While M100 covers common pathogens like E. coli or S. aureus, M45 focuses on the "difficult" ones—organisms that are either rarely isolated or have very specific, "fastidious" growth requirements. Without standardized guidance, labs might struggle to provide accurate susceptibility results, which are vital for clinicians treating rare but serious infections. What’s Inside the Latest Edition?
