When it comes to complex topics in the field of health and risk communication, experts are of high importance for the credibility of a news media report. This paper examines the use of experts and their roles in the news media coverage of multi-resistant pathogens by means of a quantitative content analysis of German print and online news. A cluster analysis of the expert statements identifies three different statement frames describing different expert roles. The results show manifest patterns of selected expert sources, which points to professionalized mechanisms of selecting expert sources for news media reports.
