Transcriptome analysis of M. catarrhalis RH4 predicted coding sequences and clustered regularly interspaced short palindromic repeats (CRISPRs) regions. The results described in this study are further discussed in De Vries, S.P.W., van Hijum, S.A.F.T., Schueler, W., Riesbeck, K., Hays, J.P., Hermans...
ORGANISM(S): Moraxella catarrhalis RH4 
Iron-sequestration by the human host is a first line defense against respiratory pathogens like Moraxella catarrhalis, which consequently experiences a period of iron-starvation during colonization and infection. We determined the genetic requirements for M. catarrhalis growth during iron-starvation...

Infection of the human host by Streptococcus pneumoniae begins with colonization of the nasopharynx, which is mediated by adherence of bacteria to respiratory epithelium. Several studies have indicated an important role for the pneumococcal capsule in this process. Here, we used microarrays to chara...

Several genes involved in nitrogen metabolism are known to contribute to the virulence of pathogenic bacteria. Here, we studied the function of the nitrogen regulatory protein GlnR in the Gram-positive human pathogen Streptococcus pneumoniae. We demonstrate that GlnR mediates transcriptional repress...

This microarray experiment is part of a study addressing the importance of glutamine metabolism in Streptococcus pneumoniae for the virulence of this bacterium. To be able to gain more insight into the phenotype of a double mutant of glnA (TIGR 4 locus tag SP0502, encoding glutamine synthetase) and ...
