Oral microbiota contribute to health and disease, and their disruption may influence the course of oral diseases. Here, we used pyrosequencing to characterize the oral bacteriome and mycobiome of 12 HIV-infected patients and matched 12 uninfected controls. The number of bacterial and fungal genera in individuals ranged between 8-14 and 1-9, among uninfected(More)
UNLABELLED Crohn's disease (CD) results from a complex interplay between host genetic factors and endogenous microbial communities. In the current study, we used Ion Torrent sequencing to characterize the gut bacterial microbiota (bacteriome) and fungal community (mycobiome) in patients with CD and their nondiseased first-degree relatives (NCDR) in 9(More)
Candidaauris, a new multidrug-resistant Candida spp. which is associated with invasive infection and high rates of mortality, has recently emerged. Here, we determined the virulence factors (germination, adherence, biofilm formation, phospholipase and proteinase production) of 16 C. auris isolates and their susceptibilities to 11 drugs belonging to(More)
The objective of the current study was to characterize the profile of oral metabolites in HIV-infected patients using metabolomics. Oral wash samples were collected from 12 HIV-infected and 12 healthy individuals (matched for age, sex, and ethnicity), processed, and analyzed by metabolomics. We detected 198 identifiable and 85 nonidentifiable metabolites;(More)
Trichophyton rubrum is the leading pathogen that causes long-lasting skin and nail dermatophyte infections. Currently, topical treatment consists of terbinafine for the skin and ciclopirox for the nails, whereas systemic agents, such as oral terbinafine and itraconazole, are also prescribed. These systemic drugs have severe side effects, including liver(More)
PURPOSE The aim of this study is to assess the effect of lens wear on the formation of soft contact lens-associated Fusarium biofilms and to determine the efficacy of marketed contact lens care products against such biofilms. METHODS Using an established in vitro soft contact lens-Fusarium biofilm model, two clinical Fusarium isolates (F. solani B6914 and(More)
Organisms residing in the oral cavity (oral microbiota) contribute to health and disease, and influence diseases like gingivitis, periodontitis, and oral candidiasis (the most common oral complication of HIV-infection). These organisms are also associated with cancer and other systemic diseases including upper respiratory infections. There is limited(More)
A prospective exploratory study was conducted to characterize the oral mycobiome at baseline and determine whether changes occur after admission to the intensive care unit (ICU). We found that ICU admission is associated with alterations in the oral mycobiome, including an overall increase in Candida albicans.
We report and investigated a case of inadvertent contamination of 125 mice (housed in two germ-free positive-pressurized isolators) with emerging human and coral pathogen Aspergillus sydowii. The infected mice correspond to genetic line SAMP1/YitFc, which have 100% immune predisposition to develop Crohn's disease-like spontaneous pathologies, namely,(More)
BACKGROUND Metabolomics represents a promising approach for discovering novel targets and biomarkers in head and neck squamous cell carcinoma (HNSCC). Here we used metabolomics to identify oral metabolites associated with HNSCC. METHODS Tumor and adjacent normal tissue from surgical resections and presurgical oral washes as well as oral washes were(More)
