The Rise And Rise Of Antimicrobial Resistance In Gram-Negative Bacteria

Antimicrobial resistance is a major threat to the delivery of effective care and already causes 700 000 excess deaths per year worldwide. International consensus on action to combat antimicrobial resistance was reached in 2015. Australia is implementing a national strategy. The clinical consequences of antimicrobial resistance are seen most acutely in multi-drug resistant Gram-negative bacterial infections, where they cause increased mortality and morbidity and threaten the delivery of once routine medical care. The solution to antimicrobial resistance is complex and multifaceted. Antimicrobial stewardship, that is optimising the use of the antibiotics we currently have, is the most rapidly deployable mitigation. Several novel antibiotics with activity against a range of drug-resistant bacteria are now available clinically, leading to hope that innovative solutions will reduce the impact of resistance. It is critical that these new drugs are protected from inappropriate use.
