Characterization of aid1, a novel gene involved in Fusobacterium nucleatum interspecies interactions.

ABSTRACT: The oral opportunistic pathogen Fusobacterium nucleatum is known to interact with a large number of different bacterial species residing in the oral cavity. It adheres to a variety of Gram-positive bacteria, including oral streptococci via the arginine-inhibitable adhesin RadD. In this study, we describe a novel protein encoded by the predicted open reading frame FN1253 that appears to play a role in interspecies interactions of F. nucleatum, particularly with oral streptococci and related Gram-positive species. We designated FN1253 as aid1 (Adherence Inducing Determinant 1). Expression analyses demonstrated that this gene was induced in F. nucleatum single species biofilms, while the presence of representative members of the oral microbiota known to adhere to F. nucleatum triggered its su
