Next Session: CLSI, EUCAST and Their Impact on Microbiology—Jan. 9, 2026, 1 p.m. ET

The main organizations for guidance for antimicrobial susceptibility testing are CLSI and EUCAST. This is because a lot of antibiotic development and clinical trials occur in Europe and the U.S. However, there are a few differences between the 2 agencies. Each agency has a specific approach to determining clinical breakpoints and how antimicrobial susceptibility and resistance are reported, resulting in different cutoffs. Please join us to discuss whether those differences have an impact on infectious disease guidelines, clinical practices and how antibiotics are prescribed.
