Comparative transcriptome analysis of Brucella melitensis 16M and its hfq mutant under acidified minimum medium (GEM4.0) conditions

ABSTRACT: Hfq is a bacterial Sm-like protein which serves as a post-transcriptional regulator of global gene expression. It has been shown to be involved in a wide range of cellular processes and pathways. To characterize the regulation roles of Hfq in Brucella melitensis, the in vitro hfq induction conditions simulating intracellular environments were firstly defined, and then, the transcriptome of the hfq mutant was compared to that of the wild type strain. Comparative transcriptome analysis showed that a total of 359 genes showed a>2.0-fold change in transcript abundance in Δhfq when compared to that in 16M.

PrlR regulon in Brucella melitensis 16M

Project description:Investigation of whole genome gene expression level changes in a Brucella melitensis delta prlr mutant compared to the wild type strain. The mutants analyzed in this study are further described in A. Mirabella, R-M Yanez, R.M. Delrue, S. Uzureau, M.S. Zygmunt, A. Cloeckaert, X. De Bolle, J.J. Letesson (2012). The two component system PrlS/PrlR of Brucella melitensis is required for persistence in mice and appears to respond to ionic strength. Microbiology A six chip study using total RNA recovered from three separate wild-type cultures of Brucella melitensis 16M and three separate cultures of a prlR mutant strain. Each chip measures the expression level of 3,198 genes from Brucella melitensis 16M with nineteen 60 mer probe pairs (PM/MM) per gene, with three-fold technical redundancy.

Expression response of Brucella melitensis strain 16M (ATCC23456) to erythritol

Project description:The four-carbon sugar erythritol is an important component of B. melitensis pathogenesis. To determine the transcriptional response to erythritol, B. melitensis strain 16M was grown in the presence of either glucose or erythritol as a sole carbon source. Two control samples (glucose) and two experimental samples (erythritol) were analyzed on Nimblegen B. melitensis microarray chips.
