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:Brucella melitensis and Brucella canis differ by ~75 genes yet B. melitensis is highly virulent for humans while B. canis is considered rarely pathogenic. No identified bacterial factors or mechanisms account for this difference in virulence. To identify functional differences of these two bacteria, gene transcription was examined during infection of murine macrophages and compared to bacteria grown in broth. Our analysis identified transcriptional differences in macrophage infection between B. melitensis and B. canis genes involved in iron transport. Increased transcription of the TonB, enterobactin, and ferric anguibactin transport systems were observed in B. canis but not B. melitensis during infection of macrophages. Therefore, iron appears as an important requirement during the first 24h of infection by B. canis but not for B. melitensis and provides strategies for controlling these pathogens.

Project description:A lot of attempts have been made to understand the immunopathological mechanisms of Brucella canis infection because of the importance of the disease in both public and clinical aspects. However, previous mechanisms are not still revealed. Therefore, in vitro models, which mimic to in vivo infection route using a canine epithelial cell, D17 cell, and a canine macrophage, DH82 cell, was used to solve the clues by analysis of transcriptomes in the cells. In this study, a co-culture model was constructed using the two cells, D17 and DH82 cell lines with trans-well plate. Also, a single cell culture system using DH82 was established. After stimulation of the cells in two different systems with B. canis, gene expressions in the macrophages of the two different system were analyzed by RNA-sequencing.
