alginate slime

alginate slime

A polysaccharide polymer that coats the surface of colonies of the bacterium, Pseudomonas aeruginosa. The slime forms a matrix which anchors bacteria to their environment and protects them from host defenses such as antibodies, complement, lymphocytes, phagocytes, and respiratory cilia. Strains of P. aeruginosa that produce alginate slime (called mucoid strains) are frequently isolated from the lungs of patients with cystic fibrosis.
