Isolation of Streptococcus pneumoniae biofilm mutants and their characterization during nasopharyngeal colonization.

Abstract excerpt

Asymptomatic colonization of the nasopharynx by Streptococcus pneumoniae precedes pneumococcal disease, yet pneumococcal colonization factors remain poorly understood. Many bacterial infections involve biofilms which protect bacteria from host defenses and antibiotics. To gain insight into the genetics of biofilm formation by S. pneumoniae, we conducted an in vitro screen for biofilm-altered mutants with the...
