"Pseudomonas aeruginosa is an opportunistic pathogen that causes devastating infections in immuno-compromised individuals. Similar to many microbial species, P. aeruginosa can form multicellular communities, termed biofilms. This image was acquired as part of a study investigating the role of extracellular polysaccharides in antibiotic resistance of P. aeruginosa biofilms."
