Project description:We aim to determine if mice in our mouse colony had similar of different microbiomes. To do this, we perfromed 16S sequencing of stool from unifected mice of the gentotypes listed below. We also looked at how infection causes dysbiosis of the mircobiome, measuring 16S sequencing over a C.rodentium infection timecourse.
Project description:Total DNA was extracted from stool specimens, amplified to collect amplicons of variable V3–V4 regions of the bacterial 16s rRNA gene and sequenced with MiSeq (2x300bp) Illumina platform.
Project description:Total DNA was extracted from saliva and stool of the patients, amplified to collect amplicons of variable V3–V4 regions of the bacterial 16s rRNA gene and sequenced with MiSeq (2x300bp) Illumina platform.
Project description:Total DNA was extracted from the stool of the patients, amplified to collect amplicons of variable V3–V4 regions (primers 341F and 805R) of the bacterial 16s rRNA gene and sequenced with MiSeq (2x300bp) Illumina platform.
Project description:Neonatal necrotizing enterocolitis (NEC) is a deadly and unpredictable gastrointestinal disease, for which no biomarkers exist. We aimed to describe the methylation patterns in stool and colon from infants with NEC.
Project description:A three-stage continuous fermentative system was developed to simulate and control physicochemical factors of the gut biology. Inoculation was of each reactor was performed from a human fecal sample which was initially amplified with a batch procedure. Samples from the initial feces, the batch and from the bioreactors media were collected to extract bacterial DNA. 16S PCR amplification was performed to assess the microbial diversity at the family level using the HuGChip. Amplified DNA was purified and labelled with either Cy3 or Cy5 dye and hybridized on the microarray. A 5 chip study was realized, each corresponding to hybridization with 250ng of labelled 16S rRNA gene amplicons from either the initial stool, the batch inoculum or fermentative medium different compartments of the simulated colon (Proximal, Transversal and Distal). Each probe (4441) was synthetized in three replicates.
Project description:Stool samples from four patients with Biliary atresia (BA) and three patients with neonatal cholestasis of other etiologies (non-BA) were analyzed by overlapping DIA-MS.
