Fusobacterium nucleatum is a
oral cavity, that plays a role in periodontal disease. This organism is commonly recovered from different monocultured microbial and mixed infections in humans and animals. In health and disease, it is a key component of periodontal plaque due to its abundance and its ability to coaggregate with other bacteria species in the oral cavity.[1][2]
Preterm births
Research implicates periodontal disease caused by F. nucleatum with
vaginal microbiome, especially in women with a condition known as bacterial vaginosis.[4] Both F. nucleatum vaginal colonization and bacterial vaginosis also have been linked with preterm birth and infections within the uterus.[5] Thus, preterm birth arising by infections caused by F. nucleatum could also arise from invasive infection into the uterine tissue originating from the colonized vagina.[citation needed

Colon cancer
F. nucleatum has a demonstrated association with
E-cadherins via a FadA, an outer membrane protein.[7] Additionally, a surface expressed lectin called Fap2 mediates F. nucleatum adherence to colorectal cancer cells that express Gal/GalNAc moieties on their surface. Binding via Fap2 has also been shown to up-regulate production of cytokines associated with higher rates of metastasis.[8]
Natural competence
Type IV pili facilitate natural competence in F. nucleatum[9]. Natural competence involves three principal stages: (1) Uptake of exogenous DNA and transport to the cytoplasm, (2) homologous DNA that has been taken up can integrate into the recipient cell genome by homologous recombination, and (3) the integrated exogenous DNA can express gene functions[9].
