The pathogenic potential of Fusobacterium nucleatum and its significance in
the development of periodontal diseases, as well as in infections in other
organs, have gained new interest for several reasons. First, this bacterium
has the potential to be pathogenic because of its number and frequency in
periodontal lesions, its production of tissue irritants, its synergism with
other bacteria in mixed infections, and its ability to form aggregates with
other suspected pathogens in periodontal disease and thus act as a bridge
between early and late colonizers on the tooth surface. Second, of the
microbial species that are statistically associated with periodontal
disease, F. nucleatum is the most common in clinical infections of other
body sites. Third, during the past few years, new techniques have made it
possible to obtain more information about F. nucleatum on the genetic
level, thereby also gaining better knowledge of the structure and functions
of the outer membrane proteins (OMPs). OMPs are of great interest with
respect to coaggregation, cell nutrition, and antibiotic susceptibility.
This review covers what is known to date about F. nucleatum in general,
such as taxonomy and biology, with special emphasis on its pathogenic
potential. Its possible relationship to other periodontal bacteria in the
development of periodontal diseases and the possible roles played by OMPs
are considered.
