RATIONALE Bronchiolitis obliterans syndrome (BOS) is the primary limiting factor for long-term survival after lung transplantation, and has previously been associated with microbial infections. OBJECTIVES To cross-sectionally and longitudinally characterize microbial communities in allografts from transplant recipients with and without BOS using a(More)
BACKGROUND Our view of host-associated microbiota remains incomplete due to the presence of as yet uncultured constituents. The Bacteroidales family S24-7 is a prominent example of one of these groups. Marker gene surveys indicate that members of this family are highly localized to the gastrointestinal tracts of homeothermic animals and are increasingly(More)
Donor T-cell-derived interleukin-17A (IL-17A) can mediate late immunopathology in graft-versus-host disease (GVHD), however protective roles remain unclear. Using multiple cytokine and cytokine receptor subunit knockout mice, we demonstrate that stem cell transplant recipients lacking the ability to generate or signal IL-17 develop intestinal hyper-acute(More)
Over the past decade, technological advances in whole genome amplification, microfluidics, flow sorting, and high-throughput sequencing have led to the development of single-cell genomics. Single-cell genomic approaches are typically applied to anonymous microbial cells with only morphology providing clues to their identity. However, targeted separation of(More)
Bacillus amyloliquefaciens H57 is a bacterium isolated from lucerne for its ability to prevent feed spoilage. Further interest developed when ruminants fed with H57-inoculated hay showed increased weight gain and nitrogen retention relative to controls, suggesting a probiotic effect. The near complete genome of H57 is ~3.96 Mb comprising 16 contigs. Within(More)
