The Priority Pathogens List was published by WHO in a bid to promote. research and development (R&D) of new antibiotics, as part of WHO’s efforts to address growing global resistance to antimicrobial medicines. The list highlights in particular the threat of gram-negative bacteria that are resistant to multiple antibiotics. The WHO list is divided into three categories according to the urgency of need for new antibiotics: critical, high and medium priority.
