Pseudomonas aeruginosa, mucoidy and the chronic infection phenotype in cystic fibrosis

Trends Microbiol. 1995 Sep;3(9):351-6. doi: 10.1016/s0966-842x(00)88974-x.

Abstract

During chronic infections in cystic fibrosis, persistence of Pseudomonas aeruginosa is associated with conversion into forms that are associated with conversion into forms that are characterized by a mucoid colony morphology, rough lipopolysaccharide and, paradoxically, decreased systemic virulence. The mutations underlying these changes occur in global regulators, such as alternative sigma factors and their accessory elements.
