Cheaters Lurk In Cooperative Groups
- Within cooperative populations some individuals become cheaters who stop contributing yet still benefit.
- Cheating dynamics influence the stability and outcome of bacterial collective behaviours.
Pseudomonas' Multi-Layered Defences
- Pseudomonas aeruginosa resists threats with strong outer membranes, efflux pumps and biofilm formation.
- Biofilms protect interior cells, use dead cells as resources, and greatly hinder immune and antibiotic action.
