Changes in microbiome have been reported recently in psoriasis lesions compared to healthy surround skin. Preliminary data showed that systemic treatments of psoriasis induce modification of the skin microbiome that becomes similar to healthy individuals after successful treatment. The causative role of microbiome in psoriasis remains in debate. The modification of skin microbiome is suspected to be able to activate the innate immune response, namely natural killers (NKs) and i...
Samples will be collected to determine human genetic variation, fecal and oral microbial communities, and metabolome products. Several evolutionary and ecological diversity metrics will be distilled to test: a) if microbiome variation within each ethnicity is less than that between ethnicities; b) if microbiome variation is finely structured according to genetic relatedness; and c) if dietary variation impacts human genome x microbiome associations.
The human oral cavity is a diverse habitat that contains approximately 700 prokaryotic species. The oral microbiome is comprised of 44% named species, 12% isolates representing unnamed species, and 44% phylotypes known only from 16S rRNA based cloning studies (http://www.homd.org/). Species from 11 phyla have been identified: Firmicutes, Bacteroidetes, Proteobacteria, Actinobacteria, Spirochaetes, Fusobacteria, TM7, Synergistetes, Chlamydiae, Chloroflexi and SR1 (http://www.hom...
Investigators plan to perform a pilot study that aims to characterize the microbiome of human vitiligo patients with both active and stable disease and compare this to the microbiome of age and sex matched controls. The investigators aim to answer the question whether the gut and skin microbiome of patients with vitiligo differs from the general population.
The SHAPES-Captivity study seeks to identify metagenomic components of the intestinal microbiome shared by human beings and captive great apes living in proximity and in direct, daily contact. The investigators will determine the phylogenetic diversity of enterotypes (bacterial and viral) shared between human beings and great apes and will link these results with participant-observations of caretakers' activities (and contacts) with these great apes.
The human microbiome is composed of unique groups of microorganisms occupying distinct habitats distributed throughout the human body. The Human Microbiome Project recently evaluated the bacterial composition of the microbiome in 18 (for women) and 15 (for men) body sites. Much initial attention in the field of microbiome research has focused on the bacterial contribution to a "healthy" microbiome. However, it is clear that other microorganisms, including fungi and viruses, are...
Atopic dermatitis is a chronic relapsing disease with acute flares. The standard therapy is to treat acute flares using topical medications. The two most common classes of topical medications for atopic dermatitis are topical corticosteroids and topical calcineurin inhibitors. Pimecrolimus and topical corticosteroids exert their activity by different mechanisms, there may be a synergistic effect of the combination therapy. Therefore, a combination therapy may provide a...
This non-treatment study will examine how commonly used prescription or over-the-counter medications may influence mood and medication preference.
This study should reveal differences in composition of luminal and mucosa-associated microbiome of the human gastrointestinal tract.Therefore bacterial species of different intestinal location sites (small intestine and colon) isolated of biopsies were compared to bacterial composition of stool samples. Additionally the bacterial composition of healthy persons, patients with inflammatory bowel disease and with liver disease (liver cirrhosis) will be compared to detect influence...
The consumption of fermented soy foods can alter the human microbiome and may confer health benefits. Researchers propose a line of inquiry to assess the effects of Q-Can Plus ("QC") fermented soy beverage in humans, assessing immunological, microbiological, and clinical parameters.
The use of antibiotics has saved millions of human lives, however consumption of antibiotics can select for antibiotic resistant organisms and may lead to changes in commensal microbiome. This study is designed to estimate the effect of antibiotic consumption on microbiome in a rural region of rural Burkina Faso. Changes in the intestinal and nasopharyngeal microbiome and resistome following a short course of antibiotics will be measured.
Soylent 2.0 is a popular meal replacement drink that is used to supplement or replace one's regular diet. Soylent is designed to fully fulfill one's nutritional needs, but its impact on the human microbiome remains unknown. This study aims to track the composition of participants' gut microbiomes before, during, and after Soylent consumption to more holistically understand its impact on microbiome health. We predict that a short term Soylent-based diet will induce observable an...
Microbial communities are key components of human environment. Consequently, human gut microbiome have been extensively studied providing a better understanding of the relations between bacterial populations and host physiology. However, a typical analysis tends to elude the complexity of the mixes in term of species, strains, as well as extra-chromosomal DNA molecules such as and phages. MetaKids project aims at bringing, at an unprecedented resolution, a new view of those pop...
