Widespread attraction of marine bacteria to the macroalgae-derived polysaccharide fucoidan

Valerio Anelli, Jean‐Baptiste Raina, Riccardo Foffi, Linda Biehler, Richard J. Henshaw, Blake Ushijima, Margot Bligh, Giovanni Stefano Ugolini, Sam Charlton, Milad Radiom, Natasha Blitvic, Raffaele Mezzenga, Andreas Sichert, Johannes M. Keegstra, Roman Stocker

This study shows marine bacteria are attracted to fucoidan at high concentrations, suggesting it guides them to macroalgal surfaces, influencing carbon cycling.

Single-cell approach dissecting agr quorum sensing dynamics in Staphylococcus aureus

Julian Bär, Mariane Pivard, S. G. V. Charlton, Andrew G. Kempchinsky, Alejandro Gómez-Mejía, Giovanni Stefano Ugolini, Srikanth Mairpady Shambat, Eleonora Secchi, Annelies Sophie Zinkernagel

The paper uses single-cell techniques to study agr quorum sensing dynamics in Staphylococcus aureus, revealing differences in AIP sensitivity and community interaction patterns across agr-types.

Bacteria induce an amoeboid phase in coccolithophores that persists after bloom collapse

Sophie T Zweifel, Richard J. Henshaw, Oliver Müller, Johannes M. Keegstra, Sam Charlton, Roberto Pioli, Clara Martínez‐Pérez, Uria Alcolombri, Estelle E. Clerc, Roman Stocker

The paper identifies an amoeboid phase in coccolithophores triggered by bacteria, which persists after bloom collapse and may provide bacterial resistance.
