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.
Project description:We sequenced the mRNA of Brucella melitensis 16M and otpR mutant under acid stress to identify genes that were regulated by regulator OtpR.
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.
