      Article
      Accés obert
      Simkania negevensis is an obligate intracellular bacterium grouped into the order Chlamydiales. This new amoeba-resistant intracellular bacterium might represent a novel etiologic agent of bronchiolitis and community-acquired ...

    • Satellites in the prokaryote world 

      Subirana Torrent, Juan A.; Messeguer Peypoch, Xavier (2019-09-18)
      Article
      Accés obert
      Background Satellites or tandem repeats are very abundant in many eukaryotic genomes. Occasionally they have been reported to be present in some prokaryotes, but to our knowledge there is no general comparative study ...

    • Smart sensing fabrics for live bacteria detection 

      Ferrer-Vilanova, Amparo; Ivanova, Kristina Dimitrova; Diaz-Gonzalez, Maria; Alonso, Yasmine; Guirado, Gonzalo; Tzanov, Tzanko; Muños-Berbel, Xavier (Multidisciplinary Digital Publishing Institute (MDPI), 2018-11-27)
      Article
      Accés obert
      A smart textile for live bacteria detection of antimicrobial hospital tissues is here proposed. The capacity to detect viable bacteria is based on the use of Prussian Blue (PB) as electrochromic compound, with a clear ...
