Journal ArticleDOI
Vaginal microbiome of reproductive-age women
Jacques Ravel,Pawel Gajer,Zaid Abdo,G. Maria Schneider,Sara S. K. Koenig,Stacey L. McCulle,Shara Karlebach,Reshma Gorle,Jennifer Russell,Carol O. Tacket,Rebecca M. Brotman,Catherine C. Davis,Kevin A. Ault,Ligia Peralta,Larry J. Forney +14 more
TL;DR: The inherent differences within and between women in different ethnic groups strongly argues for a more refined definition of the kinds of bacterial communities normally found in healthy women and the need to appreciate differences between individuals so they can be taken into account in risk assessment and disease diagnosis.
Journal ArticleDOI
Temporal Dynamics of the Human Vaginal Microbiota
Pawel Gajer,Rebecca M. Brotman,Guoyun Bai,Joyce M. Sakamoto,Ursel M. E. Schütte,Xue Zhong,Sara S. K. Koenig,Li Fu,Zhanshan Sam Ma,Xia Zhou,Zaid Abdo,Larry J. Forney,Jacques Ravel +12 more
TL;DR: The temporal dynamics of the composition of vaginal bacterial communities in 32 reproductive-age women over a 16-week period revealed the dynamics of five major classes of bacterial communities and showed that some communities change markedly over short time periods, whereas others are relatively stable.
Journal ArticleDOI
Daily temporal dynamics of vaginal microbiota before, during and after episodes of bacterial vaginosis
Jacques Ravel,Rebecca M. Brotman,Pawel Gajer,Bing Ma,Melissa Nandy,Douglas Fadrosh,Joyce M. Sakamoto,Sara S. K. Koenig,Li Fu,Xia Zhou,Roxana J. Hickey,Jane R. Schwebke,Larry J. Forney +12 more
TL;DR: This unique resource of samples and data will contribute to a better understanding of the role that the vaginal microbes have in the natural history of BV and lead to improved diagnosis and treatment.
Journal ArticleDOI
Proof of Concept of Microbiome-Metabolome Analysis and Delayed Gluten Exposure on Celiac Disease Autoimmunity in Genetically At-Risk Infants
Maria Sellitto,Guoyun Bai,Gloria Serena,W. Florian Fricke,Craig Sturgeon,Pawel Gajer,James R. White,Sara S. K. Koenig,Joyce M. Sakamoto,Dustin Boothe,Rachel E. Gicquelais,Deborah Kryszak,Elaine L. Leonard Puppa,Carlo Catassi,Carlo Catassi,Jacques Ravel,Alessio Fasano +16 more
TL;DR: It is shown that infants genetically susceptible to CD who are exposed to gluten early mount an immune response against gluten and develop CD autoimmunity more frequently than at-risk infants in which gluten exposure is delayed until 12 months of age.
Journal ArticleDOI

TL;DR: The analysis of the first complete genome sequences of two important B. megaterium strains, the plasmidless strain DSM319 and QM B1551, which harbors seven indigenous plasmids, and documented extensive gene transfer between theplasmids and the chromosome.
