Partnership against Biofilm-associated Expression, Acquisition and Transmission of AMR
The rapid spread of multidrug resistant bacteria threatens the treatment of even simple infections in the near future. However, little is known about how bacteria develop resistance on surfaces.
Aim
The aim of this project was to investigate fundamental mechanisms that shape antimicrobial resistance in biofilms in relation to the surface and then translate those findings into clinical practice.
Method
Researchers developed an integrated model system for reproducibly grow biofilms and studied the underlying mechanisms in biofilms and identified several relevant genes.
Results
The combination of antimicrobials and antibiotics have an important impact on selecting for resistance. The researchers identified novel mechanisms that bacteria use to dynamically adapt to antibiotics when these bacteria grow on surfaces. One such mechanism is associated to the molecular machine that allows bacteria to swim (i.e. the flagellum). These novel antibiotic resistance mechanisms associated to surface growth and the combination effects of antimicrobial surfaces together with systemically applied antibiotics should be taken into consideration when evaluating new antimicrobial surfaces used in healthcare and in medical devices.
