Biofilm Coordination Disclosure Record

PROBLEM: Pseudomonas aeruginosa builds biofilms — surface communities in a self-made extracellular matrix — by combining quorum sensing with surface motility: acyl-homoserine lactone signals synchronize gene expression for polysaccharides, rhamnolipid and virulence factors, while motility shapes the biofilm's architecture. Biofilms behave fundamentally differently from free-floating cells, including marked resistance to standard antimicrobial interventions, and polymicrobial biofilms are hotspots for horizontal gene transfer. Yet facilities that manage water systems, medical devices, or food plants have no standard disclosure record for biofilm coordination: no log of when a surface community switched from planktonic to sessile, what signals drove it, or what resistance it carries.

SOLUTION: A biofilm coordination disclosure record: every monitored surface logged with its biofilm state, the quorum-sensing signals detected, the motility mode observed, and the resistance profile measured — so a biofilm outbreak is disclosed with its coordination history attached, not discovered after the fact.
