Biofilm formation and molecular analysis of intercellular adhesion gene cluster among strains isolated from children with adenoiditis.

Background And Objectives: It is well known that biofilm plays an important role in adenoiditis and biofilm resistance frequently results in failure of therapy. The goal of this study was to evaluate the biofilm production of isolates obtained from adenoid specimens and assess the relationship between biofilm formation ability and operon genes.

Materials And Methods: A total of 112 adenoid samples were obtained from patients under 15 years old with adenoid hypertrophy.
