The American Society for Microbiology (ASM) is leveraging its new phage therapy coordination efforts to connect researchers and clinicians, standardize approaches, and explore how bacteriophages could complement antibiotics in the fight against antimicrobial resistance. Colleen Kraft, MD, offers some insights on the organization's plans to help grow this medical modality.
A new multiplex blood-screening assay is streamlining transfusion safety by enabling simultaneous detection and discrimination of HIV, HBV, HCV, and hepatitis E in a single test, helping laboratories improve efficiency, reduce turnaround times, and strengthen blood supply resilience amid ongoing donation and staffing shortages. Nico Michel, PhD, of Roche Diagnostics, offers insights on this diagnostic.
A once-weekly oral HIV treatment combining islatravir and lenacapavir achieved its primary efficacy endpoint in 2 phase 3 trials, bringing the investigational regimen closer to becoming the first approved long-acting oral HIV therapy.
A novel antimicrobial susceptibility testing platform, ATB Finder, is designed to improve treatment outcomes by evaluating antibiotics under conditions that closely mirror the infection site and microbial communities found in patients. George Tetz, MD, PhD, offers insights on this platform.
The FDA's accelerated approval of this therapy provides the first approved treatment option for chronic hepatitis delta in the US. Anu Osinusi, MD, discusses how this targeted therapy is designed to slow disease progression and improve patient outcomes.
