“In this study, we present an integrated, iterative approach of computational modeling, in vitro experiments, metabolomics and genomic analysis to accelerate the identification of metabolic capabilities for poorly characterized (anaerobic) microorganisms.”

Pregnancy and birth

Screen shot 2014-07-14 at 12.26PM, Jul 14Effect of chemotherapy on the microbiota and metabolome of human milk, a case report – Camilla Urbaniak – Microbiome

“Mature milk was collected every two weeks over a four month period from a lactating woman undergoing chemotherapy for Hodgkin’s lymphoma. Mature milk was also collected from healthy lactating women for comparison. Microbial profiles were analyzed by 16S sequencing and the metabolome by gas chromatography-mass spectrometry.”

Animal models

Clara Belzer miceDynamics of the Microbiota in Response to Host Infection – Clara Belzer – PLOS ONE

“Employing a murine model of infectious colitis with the pathogen Citrobacter rodentium, we generated a 2-month time-series of 16S rDNA gene profiles, and quantitatively cultured commensals, from multiple intestinal sites in infected and uninfected mice. “

Prune juice animal modelCarbohydrate-Free Peach (Prunus persica) and Plum (Prunus domestica) Juice Affects Fecal Microbial Ecology in an Obese Animal Model – Giuliana D. Noratto – PLOS ONE

“Fecal samples were obtained after 11 weeks of fruit or control juice administration. Real-time PCR and 454-pyrosequencing were used to evaluate changes in fecal microbiota. Over 1,500 different Operational Taxonomic Units at 97% similarity were detected in all rats.”
