Project description:Purpose:To uncover the related mechanisms underlie virulence attenuation of Brucella canis MucR mutant strain. Methods:Three Brucella canis RM6/66 strains and three Brucella canis ΔmucR strains were grown in TSB at 37℃ until the log phase was reached, total RNA was isolated using the TRIzol according to the manufacturer’s instructions.The sequencing library of each RNA sample was prepared by using NEB Next Ultra Directional RNA Library Prep Kit for Illumina as recommended by the manufacturer. An Illumina platform was used to perform the transcriptome sequencing. Results: The results revealed that expressions of 694 genes were significantly different between RM6/66 and ΔmucR. Data analysis showed that in the COG term, the different expressed genes involved in translation, ribosomal structure and biogenesis, signal transduction mechanisms, energy production and conversion, intracellular trafficking, secretion, and vesicular transport, and extracellular structures were significantly affected. Pathway enrichment analysis indicated that the genes involved in ribosome, oxidative phosphorylation, aminoacyl-tRNA biosynthesis and protein export were significantly enriched.

Project description:Toxocariasis is an important, neglected zoonosis caused mainly by Toxocara canis. Although our knowledge of helminth molecular biology is improving through completed draft genome projects, there is limited detailed information on the molecular biology of Toxocara species. Here, transcriptomic sequencing of male and female adult T. canis and comparative analyses were conducted. For each sex, two-thirds (66-67%) of quality-filtered reads mapped to the gene set of T. canis, and at least five reads mapped to each of 16,196 (87.1%) of all 18,596 genes, and 321 genes were specifically transcribed in female and 1467 in male T. canis. Genes differentially transcribed between the two sexes were identified, enriched biological processes and pathways linked to these genes established, and molecules associated with reproduction and development predicted. In addition, small RNA pathways involved in reproduction were characterized, but there was no evidence for piwi RNA pathways in adult T. canis. The results of this transcriptomic study should provide a useful basis to support investigations of the reproductive biology of T. canis and related nematodes.

Project description:In this study the transcriptomes of Acinetobacter baumannii strains ATCC 17978 and 17978hm were compared. Strain 17978hm is a hns knockout derivative of strain ATCC 17978. Strain 17978hm displays a hyper-motile phenotype on semi-solid Mueller-Hinton (MH) media (0.25% agar). ATCC 17978 and 17978hm from an 37C overnight culture were transferred to the centre of the semi-solid MH plate and incubated at 37C for 8 hours. Only 17978hm cells displayed a motile phenotype and covered the complete surface of the plate. These motile 17978hm cells and the non-motile wild-type ATCC 17978 cells were harvested and RNA was isolated. The comparative transcriptome analysis was performed using the FairPlay labeling kit and a custom made Agilent MicroArray with probes designed to coding regions of the ATCC 17978 genome. The data was analyzed using Agilent GeneSpring GX9 and the significance analysis of microarray MS Excel add-on.

Project description:Helicobacter cinaedi is an emerging bacterial pathogen of immunosuppressed individuals. The species is traditionally thought to require an H2-enhanced microaerobic atmosphere for growth, although it can proliferate under aerobic conditions when co-cultured with epithelial monolayers or supplemented with certain metabolites (notably, L-lactate). The goal of this experiment was to assess the global transcription changes that occur in the H. cinaedi type strain (ATCC BAA-847) under various media and atmospheric conditions. These include bacterial monoculture, as well as co-culture with Caco-2 intestinal epithelial cells. In total, Illumina mRNA-seq (stranded, paired-end) was performed on H. cinaedi grown under 9 in vitro culture conditions (4-5 biologic replicates per condition).

Project description:Corynebacterium glutamicum strain ATCC 21831 is a producer of L-arginine that was created by random mutagenesis. It is resistant to the arginine structural analogue canavanine. In order to identify potential bottlenecks in the biosynthetic pathway that leads to this industrially important amino acid, relative metabolite abundances of biosynthetic intermediates were determined in comparison to the type strain ATCC 13032. An extract of U13C-labeled biomass was used as internal standard, to correct for different ionization efficiencies. Metabolites were identified using the ALLocator web platform.
