Project description:Gene expression level of Clostridioides difficile (C. difficile) strain R20291 comparing control C. difficile carring pMTL84151 as vector plasmid with C. difficile conjugated with a pMTL84151-03890 gene. Goal was to determine the effects of 03890 gene conjugation on C. difficile strain R20291 gene expression.

Project description:We compared transcriptomes of wild-type and ∆vanS strains of Clostridioides difficile 630 growing in the presence or absence of peptidoglycan-targeting antibiotics, vancomycin or ramoplanin. VanS is a histidine kinase of a two-component system that regulates expression of the vancomycin-induced vanG operon.

Project description:Clostridium difficile is a gram-positive, spore-forming enteric anaerobe which can infect humans and a wide variety of animal species. Recently, the incidence and severity of human C. difficile infection has markedly increased. In this study, we evaluated the genomic content of 73 C. difficile strains isolated from humans, horses, cattle, and pigs by comparative genomic hybridization with microarrays containing coding sequences from C. difficile strains 630 and QCD-32g58. The sequenced genome of C. difficile strain 630 was used as a reference to define a candidate core genome of C. difficile and to explore correlations between host origins and genetic diversity. Approximately 16% of the genes in strain 630 were highly conserved among all strains, representing the core complement of functional genes defining C. difficile. Absent or divergent genes in the tested strains were distributed across the entire C. difficile 630 genome and across all the predicted functional categories. Interestingly, certain genes were conserved among strains from a specific host species, but divergent in isolates with other host origins. This information provides insight into the genomic changes which might contribute to host adaptation. Due to a high degree of divergence among C. difficile strains, a core gene list from this study offers the first step toward the construction of diagnostic arrays for C. difficile.

Project description:Investigation of whole genome gene expression level changes in a Clostridium difficile fur (ferric uptake regulator) mutant, compared to the wild type strain 630 erm. The fur mutant analyzed in this study is further described in Ho and Ellermeier (2015) J. Bacteriology A microarray study using total RNA recovered from three separate wild type cultures of Clostridium difficile 630 erm strain and three separate cultures of a fur mutant strain (ltrA::ermR) were grown in Tryptone-Yeast Extract medium containing 0.25 mM ferric chloride . Each chip measures the expression level of 3,786 of the 3,787 open reading frames of the C. difficile 630 genome with 18 probes (60 oligomers each) for each gene.

Project description:Transcriptomic analysis of C. difficile strain 630 subjected to a clinically relevant heat stress (41°C ) and compared to unstressed cells (37°C ). Heat stress was induced in biological triplicate broth cultures in the early exponential phase (D650nm=0.3) of growth and cells were harvested at late log phase (D650 = 1.1). Goal was to determine effects of mild heat stress on gene expression.
