An estimated five to ten percent of blindness worldwide is caused by the rare inflammatory eye disease uveitis. Posterior uveitis in particular is often associated with severe disease progression and the need for immunosuppressive therapy. In posterior uveitis, inflammation occurs in the retina and in the underlying choroid that supplies it with nutrients. Researchers have tested color-coded fundus autofluorescence as a supportive novel diagnostic method. Fluorescence of the retina can be used to infer the uveitis subtype. This is an essential prerequisite for accurate diagnosis and treatment of the disease.

In Gram-negative bacteria, which include some of the most devastating human pathogens, just two mechanisms for the export of polysaccharides have been identified so far. Now a research team has identified an entirely novel third mechanism for how polysaccharides are exported. These findings pave the way toward a complete understanding of the mechanisms that mediate the protection, motility and interaction of many bacterial pathogens.
