Question

Quizplus · Accepted Answer

The formation of a biofilm is a common mechanism used by P. aeruginosa to adhere and colonize on lung cells. The signalling molecule secreted by P. aeruginosa recruits other cells to form a biofilm that contributes to persistent infections and antibiotic resistance. A capsule is a thick layer of polysaccharides that surrounds some bacteria for protection, while a slime layer is a thin layer of extracellular polysaccharides that allows bacteria to adhere to surfaces but is easily removed.
