Determining which microbial taxa are out there, where they live, and what they are doing is a driving approach in marine microbial ecology. The importance of these questions is underlined by concerted, large-scale, and global ocean sampling initiatives, for example the International Census of Marine Microbes, Ocean Sampling Day, or Tara Oceans. Given decades of effort, we know that the large majority of marine Bacteria and Archaea belong to about a dozen phyla. In addition to the classically culturable Bacteria and Archaea, at least 50 "clades," at different taxonomic depths, exist...

INTRODUCTION: Haemodialysis is one of the treatment modalities for patients suffering from end stage renal disease (ESRD). Dialysis patients are exposed to large volumes of water for production of dialysis fluids. Treated water and dialysate come in direct contact with the patient's bloodstream. Such patients suffer from abnormalities of the immune system, making them more susceptible to infections. Microbial contamination of the treated water and dialysate can lead to biofilm formation and release of endotoxins in Haemodialysis system...
