1. Identification of new virulence factors in Francisella tularensis
Abstract : Francisella tularensis, the causative agent of tularemia, is a highly virulent bacterium with an infection dose of less than ten bacteria. The ability of a pathogen to cause infection relies on different virulence mechanisms, but in Francisella tularensis relatively few virulence factors are known. Two F. READ MORE

2. CopA and CopT: The Perfect RNA Couple
Abstract : Antisense RNAs regulate gene expression in many bacterial systems. The best characterized examples are from prokaryotic accessory elements such as phages, plasmids and transposons. Many of these antisense RNAs have been identified as plasmid copy number regulators where they regulate the replication frequency of the plasmid by negative feedback. READ MORE

3. Small RNAs, Big Consequences : Post-transcriptional Regulation and Adaptive Immunity in Bacteria
Abstract : It is nowadays widely accepted that non-coding RNAs play important roles in post-transcriptional regulation of genes in all kingdoms of life. In bacteria, the largest group of RNA regulators are the small RNAs (sRNAs). READ MORE

4. Multiple regulatory inputs for hierarchical control of phenol catabolism by Pseudomonas putida
Abstract : Metabolically versatile bacteria have evolved diverse strategies to adapt to different environmental niches and respond to fluctuating physico-chemical parameters. In order to survive in soil and water habitats, they employ specific and global regulatory circuits to integrate external and internal signals to counteract stress and optimise their energy status.

5. Hfq- and sRNA-mediated regulation in Neisseria meningitidis
Abstract : Neisseria meningitidis, also known as the meningococcus, is a human-specific pathogen that commonly colonises the nasopharynx without causing disease. For reasons unknown, N. meningitidis can traverse the nasopharyngeal epithelium and enter the bloodstream, causing invasive meningococcal disease manifesting in septicaemia and/or meningitis.
