Specialty Content

Medical Microbiology specialty

Microbiology covers bacteriology, antimicrobial susceptibility, blood culture processing, infection prevention, and molecular diagnostics.

Where the content lives

• Interview page — /microbiology-interviews — Band 2 through Band 8 questions
• Common technical questions — /biomedical-sciences/common-technical-questions-microbiology-interview-uk
• Embedded guides — Gram staining, culture media selection, antimicrobial susceptibility testing (AST), EUCAST breakpoints, blood culture processing, molecular diagnostics, specimen rejection criteria
• Microbiology Virtual Lab — /virtual-laboratory → Microbiology — organism identification, sensitivity testing, reporting workflow
• Result Interpretation — open /result-interpretation and click the Microbiology card — sensitivity panels, organism ID, clinical correlation
• Specialist Portfolio (Medical Microbiology) — /portfolio → Specialist Portfolio → Medical Microbiology

EUCAST 2026 v16.0

EUCAST clinical breakpoints v16.0 are valid from 1 January 2026. All susceptibility-testing content references this version. Older content has been updated.

Key competencies covered

• Gram staining and microscopy
• Culture media selection (chromogenic, selective, enrichment)
• AST methodologies — disc diffusion, MIC by gradient or broth microdilution
• EUCAST 2026 v16.0 breakpoint interpretation
• Blood culture processing — flagging, subculture, identification
• Molecular diagnostics — PCR, syndromic panels
• Infection prevention and control — current UKHSA guidance
• Mycology, parasitology, mycobacteriology (specialty areas)
• BSAC / EUCAST methodology differences

Bands progression

• Band 5 (£32,073-£39,043) — qualified BMS plating, reading cultures, basic ID, supervised sensitivity reporting
• Band 6 (£39,959-£48,117) — specialist AST sign-off, complex case interpretation, training, often requires the Specialist Portfolio in Medical Microbiology
• Band 7 (£49,387-£56,515) — section lead, on-call clinical advice, governance, MDT participation

Standards alignment

• EUCAST 2026 v16.0 — clinical breakpoints (from 1 Jan 2026)
• BSAC — UK methodology reference
• UKHSA (UK Health Security Agency — successor to PHE) — guidance and reference labs
• ISO 15189:2022 quality framework
• UK NEQAS Microbiology
• NICE guidance on antimicrobial stewardship

Common interview question themes (Band 5-7)

• "Walk me through your blood culture workflow"
• "How would you handle a positive blood culture out of hours?"
• "How do you interpret a multi-resistant Gram-negative AST result?"
• "Describe how you would respond to a sentinel organism (e.g. CPE) finding"
• "How does EUCAST v16.0 differ from the previous version on key drugs?"
