As a licensed DVM, Prof. Menge possesses broad knowledge and expertise in surveillance, diagnosis, control and eradication of epizootic diseases in accordance with rules laid down in national and international animal health legislation. He has particular expertise in the analysis of bacterial host-interactions at the intestinal mucosal surface of livestock. Using in vitro culture systems and experimental infection studies in the target species his group elucidated the mechanisms by which enterohaemorrhagic Escherichia coli (EHEC) manipulates its host´s immune system. He also has substantial expertise in clinical immunology and the immunobiology of other bacterial pathogens, e.g., tuberculous and non-tuberculous Mycobacteria and Coxiella, viruses and parasites in large and companion animal species. His recent research focusses on drivers and dynamics of host-to-host and cross-species transmission of bacteria exhibiting antimicrobial resistance (AMR), also deploying innovative sampling strategies from a One Health perspective.
