USCAST is part of a global network dedicated to fighting the rise of antibiotic resistance through scientific, educational, and policy-creating activities.

We recognize an increasing need to create a path to evaluate both new and old antibacterial agents in the current context of antibacterial resistance, extent of tissue penetration at the site of infection, and bacterial killing rate at that body site.

Our mission is to work with our global partners, establishing crucial standards for testing and interpreting the activity of antibacterial agents. The standards established by USCAST are intended to provide support for healthcare providers to use the safest and most effective antibacterial agents to save lives.

Unlike other STIC setting organizations, USCAST does not aim to provide comprehensive pathogen-drug breakpoint tables, but rather focuses the expertise of our membership on both generating new evidence and interpreting imperfect existing data to address the most challenging breakpoint controversies.
