معرفی
Dirk Bumann is a Full Professor of Infection Biology at the Biozentrum, University of Basel, where he leads a research group focused on bacterial pathogenesis and antimicrobial resistance. His laboratory investigates the complex interactions between bacterial pathogens like Salmonella and Pseudomonas aeruginosa and host tissues, with particular emphasis on how nutrient availability in host environments affects bacterial behavior and antibiotic efficacy. As a director of the NCCR AntiResist initiative, he plays a key role in Switzerland's national effort to combat antimicrobial resistance through innovative research approaches.
Professor Bumann's research interests center on infection biology, particularly the metabolic adaptation of bacterial pathogens during infection. His team has made seminal discoveries regarding how host-imposed nutrient deprivation (particularly magnesium and iron limitation) creates environments where bacteria become more resilient to antibiotics, challenging previous assumptions about bacterial persisters. Using advanced techniques including single-cell analysis, whole-organ tomography, and mass spectrometry, his group examines bacterial behavior in physiologically relevant conditions that better mimic human infections than traditional laboratory methods.
Analysis of his recent publications reveals a consistent focus on host-pathogen metabolic interactions and their implications for antibiotic treatment failure. His 2025 Nature paper fundamentally challenges the persister hypothesis by demonstrating that nutrient starvation—not specialized bacterial subpopulations—is the primary reason for antibiotic treatment failures in Salmonella infections. This work highlights the critical importance of studying bacterial pathogens in conditions that accurately reflect the host environment.

Professor Bumann's research group includes several PhD students, postdoctoral fellows, and technical staff working collaboratively on various aspects of bacterial pathogenesis. His laboratory maintains strong collaborations with University Hospitals Basel and Zurich through the NCCR AntiResist initiative, extending their research from mouse models to human patient samples infected with Staphylococcus aureus, Pseudomonas aeruginosa, and E. coli. Current projects focus on developing more physiologically relevant methods for antibiotic testing and understanding how tissue compartmentalization affects bacterial persistence during chemotherapy.
