TLDR
Improvements in understanding of the genetic and molecular basis of bacterial community behavior point to therapeutic targets that may provide a means for the control of biofilm infections.Abstract:
Bacteria that attach to surfaces aggregate in a hydrated polymeric matrix of their own synthesis to form biofilms. Formation of these sessile communities and their inherent resistance to antimicrobial agents are at the root of many persistent and chronic bacterial infections. Studies of biofilms have revealed differentiated, structured groups of cells with community properties. Recent advances in our understanding of the genetic and molecular basis of bacterial community behavior point to therapeutic targets that may provide a means for the control of biofilm infections.read more

Biofilms: Survival Mechanisms of Clinically Relevant Microorganisms
TL;DR: It is understood that biofilms are universal, occurring in aquatic and industrial water systems as well as a large number of environments and medical devices relevant for public health, and that treatments may be based on inhibition of genes involved in cell attachment and biofilm formation.

Antimicrobial peptides: pore formers or metabolic inhibitors in bacteria?
TL;DR: In this review the different models of antimicrobial-peptide-induced pore formation and cell killing are presented and several observations suggest that translocated peptides can alter cytoplasmic membrane septum formation, inhibit cell-wall synthesis, inhibit nucleic-acid synthesis, inhibits protein synthesis or inhibit enzymatic activity.

TL;DR: It is proposed that the size and complexity of the P. aeruginosa genome reflect an evolutionary adaptation permitting it to thrive in diverse environments and resist the effects of a variety of antimicrobial substances.

TL;DR: The involvement of an intercellular signal molecule in the development of Pseudomonas aeruginosa biofilms suggests possible targets to control biofilm growth on catheters, in cystic fibrosis, and in other environments where P. aerug inosaBiofilms are a persistent problem.
