How fast antimicrobial susceptibility testing could impact sepsis management
27 Nov 2025Bloodstream infections (BSIs) remain a significant public health challenge. Today, antimicrobial susceptibility testing (AST) is the gold standard for guiding therapy in BSI management. However, conventional AST methods are often slow, taking days to deliver results. This delay forces clinicians to prescribe empiric, broad-spectrum antimicrobials, a practice that contributes to the overuse and misuse of antimicrobials – a leading driver of antimicrobial resistance.
In this article, bioMérieux delves into the benefits of fast AST and explores why it has the potential to bridge the critical gap in BSI and sepsis management.

Clinical MicrobiologyMicrobiology is the study of microorganisms including protists, prokaryotes, fungi, and, often, viruses. Microorganisms are a useful research tool as genetic vectors and, in immunology, for antibiotic susceptibility testing, cellular biology and genetics. Microorganisms commonly grow readily in incubators with microbial culture media; this can contain chromogenic supplements to differentiate between cell lines. Estimate your culture’s density of microorganisms with colony counters, or screen and select colonies for desirable clones with automated colony pickers. Additionally, equipment is available to monitor environments for the presence of microbes and identify with microbial identification instruments.
