Tuberculosis stands as one of the most lethal infectious diseases worldwide. A significant challenge in combatting tuberculosis lies in the emergence of antibiotic resistance triggered by genetic alterations, commonly known as mutations. These mutations can diminish the responsiveness to antibiotics,…

At Leiden University, there is plenty of experimentation with good ideas to make education even better.
