These reports are aggregated from clinical isolates submitted to the UCSF Clinical Microbiology Laboratory from adult patients at the UCSF Parnassus, Mission Bay, and Mt. Zion locations and are meant to guide clinicians in selecting empiric therapy. Patient characteristics must be incorporated in determining risks and therapy should be modified based on susceptibility testing results when available. Breakpoints for susceptibility are via CLSI guidelines. This page was last updated 6/23/23.
