Clostridium difficile wird meist als nosokomialer Erreger, der mit Diarrhö oder pseudomembranöser Colitis einhergeht, angesehen. Im Jahr 2007 wurden von Spitälern in Österreich 2.761 Clostridium-difficile-Infektionen (277 davon mit tödlichem Ausgang) gemeldet, im Vergleich dazu waren im Jahr 2003 nur 777 Fälle (53 davon mit tödlichem Ausgang) registriert(More)
Recently we have shown that a low (R(low)) and a high laboratory passage (R(high)) of the poultry pathogen Mycoplasma gallisepticum prototype strain R differ markedly in their capability to invade non-phagocytic eukaryotic cells. In the present study the infection traits of these two mycoplasma passages were compared in an in vivo setting. After aerosol(More)
We report an outbreak of listeriosis in Austria and Germany due to the consumption of Quargel cheese produced by an Austrian manufacturer. At the time of writing this report, the outbreak was known to account for 14 outbreak cases in 2009, including four cases with lethal outcome. On 23 January 2010, the cheese product was voluntarily withdrawn from the(More)
Mycoplasma gallisepticum is an important avian pathogen that commonly induces chronic respiratory disease in chicken. To better understand the mycoplasma factors involved in host colonization, chickens were infected via aerosol with two hemadsorption-negative (HA(-)) mutants, mHAD3 and RCL2, that were derived from a low passage of the pathogenic strain R(More)
Mycoplasma gallisepticum is a flask-shaped organism that commonly induces chronic respiratory disease in chickens and infectious sinusitis in turkeys. Phenotypic switching in M. gallisepticum hemadsorption (HA) was found to correlate with phase variation of the GapA cytadhesin concurrently with that of the CrmA protein, which exhibits cytadhesin-related(More)
We previously reported an outbreak of listeriosis in Austria and Germany due to consumption of Quargel cheese. It comprised 14 cases (including five fatalities) infected by a serotype 1/2a Listeria monocytogenes (clone 1), with onset of illness from June 2009 to January 2010. A second strain of L. monocytogenes serotype 1/2a (clone 2) spread by this product(More)
An investigation of dangerous bacterial pathogens was conducted to determine the usefulness of automated rRNA operon ribotyping (RiboPrinter system) to identify species. A total of 26 isolates comprising Bacillus anthracis, Brucella spp., Burkholderia mallei, Francisella tularensis, and Yersinia pestis were tested using restriction endonucleases EcoRI,(More)
Im September 2008 erfuhr die Österreichische Agentur für Gesundheit und Ernährungssicherheit (AGES) von einem Ausbruch infektiöser Gastroenteritis; die Blutkultur eines 71-jährigen Hospitalisierten hatte Listeria monocytogenes erbracht. Sieben von 19 Teilnehmern eines Tagesausfluges nach Bratislava stellten Stuhlproben zur Verfügung; aus drei Proben konnte(More)
In Austria, a total of 606 food borne outbreaks, affecting 1,910 people altogether (including 368 hospitalized patients and 1 fatal outcome) were documented in 2005. Salmonella spp. and Campylobacter spp. accounted for 99% of all reported outbreaks. Fortysix (8%) of the 606 outbreaks were acquired abroad. Bacteria caused all but one of the 560 domestically(More)
