Limiting the Spread

Tracking Resistance

Improving Stewardship

Developing New Solutions


The differences in activity among new β-lactam/β-lactamase inhibitor combinations creates challenges for many clinicians and it will become increasingly important for microbiology laboratories to be able to produce meaningful results that will aid in the appropriate choice of these new agents. However, microbiology laboratories have few options available to determine the susceptibility of organisms to these novel antimicrobial agents as few of them are yet available on commercial AST platforms.1 Disk diffusion is the only option for testing some of these new drugs, but disks are often difficult to get. Clinical microbiology laboratories face a dilemma when it comes to providing information about the susceptibility or resistance of bacterial isolates to ceftazidime/avibactam and ceftolozane/tazobactam.

Only when healthcare providers are able to identify whether an infection is present and if it is drug resistant in minutes rather than days, will we be able to move beyond empiric therapy. On-demand molecular diagnostics have the potential to do just that. Innovative new, on-demand diagnostics will help prevent the inappropriate use and overuse of antimicrobials and preserve our antibiotic weapons now and in the future.


If the world is serious about tackling the threat of drug-resistant infections, we need to fully embrace the step-change in technology that rapid point-of-care diagnostics represent.”
