Bacterial capsules are highly organized polysaccharide layers that serve as essential protective barriers for many pathogenic microorganisms. By shielding the cell from environmental stress and host immune responses, capsules enable bacteria like Pseudomonas aeruginosa to establish persistent and often drug-resistant infections. Understanding the anatomical complexity of the bacterial envelope is fundamental to developing effective antimicrobial strategies and improving patient outcomes in clinical settings.
