Dengue fever (DF), an arbovirosis caused by Dengue viruses (DV, serotypes 1-4), is responsible for an increasing number of travel-related acute febrile illnesses due to population growth, climate changes, spreading by viremic travellers, and improved laboratory diagnosis. The presence of efficient vectors (mosquito Aedes albopictus) has also been described in temperate regions including Italy which is considered the most heavily infected European country. Normally characterized by non-specific signs and symptoms, DF incidence is probably underestimated, especially in non-endemic countries, but the risk of severe forms is substantial...

BACKGROUND: Men who have sex with men (MSM) have a high lifetime risk of anogenital warts and cancers related to infection with human papillomavirus (HPV). They also benefit less from herd protection than heterosexual males in settings with female-only HPV vaccination. METHODS: We evaluated the potential health impact and cost-effectiveness of offering vaccination to MSM who visit genito-urinary medicine clinics. We used a mathematical model of HPV 6/11/16/18 sexual transmission within an MSM population in England, parameterised with sexual behaviour, GUM attendance, HPV prevalence, HIV prevalence, warts and cancer incidence data...

PURPOSE: Myrrh, the oleo-gum resin of Commiphora molmol, is well known for its anti-inflammatory properties. In different animal models, it protected against DSS-, TNBS- and oxazolone-induced colitis. To date, no information concerning the effect of myrrh on barrier properties are available. Thus, this study investigates the effect of myrrh on paracellular barrier function in the absence or presence of the pro-inflammatory cytokine TNFα. METHODS: Monolayers of human colon cell lines HT-29/B6 and Caco-2 were incubated with myrrh under control conditions or after challenge with the pro-inflammatory cytokine TNFα...

Iron is an essential nutrient for bacterial pathogenesis, but in the host, iron is tightly sequestered, limiting its availability for bacterial growth. Although this is an important arm of host immunity, most studies examine how bacteria respond to iron restriction in laboratory rather than host settings, where the microbiome can potentially alter pathogen strategies for acquiring iron. One of the most important transcriptional regulators controlling bacterial iron homeostasis is Fur. Here we used a combination of RNA-seq and chromatin immunoprecipitation (ChIP)-seq to characterize the iron-restricted and Fur regulons of the biofilm-forming opportunistic pathogen Aggregatibacter actinomycetemcomitans...

Most bacteria in nature exist in multispecies communities known as biofilms. In the natural habitat where resources (nutrient, space, etc.) are usually limited, individual species must compete or collaborate with other neighboring species in order to perpetuate in the multispecies community. The human oral cavity is colonized by >700 microbial species known as the indigenous microbiota. This indigenous flora normally maintains an ecological balance through antagonistic as well as mutualistic interspecies interactions...

Porphyromonas gingivalis is a member of the human oral microbiome abundant in dysbiosis and implicated in the pathogenesis of periodontal (gum) disease. It employs a newly described type-IX secretion system (T9SS) for secretion of virulence factors. Cargo proteins destined for secretion through T9SS carry a recognition signal in the conserved C-terminal domain (CTD), which is removed by sortase PorU during translocation. Here, we identified a novel component of T9SS, PorZ, which is essential for surface exposure of PorU and posttranslational modification of T9SS cargo proteins...

β-mannanase has shown compelling biological functions because of its regulatory roles in metabolism, inflammation, and oxidation. This study separated and purified the β-mannanase from Bacillus subtilis BE-91, which is a powerful hemicellulose-degrading bacterium using a "two-step" method comprising ultrafiltration and gel chromatography. The purified β-mannanase (about 28.2 kDa) showed high specific activity (79, 859.2 IU/mg). The optimum temperature and pH were 65°C and 6.0, respectively. Moreover, the enzyme was highly stable at temperatures up to 70°C and pH 4...

: More than 75 'species-level' phylotypes of spirochete bacteria belonging to the genus Treponema reside within the human oral cavity. The majority of these oral treponeme phylotypes correspond to as-yet uncultivated taxa, or strains of uncertain standing in taxonomy. Here, we analyze phylogenetic and taxonomic relationships between oral treponeme strains using a multilocus sequence analysis (MLSA) scheme based on the highly-conserved 16S rRNA, pyrH, recA and flaA genes. We utilize this MLSA scheme to analyze genetic data from a curated collection of oral treponeme strains (n=71) of diverse geographical origins...

INTRODUCTION: Gingivitis affects an estimated 80% of the population, and is characterized as the world's most predominant inflammatory periodontal disease. Without intervention, gingivitis can advance to alveolar bone loss. Therefore, the primary goal in patients suffering with gingivitis is to control plaque buildup and soft tissue inflammation. Current guidelines consider chlorhexidine as the gold standard in the prevention and treatment of gingivitis. However, negative side effects of chlorhexidine, including oral mucosal erosion, discoloration of teeth, and bitter taste, provide an opportunity for alternative medications...

In the global context of increasing colonic diseases, colon specific oral drug delivery systems have shown promise as an effective therapeutic modality. Herein, we developed a mesoporous silica nanoparticle (MSN) based enzyme responsive materials for colon specific drug delivery. We have utilized guar gum, a natural carbohydrate polymer as a capping layer to contain a model drug, such as 5-flurouracil (5FU) within the mesoporous channels of MSN. Analytical characterization including electron microscopy, PXRD, nitrogen sorption, thermogravimetric analysis and FTIR, confirmed that the synthesized MSN with size less than 100nm is of MCM-41type...

Periodontitis is the chronic destructive disease of the periodontium (Gums) caused by host bacterial interactions. The effect of such host bacterial interactions in oral cavity also evokes a systemic response. Numerous studies have found common mechanisms of destruction for periodontal diseases and other chronic diseases like diabetes mellitus, atherosclerosis, respiratory diseases, and adverse pregnancy outcomes. Oral colonization by respiratory pathogens appears to be a risk factor for development of respiratory diseases and oral interventions aimed at reducing oral bacterial count have resulted in reduced incidence of these reparatory illness...
