Bacteriophage activities against planktonic bacteria and against bacteria embedded in biofilm. A. Replicative bacteria in a planktonic state. B. Adhesion of an active phage at the bacterial surface followed by intrabacterial viral multiplication leading to bacterial lysis and propagation of the infection in the bacterial community. C. Bacteria embedded in biofilm at the surface of an implant. D. Destructuration of the biofilm thanks to the activity of phages and thanks to the activity of phage lysins.
