BACKGROUND AND AIM Fusobacterium enrichment has been associated with colorectal cancer development. Ulcerative colitis (UC) associated tumorigenesis is characterized as high degree of methylation accumulation through continuous colonic inflammation. The aim of this study was to investigate a potential link between Fusobacterium enrichment and DNA methylation accumulation in the inflammatory col...
BACKGROUND Numerous cancers have been linked to microorganisms. Given that colorectal cancer is a leading cause of cancer deaths and the colon is continuously exposed to a high diversity of microbes, the relationship between gut mucosal microbiome and colorectal cancer needs to be explored. Metagenomic studies have shown an association between Fusobacterium species and colorectal carcinoma. Her...
lacterial surface structures play a critical role in the initiation of infectious diseases. Various surface ^ components of pathogenic bacteria have been reported to be involved in host injury. There is a great deal of evidence incriminating certain Gram-negative, anaerobic bacteria present in the gingival crevice as etiologic agents of human periodontal diseases. We have isolated endotoxic cel...
7-Aminomethyl-7-deazaguanine (preQ(1)) sensitive mRNA domains belong to the smallest riboswitches known to date. Although recent efforts have revealed the three-dimensional architecture of the ligand-aptamer complex less is known about the molecular details of the ligand-induced response mechanism that modulates gene expression. We present an in vitro investigation on the ligand-induced folding...
Fifteen clinical isolates of Fusobacterium species were studied to determine their quality of growth on five agar media, their susceptibility to penicillin, cephalothin, cefoxitin, and cefotaxime, the inoculum effect, and the presence of L forms and beta-lactamase. Wilkins-Chalgren agar supported confluent growth best, but Fusobacterium nucleatum exhibited poor growth on all agar media. Most is...
BACKGROUND Fusobacterium necrophorum may cause a number of clinical syndromes, collectively known as necrobacillosis. Meningitis is a significant cause of mortality, rarely reported in the adult population. CASE PRESENTATION We report a fatal case of meningitis, caused by Fusobacterium necrophorum, secondary to otitis media in an alcoholic male. Diagnosis was delayed due to the typical slow g...
Lemierre syndrome is defined by septic thrombophlebitis of the internal jugular vein caused by Fusobacterium. Historically, these infections originate from the oropharynx and typically are seen in older children, adolescents and young adults. More recently, otogenic sources in younger children have been described with increasing frequency. We present a case of a two-year old, who initially deve...
UNLABELLED INTRODUCTION Post-partum, post-sterilization tubo-ovarian abscess is a rare event. Fusobacterium necrophorum subspecies funduliforme, a normal flora found mainly in the oral cavity, appears to be the etiologic organism. CASE PRESENTATION In this case report, a 25-year-old Thai woman had a post-partum, post-sterilization tubo-ovarian abscess caused by the strictly anaerobic bacte...
Hyperbaric oxygen exposures were evaluated for treatment of progressive liver abscesses produced by intraperitoneal injection of combined cultures of Fusobacterium necrophorum plus either Bacteroides fragilis subsp. fragilis or Fusobacterium nucleatum in a mouse model. Infected control and hyperbaric oxygen-exposed mice were autopsied 5 or 6 weeks after inoculation of bacteria and were assigned...
