MOC - AI in Microbiology
Artificial intelligence and machine learning applied to microbes — structure prediction, diagnostics, resistance, discovery, and surveillance.

Overview
AI in microbiology learns patterns from large biological datasets — sequences, images, spectra, electronic records — to predict structures, identify organisms, infer resistance, design molecules, and detect outbreaks. It sits on top of bioinformatics outputs, and never replaces wet-lab confirmation (Antimicrobial Susceptibility Testing, culture).

Core Concepts to Internalize
- Data quality dominates model choice. Label noise from imperfect AST ceilings performance.
- Population structure is the microbiology-specific confounder — models learn lineages, not mechanisms (Population Structure Confounding in Microbial ML).
- Calibration and error types matter more than AUC — very major errors are the currency of clinical acceptance.
- Explainability — clinicians act on reasons, not scores.
- Human-in-the-loop — AI proposes, laboratory confirms, clinician decides.
- Drift — pathogens and breakpoints change; models decay silently.
- MIC ≠ persistence — tolerance phenotypes need different labels and models.

Research Questions
- When is genomic ML accurate enough to replace phenotypic AST, and for which drug–bug pairs?
- How do we detect model failure on novel plasmids or unseen species?
- What governance is required before AI reads clinical Gram stains autonomously?
- Can protein language models prioritize truly novel resistance determinants prospectively?
- Do AI stewardship tools change patient outcomes, not just prescribing metrics?
