- This approach could significantly lower the incidence of treatment failures.
Sydney, June 5 (NationPress) Australian researchers have made a significant breakthrough in addressing Staphylococcus aureus, widely recognized as golden staph, a superbug responsible for over a million fatalities globally each year.
This groundbreaking initiative, revealed by the Melbourne-based Peter Doherty Institute for Infection and Immunity (Doherty Institute) on Wednesday, showcases that real-time genome sequencing during severe infections empowers physicians to swiftly identify resistance mutations, tailor treatments, and mitigate the spread of antibiotic resistance, according to reports from Xinhua news agency.
Working alongside seven local hospitals, scientists at the Doherty Institute noted that conventional hospital laboratories typically identify bacteria using standard tests, which only reveal the species type, thus limiting insight into antibiotic resistance or genetic shifts.
In comparison, genome sequencing offers a detailed genetic profile, revealing mutations that may affect bacterial responses to treatment.
Historically, research on bacterial evolution was often conducted retrospectively, years after patients had completed their treatments. However, this innovative approach allows clinicians to observe bacterial changes in real-time, offering immediate, actionable insights for patient care, as outlined in a study published in Nature Communications.
By comparing golden staph samples from patients at the onset of infection and during treatment failure, researchers discovered that in one-third of the cases, the bacteria developed mutations rendering standard antibiotics ineffective, explained lead author Stefano Giulieri at the Doherty Institute and the University of Melbourne.
“In one instance, after successfully managing a golden staph infection, the patient returned to the hospital two months after discontinuing antibiotics,” Giulieri stated, highlighting that resistance surged eightyfold in that time. However, genomic insights enabled clinicians to successfully adapt treatment and eradicate the infection.
Following the findings, Victorian hospitals are set to launch the world's inaugural clinical genomic service for treatment-resistant cases, as stated in the release.
Point of View
It’s clear that the advancement of real-time genome sequencing represents a significant leap forward in our fight against antibiotic-resistant infections. This innovative approach not only enhances patient care but also establishes Australia as a leader in medical research. At NationPress, we believe that such breakthroughs will have a lasting impact on global health.
