[HTML][HTML] Standardized multi-omics of Earth's microbiomes reveals microbial and metabolite diversity

JP Shaffer, LF Nothias, LR Thompson, JG Sanders… - Nature …, 2022 - nature.com
Despite advances in sequencing, lack of standardization makes comparisons across studies
challenging and hampers insights into the structure and function of microbial communities …

[PDF][PDF] Pan-cancer analyses reveal cancer-type-specific fungal ecologies and bacteriome interactions

…, S Wandro, G Perry, R Ariel, A Meltser, JP Shaffer… - Cell, 2022 - cell.com
Cancer-microbe associations have been explored for centuries, but cancer-associated fungi
have rarely been examined. Here, we comprehensively characterize the cancer mycobiome …

[HTML][HTML] Enhancing untargeted metabolomics using metadata-based source annotation

…, A Tripathi, MJ Meehan, K Dorrestein, JP Shaffer… - Nature …, 2022 - nature.com
Human untargeted metabolomics studies annotate only ~10% of molecular features. We
introduce reference-data-driven analysis to match metabolomics tandem mass spectrometry (…

Consumption of fermented foods is associated with systematic differences in the gut microbiome and metabolome

BC Taylor, F Lejzerowicz, M Poirel, JP Shaffer, L Jiang… - Msystems, 2020 - Am Soc Microbiol
Lifestyle factors, such as diet, strongly influence the structure, diversity, and composition of
the microbiome. While we have witnessed over the last several years a resurgence of interest …

A comparison of six DNA extraction protocols for 16S, ITS and shotgun metagenomic sequencing of microbial communities

JP Shaffer, CS Carpenter, C Martino, RA Salido… - …, 2022 - Future Science
Microbial communities contain a broad phylogenetic diversity of organisms; however, the
majority of methods center on describing bacteria and archaea. Fungi are important symbionts …

[HTML][HTML] SARS-CoV-2 detection status associates with bacterial community composition in patients and the hospital environment

…, MC Salas Garcia, LY Chiang, RA Salido, JP Shaffer… - Microbiome, 2021 - Springer
Background SARS-CoV-2 is an RNA virus responsible for the coronavirus disease 2019 (COVID-19)
pandemic. Viruses exist in complex microbial environments, and recent studies …

[HTML][HTML] An endohyphal bacterium (Chitinophaga, Bacteroidetes) alters carbon source use by Fusarium keratoplasticum (F. solani species complex, Nectriaceae)

JP Shaffer, JM U'Ren, RE Gallery, DA Baltrus… - Frontiers in …, 2017 - frontiersin.org
Bacterial endosymbionts occur in diverse fungi, including members of many lineages of

Phylogeny-aware analysis of metagenome community ecology based on matched reference genomes while bypassing taxonomy

…, P Das, JP Shaffer, F Lejzerowicz, P Belda-Ferre… - Msystems, 2022 - Am Soc Microbiol
We introduce the operational genomic unit (OGU) method, a metagenome analysis strategy
that directly exploits sequence alignment hits to individual reference genomes as the …

Early life gut microbiota is associated with rapid infant growth in Hispanics from Southern California

TL Alderete, RB Jones, JP Shaffer, EA Holzhausen… - Gut …, 2021 - Taylor & Francis
We aimed to determine if the newborn gut microbiota is an underlying determinant of early
life growth trajectories. 132 Hispanic infants were recruited at 1-month postpartum. The infant …

Postnatal exposure to ambient air pollutants is associated with the composition of the infant gut microbiota at 6-months of age

…, EA Holzhausen, ZEM Morgan, N Naik, JP Shaffer… - Gut …, 2022 - Taylor & Francis
Epidemiological studies in adults have shown that exposure to ambient air pollution (AAP)
is associated with the composition of the adult gut microbiome, but these relationships have …
