Antimicrobial resistance research team

The Antimicrobial resistant (AMR) research team combats global microbial resistance by understanding mechanisms, investigating contributing factors, and developing strategies. Microorganisms evolving to resist drugs, including bacteria, viruses, fungi, and parasites, complicate infections and increase spread. The interdisciplinary team collaborates in microbiology, molecular biology, epidemiology, and clinical medicine, conducting extensive laboratory and field studies to identify new resistant strains, analyze mechanisms, and evaluate antimicrobial agents. They pinpoint risk factors such as inappropriate antibiotic use, inadequate sanitation, and global travel, striving to contribute significantly to the global fight against AMR. Their vital work aims to preserve antimicrobial effectiveness, ensuring the success of modern medicine.
