Fusobacterium nucleatum is a prominent member of the oral microbiota and is a common cause of human infection. F. nucleatum includes five subspecies: polymorphum, nucleatum, vincentii, fusiforme, and animalis. F. nucleatum subsp. polymorphum ATCC 10953 has been well characterized phenotypically and, in contrast to previously sequenced strains, is amenable to gene transfer. We sequenced and anno...

A total of 22 strains of Treponema spp. including members of all four named human oral species were tested for coaggregation with 7 strains of oral fusobacteria, 2 strains of nonoral fusobacteria, and 45 strains of other oral bacteria, which included actinobacilli, actinomyces, capnocytophagae, eubacteria, porphyromonads, prevotellae, selenomonads, streptococci, and veillonellae. None of the tr...

The pathogenesis of periodontitis involves the interplay of microbiota present in the subgingival plaque and the host responses. Inflammation and destruction of periodontal tissues are considered to result from the response of a susceptible host to a microbial biofilm containing gramnegative pathogens. Antimicrobial peptides are important contributors to maintaining the balance between health a...

SUMMARY Our gastrointestinal tract is colonized by trillions of microbes. There growing recognition that commensal bacteria can promote the development colorectal adenomas and cancer. For example, bacterial plaques are strongly associated with in familial adenomatous polyposis (Science 2018;359:592-597), fusobacterium cancer liver metastasis.(Science 2017;358:1443-1448)

The Reproducibility Project: Cancer Biology seeks to address growing concerns about reproducibility in scientific research by conducting replications of selected experiments from a number of high-profile papers in the field of cancer biology. The papers, which were published between 2010 and 2012, were selected on the basis of citations and Altmetric scores (Errington et al., 2014). This Regist...

Lemierre's syndrome is a rare disorder of young adults caused by the anaerobic bacterium, Fusobacterium necrophorum and occasionally by other Fusobacterium species (F. nucleatum, F. mortiferum and F. varium etc). The condition is characterized by a primary oropharyngeal infection with evidence of septic thrombophlebitis, exhibited by positive blood cultures, clinical or radiographic evidence of...

We present the case of a 17-year-old boy who developed a deep space neck infection following cervical trauma. He was initially managed conservatively with broad-spectrum antibiotics, but when he failed to improve clinically, he required surgical drainage. Wound cultures grew Fusobacterium necrophorum, an uncommon pathogen that can cause pediatric deep neck space infections, especially when it i...

Propolis extract antimicrobial activity against periodontopathic (ATCC) bacteria was investigated “in vitro”. Bacterial strains tested were: Prevotella intermedia, Prevotella melaninogenica, Porphyromonas gingivalis, Actinobacillus actinomycetemcomitans, Capnocytophaga gingivalis and Fusobacterium nucleatum. Minimal inhibitory concentration (MIC) for the strains tested was determined using the ...
