What you will be able to do

  • Describe the structure of bacterial, archaeal and eukaryotic microbial cells and how they are classified
  • Explain bacterial growth and calculate generation times, population sizes and colony counts
  • Distinguish sterilisation, disinfection and antisepsis and explain how common control methods work
  • Summarise how microbes make energy: fermentation, aerobic and anaerobic respiration, and photosynthesis
  • Explain DNA replication, transcription, translation and the three routes of horizontal gene transfer
  • Describe virus structure and the lytic and lysogenic replication cycles
  • Outline innate and adaptive immune defences and how vaccination builds memory
  • Use the vocabulary of virulence, transmission and epidemiology, and explain antimicrobial action and resistance as concepts

Topics

  • Microbial cell structure and classification
    How bacteria, archaea and eukaryotic microbes are built, how they are grouped into three domains, and why the Gram stain works.
  • Microbial growth and control
    The bacterial growth curve, doubling calculations, counting colonies after dilution, and how heat and chemicals control microbes.
  • Microbial metabolism
    How microbes capture energy with glycolysis, fermentation and respiration, and how they are classed by energy and carbon source.
  • Microbial genetics
    DNA replication, transcription and translation in bacteria, and how genes move between cells by transformation, transduction and conjugation.
  • Viruses
    What viruses are made of, how they replicate, and the difference between lytic and lysogenic cycles.
  • The immune system
    Innate and adaptive defences, the cells and antibodies involved, and how immune memory works.
  • Pathogenesis and infection
    How microbes cause disease: virulence, toxins, stages of infection, routes of transmission and the language of epidemiology.
  • Infection control and antimicrobial concepts
    How infection control breaks the chain of transmission, how antimicrobials target microbes, and how resistance arises, as concepts only.
