21. Molecular and cellular mechanisms during adherence and cell signaling of pathogenic Neisseria to host cells
Abstract : The pathogenic members of the genus Neisseria include N. gonorrhoeae and N. meningitidis. Both organisms are obligate human pathogens that colonize mucosal surfaces. READ MORE

22. A study of bacterial adhesion on a single-cell level by means of force measuring optical tweezers and simulations
Abstract : The intriguing world of microbiology is nowadays accessible for detailed exploration at a single–molecular level. Optical tweezers are a novel instrument that allows for non–invasive manipulation of single cells by the sole use of laser light and operates on the nano– and micrometer scale which corresponds to the same length scale as living cells.

23. The interaction between the neuroretina and the retinal pigment epithelium : an electrophysiological study of the effects of possible messenger substances and their analogues
Abstract : The retinal pigment epithelium (RPE) is of great importance in photoreceptor homeostasis. The photoreceptors are highly specialized cells which cannot survive without the RPE. It has been postulated that messenger substances are involved in the interaction between the RPE and the inner retina. READ MORE

24. Competence pilus biogenesis in Streptococcus pneumoniae
Abstract : Horizontal gene transfer drives bacterial evolution and is crucial for the pathogenicity of many bacteria that can exchange genetic material through distinct mechanisms such as natural transformation. S. READ MORE

25. Genetic approaches towards understanding penumococcal virulence and biology
Abstract : Streptococcus pneumoniae, the pneumococcus, is a major human pathogen giving rise to death and illness worldwide every year. It causes a wide variety of diseases, from normally harmless infections such as otitis media to potentially life-threatening systemic diseases such as pneumonia, meningitis and sepsis. READ MORE
