MORENO, Sandra  y  CONTRERAS, Adolfo. Functional differences of Porphyromonas gingivalis Fimbriae in determining periodontal disease pathogenesis: a literature review. Colomb. Med. [online]. 2013, vol.44, n.1, pp.48-56. ISSN 1657-9534.

Porphyromonas gingivalis is implicated in chronic and aggressive periodontitis. This bacterium has numerous virulence factors and one is the Fimbriae, which is quite important for bacterial colonization. Fimbriae are appendices that anchor to the bacterial wall and are comprised of the protein FimBriline encoded by the FimA gene. Thus far, six genotypes have been identified, FimA I to V and Ib. Genotypes II and IV are associated with periodontal disease, while genotype I is related to gingival health. Genotype identification of P. gingivalis FimA in periodontitis would be important to confirm the pathogenic genotypes and to establish risk at population level. This review is about the P. gingivalis FimA genotype prevalence worldwide. A systematic search using Pubmed, Hinary, and Science Direct within the following descriptors: Porphyromonas gingivalis, bacterial adhesion, periodontitis, Fimbriae, FimA, genotipification was performed to April 2011.

Palabras clave : Porphyromonas gingivalis; bacterial adhesion; periodontitis; Fimbriae; FimA; genotipification.
