This study shows that Pseudomonas aeruginosa moves towards higher antibiotic concentrations, leading to a suicidal release of bacteriocins to kill competitors.

Droplet printing reveals the importance of micron-scale structure for bacterial ecology

R. Krishna Kumar, T. Meiller-Legrand, A. Alcinesio, D. Gonzalez, D. A. I. Mavridou, O. J. Meacock, W. P. J. Smith, L. Zhou, W. Kim, G. S. Pulcu, H. Bayley, K. R. Foster

The paper develops a droplet printing method to study bacterial ecology by manipulating spatial arrangements of E. coli strains and shows how micron-scale structure affects competition and coexistence.

The Evolution of Mass Cell Suicide in Bacterial Warfare

E. T. Granato, K. R. Foster

The paper develops a fluorescence assay to quantify programmed cell suicide in E. coli during bacterial warfare, finding that under certain conditions nearly all cells lyse to release toxins, which is evolutionarily advantageous as cells are already doomed by toxin exposure.
