The World Health Organisation (WHO) has announced its first-ever list of antibiotic-resistant “priority pathogens”, a catalogue of 12 families of bacteria that posed threat to human health.
According to the organization, the list was drawn in a bid to guide and promote research and development of new antibiotics, as part of WHO’s efforts to address growing global resistance to antimicrobial medicines.
Marie-Paule Kieny, WHO’s Assistant Director-General for Health Systems and Innovation in a statement, said “this list is a new tool to ensure research and development respond to urgent public health needs.
“Antibiotic resistance is growing, and we are fast running out of treatment options. If we leave it to market forces alone, the new antibiotics we most urgently need are not going to be developed in time.”
The list highlights in particular the threat of “gram-negative” bacteria that were resistant to multiple antibiotics.
“These bacteria had built-in abilities to find new ways to resist treatment and could pass along genetic material that allowed other bacteria to become drug-resistant as well”. Kieny added.
The WHO list is divided into three categories according to the urgency of need for new antibiotics: critical, high and medium priority.
The Assistant Director General said “The most critical group of all includes multidrug resistant bacteria that pose a particular threat in hospitals, nursing homes and among patients whose care requires devices such as ventilators and blood catheters.
“They include Acinetobacter, Pseudomonas and various Enterobacteriaceae, including Klebsiella, E.coli, Serratia and Proteus.”
“They can cause severe and often deadly infections such as bloodstream infections and pneumonia”. She added. These bacteria have become resistant to a large number of antibiotics, including carbapenems and third generation cephalosporins, the best available antibiotics for treating multi-drug resistant bacteria.
Kieny said “G20 health experts will meet this week in Berlin to deliberate further.”
The list is intended to spur governments to put in place policies that incentivise basic science and advanced research and development by both publicly funded agencies and the private sector investing in new antibiotic discovery.
Recall in January this year the Nigeria Centre for Disease Control has brought experts together from various Ministries and Agencies, academia and the private sector to chart a path towards a National Action Plan to combat antimicrobial resistance in Nigeria.
Joshua Obasanya, director of Planning, Research & Statistics of the NCDC said “We at the NCDC hold ourselves extremely accountable for this coordination effort; our work is to ensure all relevant actors participate in this.
“We want to make sure that the One Health approach is evident as we combat AMR in Nigeria.” He said
While more research and development was vital, it could not solve the problem, the WHO official said.
To address resistance, there must be better prevention of infections and appropriate use of existing antibiotics in humans and animals, as well as rational use of new antibiotics.
Evelina Tacconelli, head of the Division of Infectious Diseases at the University of Tübingen and a major contributor to the development of the list says “New antibiotics targeting this priority list of pathogens will help to reduce deaths due to resistant infections around the world,”
“Waiting any longer will cause further public health problems and dramatically impact on patient care.” Tacconelli added.
