    Department of Internal Medicine, Medical University of Graz, Graz, Austria
    N Engl J Med 355:2418-26. 2006
    ..Antibiotic-associated hemorrhagic colitis is a distinct form of antibiotic-associated colitis in which Clostridium difficile is absent. Although the cause is not known, previous reports have suggested a role of Klebsiella oxytoca...

    Christoph Hogenauer
    Department of Internal Medicine, Medical University of Graz, Austria
    Eur J Gastroenterol Hepatol 17:371-6. 2005
    ..We therefore compared the value of DNA testing for this variant (DNA test) with the lactose hydrogen breath test (H2 test), which is the clinical standard for the diagnosis of lactase non-persistence...

    Martina M Joainig
    Institute of Molecular Biosciences, University of Graz, Graz, Austria

  4. doi Role of Klebsiella oxytoca in antibiotic-associated diarrhea
    Ines Zollner-Schwetz
    Section of Infectious Diseases, Division of Pulmonology, Department of Internal Medicine, Medical University of Graz, Graz, Austria
    Clin Infect Dis 47:e74-8. 2008
    ..Because it is unclear whether K. oxytoca also causes nonhemorrhagic antibiotic-associated diarrhea, our study investigated a possible association between K. oxytoca and that disorder...
  5. pmc Alterations in the colonic microbiota in response to osmotic diarrhea
    Gregor Gorkiewicz
    Institute of Pathology, Medical University of Graz, Graz, Austria
    PLoS ONE 8:e55817. 2013
