Biofilms provide pathogens with an adhesion mechanism and aid in resistance to antimicrobial agents.

Question

Quizplus · Accepted Answer

Biofilms are complex structures formed by communities of microorganisms, usually in surfaces at moist environments, and provide a physical scaffolding for bacteria to adhere to surfaces and host tissues. The biofilm secreted exopolysaccharides and extracellular proteins that protect pathogenic microbes from the immune system and antimicrobial agents, facilitating growth and spreading of infections. Therefore, biofilms are associated with chronic and recurrent infections that are hard to treat with conventional therapies.
