It is the distance between finding a promising antibacterial, developing it for the bacteria most in need of treatment, securing investment, and making it reliably available for appropriate use. WHO identifies a critical research-and-development gap for antibacterials targeting gram-negative carbapenem-resistant bacteria; funding, registration, supply and stewardship all shape whether future treatments can close it.
What does “the antibiotic gap” mean?
It describes several connected problems, not one missing drug. A candidate may be scientifically promising but aimed at a lower-priority need, fail to attract the resources needed for development, or reach only a limited number of countries. Even after registration, supply interruptions can keep a medicine from patients. These are distinct stages: progress in discovery does not guarantee progress through development, registration, supply and appropriate use.

WHO’s World Antimicrobial Awareness Week factsheet describes a critical R&D gap for antibacterials targeting gram-negative carbapenem-resistant bacteria. WHO also describes annual reviews of preclinical and clinical antibacterial pipelines against its priority pathogens list. The priority-pathogen framing matters: the question is not simply whether research is happening, but whether it is addressing bacteria for which new options are especially needed.

A pipeline can contain candidates without adequately addressing a particular threat. WHO’s framing points to gram-negative carbapenem-resistant bacteria as an area of critical R&D gap, making scientific fit an essential measure of progress alongside the existence of research projects or products in development.
#1 Best Overall
A National Academies chapter, attributing its assessment to the 2023 WHO pipeline review and the Global AMR R&D Hub, quotes the review’s conclusion: “a glaring insufficiency in novel approaches in the R&D pipeline to effectively combat the increasing emergence and spread of antimicrobial resistance”. The statement describes a shortage of novel approaches; it should not be read as a count of particular drugs or as evidence that any one candidate will succeed.
Why is it difficult to finance antibiotic development?
Scientific need and commercial incentives do not necessarily line up. Health Canada’s record of a meeting on antimicrobial resistance describes the antibiotic market as subject to market failure and discusses both “push” and “pull” incentives. Push support helps fund research and development; pull incentives are intended to reward or encourage successful development. These approaches address different points in the development challenge, but neither alone guarantees that a treatment will reach every country where it is needed.
Rank #2
The OECD identifies CARB-X as a funder of early development for antibiotics, diagnostics and related products. That role illustrates how funding can support work before a medicine is ready for routine use. It does not, by itself, establish that a funded candidate will complete clinical development, be registered broadly or have a dependable commercial supply.
Why doesn’t approval automatically mean access?
Registration and supply are separate hurdles. Health Canada’s meeting record notes concerns that new antibiotics may be registered in only a few countries, while shortages and supply-chain interruptions can disrupt access. A treatment’s existence or authorization in one market therefore does not establish dependable availability elsewhere.
Rank #3
The OECD also reports that some older antibiotics remain clinically useful but are not widely available because they were never introduced in some markets or were later withdrawn. The access gap can involve established medicines as well as new candidates: maintaining or restoring availability may matter alongside developing something novel.

Availability needs to be paired with stewardship: policies and practices that support responsible antibiotic use. The OECD treats stewardship as part of the response to resistance alongside development and access. In practical terms, filling the gap is not simply a matter of making more antibiotics available; appropriate use is part of the same public-health problem.
What does the 2008 article “Filling the antibiotic gap” refer to?
The exact-title Chemistry World article by John Bonner was published on 19 September 2008. Its subtitle says that “Two new targets offer new lines of attack in the battle against drug-resistant strains of bacteria.” The available article record does not identify those targets or provide the article’s full text, so their names cannot be established here. That 2008 headline is historical context, not evidence of the current antibacterial pipeline or the status of those targets today.
