Antimicrobial resistance is a growing threat to effective treatment of infection. The Montana Public Health Laboratory provides the following information to assist providers, pharmacies, and laboratories in their efforts to manage antibiotic use. To align Montana’s program more closely with national infection control initiatives, the Montana Public Health Laboratory will update the antimicrobial susceptibility data collected from clinical sites, beginning with data generated in 2012.

Multi-level Antimicrobial Susceptibility Testing Resources (MASTER) (CDC)
MASTER provides information on antimicrobial susceptibility testing issues related to clinical microbiology laboratory practice. It contains a series of case studies that address contemporary antimicrobial susceptibility testing issues.
AR Susceptibility Testing Training Module (CDC)
The e-leaning module “Modes & Mechanisms of antimicrobial agents” provides basic information on mechanisms of antimicrobial resistance.
