The eight year old, female dromedary was integrated into a new herd in August 2014 for breeding purposes. At this time, several animals in the herd already suffered from nodes in the skin and in July 201, the newly introduced dromedary also developed multiple subcutaneous nodes and a large abscess on the lower abdomen. When returning home in early August 201, the dromedary was euthanised for reasons of animal welfare and due to detection of C. pseudotuberculosis and unsuccessful antibiotic treatment of the abscess and arthritis. Post mortem examination revealed multiple subcutaneous nodes and abscesses in the lung which were surrounded by a fibrous capsule and filled with yellowish, creamy pus. Histopathological examination showed a granulomatous inflammation. Bacteriological examination found strong growth of corynebacteria accompanied by modest growth of staphylococci and these could be clearly identified as C. pseudotuberculosis and Staphylococcus aureus using MALDI-TOF MS and FT-IR analyses. Serological investigations using an in-lab and a commercially available C. pseudotuberculosis ELISA yielded strong positive reactions. This case of severe caseous lymphadenitis in a dromedary clearly shows the high risk of introduction of infections if attention is not paid to individual and herd health status.  a0005-9366
