Description - summary of the module content

Module description

The discovery of antibiotics has had an unprecedented impact on medicine. However, the subsequent overuse of antibiotics has led to the rise of antimicrobial resistance (AMR). In this module you will learn about AMR mechanisms, how they spread within and between bacterial species, and alternative strategies that have been or are being developed to fight infections caused by multi-drug resistant bacterial pathogens. This module will integrate knowledge on molecular microbiological processes with ideas and concepts from evolutionary biology.

Module aims - intentions of the module

The module will integrate molecular and evolutionary microbiology concepts to understand the problem of AMR and the need for new antimicrobial therapies. The module will discuss and critically evaluate the relevant literature and the latest developments in antimicrobial research. You will critically evaluate existing antimicrobial therapies and those currently under development, by studying their scientific basis and their potential to be ‘evolution-proof’. The module will assess the pros and cons of different antimicrobials, and how the context of a pathogen infection matters for the success of a therapy.

The content of the module is inspired by, and will inspire, current and future research on the development of new antimicrobials, including CRISPR-Cas based antimicrobials and bacteriophage therapy.

Syllabus plan

Syllabus plan

Whilst the module’s precise content may vary from year to year, it is envisaged that the syllabus will cover some or all of the following topics:

  • History of antibiotic discovery and use
  • Antibiotics classification and mechanisms of action
  • Ecological consequences of antibiotic use
  • Evolution, mechanisms and spread of AMR in bacteria
  • Antimicrobial strategies that reverse AMR transmission

Re-assessment notes

Deferral – if you miss an assessment for certificated reasons judged acceptable by the Mitigation Committee, you will normally be either deferred in the assessment or an extension may be granted. The mark given for a re-assessment taken as a result of deferral will not be capped and will be treated as it would be if it were your first attempt at the assessment.

Referral – if you have failed the module overall (i.e. a final overall module mark of less than 50%) you will be required to submit a further assessment as necessary. If you are successful on referral, your overall module mark will be capped at 50%.
