Unit 3: Practical Microbiology and Infectious Diseases deck, 35 slides Unit 3 in the spec (A1–A3, B1–B4, C1–C4, D1–D2).
What’s in it:

Introduction (4 slides): the box key with a safety reminder, the four learning aims, and the PSAB with what each grade needs.
A: Microorganisms (7 slides):
A drawn bacterial cell with Gram positive vs negative.
A native growth curve (lag, log, stationary, death).
Protists by movement, using the spec’s examples, and fungi.
Viruses with lytic vs lysogenic cycles, and prions.
Virulence mechanisms for bacteria, eukaryotes and viruses.
Classification by shape, oxygen needs and a Baltimore classes I–VII table.
B: Infectious diseases (8 slides):
Direct and indirect transmission with the six-link chain of infection.
Two tables covering all 16 diseases in the spec (agent, spread and signs).
Five vaccine types with examples, and treatments by pathogen type, including malaria stages.
Antibiotic resistance as a selection flow, with MDR gonorrhoea and sepsis.
Herd immunity, antigenic variation and vaccine uptake.
C: Lab techniques (7 slides):
Hazard groups and containment levels, COSHH and autoclaving.
Aseptic technique.
Staining and slide preparation.
Colony morphology, broth growth types and magnification.
Selective media (MacConkey, mannitol salt, blood, potato dextrose) and culture methods.
Viable vs total counts, with advanced techniques.
D: Antimicrobials (4 slides): a susceptibility testing procedure, a native zone-diameter chart with statistics and error bars, the limitations listed in the spec (old discs, agar depth, non-confluent lawns), critical thinking, and an Evaluate model.
Review (4 slides): an assignment plan, the criteria at a glance, a confidence tracker and a “Well done” slide.

BTEC Medical Science AAQ Unit 3 | Practical Microbiology & Infectious Diseases Bundle

**SEO TITLE** BTEC Medical Science AAQ Unit 3 | Practical Microbiology & Infectious Diseases Bundle **TES DESCRIPTION** A three-resource bundle for the Pearson Level 3 Alternative Academic Qualification BTEC National in Medical Science (Extended Certificate), Unit 3: Practical Microbiology and Infectious Diseases. Supports post-16 teaching, practical understanding, independent study and preparation for the internally assessed Pearson Set Assignment Brief (PSAB). **WHAT'S INCLUDED** **1. 35-SLIDE EDITABLE POWERPOINT** Covers all four learning aims: - Microorganisms: bacteria, viruses, fungi, protists, prions, cell structure, growth curves, virulence and classification. - Infectious diseases: transmission, chain of infection, signs and symptoms, vaccines, treatments, antimicrobial resistance and herd immunity. - Laboratory techniques: hazard groups, containment, COSHH, aseptic technique, microscopy, staining, culture media and microbial analysis. - Antimicrobials: susceptibility testing, zones of inhibition, data interpretation, limitations and evaluation. Includes diagrams, practical guidance, charts, assignment planning and review. **2. 20 VISUAL REVISION MATS** Visual summaries to reinforce key concepts, scientific vocabulary and retrieval practice. **3. 44-PAGE EDITABLE STUDENT WORKBOOK** Structured activities and practical guidance across all four aims, with assessment support, worked examples, common-mistake prompts and assessed-task pages. Adaptable to your learners and centre procedures. **WHY CHOOSE THIS BUNDLE?** Teach with the PowerPoint, consolidate with the mats and support practical and assessment preparation through the workbook. **SEO KEYWORDS** BTEC Medical Science AAQ; Pearson Level 3 Medical Science; BTEC National; Unit 3 Practical Microbiology; infectious diseases; microorganisms; bacteria; viruses; fungi; protists; prions; virulence; chain of infection; antimicrobial resistance; aseptic technique; microscopy; staining; culture media; microbial growth; antimicrobial susceptibility; PSAB; practical science; visual revision mats; editable workbook; teaching PowerPoint. **COPYRIGHT & DISCLAIMER** © 2026 Coffee Owed.
