Expression analysis of Bacteroides fragilis NCTC 9343 delta-gmd-fcl delta-fkp and B. fragilis NCTC 9343 delta-lfg

Project description:Investigation of whole genome gene expression level changes in a Bacteroides fragilis NCTC 9343 delta-gmd-fcl delta-fkp mutant strain and a Bacteroides fragilis NCTC 9343 delta-lfg mutant strain, each as compared to the wild-type strain. The mutations engineered into these strains interfere with B. fragilis protein glycosylation.

Expression analysis of Bacteroides fragilis NCTC 9343 delta-ungD1 delta-ungD2

Project description:Investigation of whole genome gene expression level changes in a Bacteroides fragilis NCTC 9343 delta-ungD1 delta-ungD2 double mutant compared to the wild-type strain. Keywords: expression analysis A six chip study using total RNA recovered from three separate wild-type cultures of Bacteroides fragilis NCTC 9343 and three separate cultures of a double mutant strain, Bacteroides fragilis NCTC 9343 delta-ungD1 delta-ungD2, in which ungD1 (BF1706) and ungD2 (BF2848) are deleted. Each chip measures the expression level of 4,302 genes from Bacteroides fragilis NCTC 9343 and the associated plasmid pBF9343 with fourteen 24-mer probe pairs (PM/MM) per gene, with three-fold technical redundancy.

RNA-sequencing of Clostridioides difficile WT and luxS mutant both during mono-culture biofilms and co-culture biofilms with Bacteroides fragilis

Project description:5 conditions for RNA-sequencing: Mono-culture biofilms of C. difficile WT, C. difficile luxS mutant (insertional ClosTron mutant as described in DOI: 10.1128/JB.01980-12), B. fragilis (PRJEB29695), and co-cultures biofilms of C. difficile WT and luxS mutant with B. fragilis. These were used to compare differences between C. difficile WT and luxS during mono-culture biofilms, as well transcriptomic differences for both C. difficile and B. fragilis during co-culture.

Outer Membrane Vesicles Secreted by Bacteroides fragilis Inhibit CFTR Chloride Secretion by Human Colon Organoids

Project description:The goals of this study were to develop a model to study host pathogen interactions in primary human colon organoids and to test the hypothesis that Bacteroides fragilis toxin (BFT-2) secreted in outer membrane vesicles (OMVs) modulates mucosal immunity and CFTR Cl- secretion. Since Bacteroides species often resides in mucus, OMVs are likely to represent a mechanism of communication between Bacteroides and the host. Two strains of Bacteroides were studied, Enterotoxigenic Bacteroides fragilis (ETBF), which produces BFT-2, and the non-toxigenic Bacteroides fragilis strain NCTC 9343 (NTBF) that does not produce BFT-2. We also utilized two additional strains of Bacteroides fragilis: one in which bft-2 was knocked out (ETBF Δbft), and one that was engineered to contain bft-2 (NTBF+bft). We report that most Bacteroides fragilis OMVs reduced CFTR Cl- secretion but had no effect on tight junction or cell adhesion proteins, transepithelial resistance (TER) or cytokine secretion by primary human colon organoids. We conclude that OMVs secreted by Bacteroides can be an important mechanism of host pathogen interactions in the colon by reducing CFTR Cl- secretion.

Expression analysis of Bacteroides fragilis NCTC 9343 delta-ungD1 delta-ungD2 delta-PSH acapsular mutant

Project description:Investigation of whole genome gene expression level changes in a Bacteroides fragilis NCTC 9343 delta-ungD1 delta-ungD2 delta-PSH triple mutant, compared to the wild-type strain. The mutations engineered into this strain render it acapsular. The mutants analyzed in this study are further described in Coyne, M. J., M. Chatzidaki-Livanis, L. C. Paoletti, and L. E. Comstock. 2008. Role of glycan synthesis in colonization of the mammalian gut by the bacterial symbiont Bacteroides fragilis. PNAS 105(35):13098-13103 (PID 18723678). A six chip study using total RNA recovered from three separate wild-type cultures of Bacteroides fragilis NCTC 9343 and three separate cultures of a triple mutant strain, Bacteroides fragilis NCTC 9343 delta-ungD1 delta-ungD2 delta-PSH, in which ungD1 (BF1706), ungD2 (BF2848), and six genes (BF3454 through BF3459) of the PSH capsular polysaccharide locus are truncated or deleted entirely. Each chip measures the expression level of 4,302 genes from Bacteroides fragilis NCTC 9343 and the associated plasmid pBF9343 with fourteen 24-mer probe pairs (PM/MM) per gene, with three-fold technical redundancy.
