Prevention of implant-associated infections at an early stage of surgery is highly desirable for the long-term efficacy of implants in dentistry and orthopedics. Infection prophylaxis using conventional antibiotics is becoming less effective due to the development of bacteria resistant to multiple antibiotics. An ideal strategy to conquer bacterial infections is the local delivery of antibacterial agents. Therefore, antimicrobial peptide (AMP) eluting coatings on implant surfaces is a promising alternative...

The possibility of targeting the hypervariable region V3 of the 16S rRNA gene using Ion Torrent Personal Genome Machine (PGM) could provide a complete analysis of subgingival plaque samples, potentially able to identify microbiological species missed by culture-based methods. A 16-year-old female smoker patient, affected by localized aggressive periodontitis, underwent a full-mouth disinfection protocol and was inserted in a 3-month recall program. Microbiological samples were collected at baseline and at 30, 100, 365 days follow-up and analyzed by Ion Torrent PGM...

The underlying mechanism of Fusobacterium nucleatum (Fn) in the carcinogenesis of colorectal cancer (CRC) is poorly understood. Here, we examined Fn abundance in CRC tissues, as well as β-catenin, TLR4 and PAK1 protein abundance in Fn positive and Fn negative CRCs. Furthermore, we isolated a strain of Fn (F01) from a CRC tissue and examined whether Fn (F01) infection of colon cancer cells activated β-catenin signaling via the TLR4/P-PAK1/P-β-catenin S675 cascade. Invasive Fn was abundant in 62.2% of CRC tissues...

Inflammation and microbiota are critical components of intestinal tumorigenesis. To dissect how the microbiota contributes to tumor distribution, we generated germ-free (GF) ApcMin/+ and ApcMin/+;Il10-/- mice and exposed them to specific-pathogen-free (SPF) or colorectal cancer-associated bacteria. We found colon tumorigenesis significantly correlated with inflammation in SPF housed ApcMin/+;Il10-/-, but not ApcMin/+ mice. In contrast, small intestinal neoplasia development significantly correlated with age in both ApcMin/+;Il10-/- and ApcMin/+ mice...

BACKGROUND: The incidence of halitosis has a prevalence of 22-50% throughout the world and is generally caused by anaerobic oral microorganisms, such as Fusobacterium nucleatum, Clostridium perfringens, and Porphyromonas gingivalis. Previous investigations on the structure-activity relationships of ginsenosides have led to contrasting results. Particularly, the antibacterial activity of less polar ginsenosides against halitosis-related bacteria has not been reported. METHODS: Crude saponins extracted from the Panax quinquefolius leaf-stem (AGS) were treated at 130°C for 3 h to obtain heat-transformed saponins (HTS)...

The human oral microbiome has been known to show strong association with various oral diseases including oral cancer. This study attempts to characterize the community variations between normal, oral potentially malignant disorders (OPMD) and cancer associated microbiota using 16S rDNA sequencing. Swab samples were collected from three groups (normal, OPMD and oral cancer) with nine subjects from each group. Bacteria genomic DNA was isolated in which full length 16S rDNA were amplified and used for cloned library sequencing...

BACKGROUND: The strongest risk factor for oesophageal adenocarcinoma is reflux disease, and the rising incidence of this coincides with the eradication of Helicobacter pylori, both of which might alter the oesophageal microbiota. We aimed to profile the microbiota at different stages of Barrett's carcinogenesis and investigate the Cytosponge as a minimally invasive tool for sampling the oesophageal microbiota. METHODS: In this case-control study, 16S rRNA gene amplicon sequencing was done on 210 oesophageal samples from 86 patients representing the Barrett's oesophagus progression sequence (normal squamous controls [n=20], non-dysplastic [n=24] and dysplastic Barrett's oesophagus [n=23], and oesophageal adenocarcinoma [n=19]), relevant negative controls, and replicates on the Illumina MiSeq platform...

BACKGROUND: We investigated the single nucleotide polymorphism (SNP) context of a previously identified periodontitis-associated locus and examined its association with microbial, biological and periodontal disease clinical parameters. METHODS: We annotated a 200Kb-spanning region of 1q12 previously highlighted in a genome-wide association scan among 4,910 European American individuals (SNP rs1633266). Two haplotype blocks were selected. We examined the association of these polymorphisms with data on microbial plaque composition, gingival crevicular fluid (GCF)-interleukin (IL)-1β levels and clinical parameters of periodontal disease...

Background.: Hidradenitis suppurativa (HS) is a frequent and severe disease of the skin, characterized by recurrent or chronic skinfolds suppurative lesions with a high impact on quality of life. Although considered inflammatory, antimicrobial treatments can improve or lead to clinical remission of HS, suggesting triggering microbial factors. Indeed, mixed anaerobic microbiota are associated with a majority of HS lesions. The aim of this study was to characterize the landscape of anaerobic infections in HS using high throughput sequencing...

Animal bite wounds affect more than 5 million Americans resulting in 300,000 Emergency Department visits, 10,000 hospitalizations and untold number of physician office visits annually. Various forms of topical therapy are empirically self-employed by many patients prior to seeking medical attention. Pexiganan, a 22-amino acid synthetic cationic analogue of peptide magainin II, acts by selectively damaging bacterial cell membranes. We determined the MICs for pexiganan and other antimicrobial agents often used for treatment of bite wounds...

Unhealthy diets, and ensuing weight gain, predispose individuals to the development of esophageal adenocarcinoma. We examined the effect of chronic high fat diet (HFD) on the esophageal microbiota of Sprague Dawley rats using Illumina MiSeq amplicon sequencing (V4, 515 F/806 R) and on esophageal expression of IL18, PTGS2, PPARA, FFAR3, and CRAT. The relationships among metabolic parameters, esophageal microbiota, and host gene expression were determined. We observed a significant difference between the upper and lower esophageal microbiota in control fed rats, emphasized by enrichment of Lactobacillus species in the lower esophagus...

Fusobacterium nucleatum plays a key role in several diseases such as periodontitis, gingivitis, appendicitis, and inflammatory bowel disease (IBD). The development of antibiotic resistance by this bacterium demands novel therapeutic intervention. Our recent study has reported UDP-N-acetylglucosamine 1-carboxyvinyltransferase (MurA) as one of the potential target proteins in F. nucleatum. In this study, we proposed two novel MurA inhibitors through in silico screening and evaluated their mode of inhibition by in vitro experiments...

Lemierre's syndrome (LS) is an uncommon condition with oropharyngeal infections, internal jugular vein thrombosis, and systemic metastatic septic embolization as the main features. Fusobacterium species, a group of strictly anaerobic Gram negative rod shaped bacteria, are advocated to be the main pathogen involved. We report a case of LS complicated by pulmonary embolism and pulmonary septic emboli that mimicked a neoplastic lung condition. A Medline search revealed 173 case reports of LS associated with internal jugular vein thrombosis that documented the type of microorganism...
