Unit level | FHEQ level 7 – master's degree or fourth year of an integrated master's degree |
Teaching period(s) | Semester 1 |

Overview
Microbial pathogenesis will be explored illustrated by studying selected infections in detail that will serve as illustrative paradigms relating to the wider field. Therapeutic, diagnostic and vaccination strategies will be explored as well as epidemiology and clinical presentation of relevant diseases. Unit will be delivered via lectures and a dedicated seminar series.
Aims
The unit aims to: provides students with in depth, up to date understanding of the molecular basis of host-pathogen interactions in healthy and diseased settings. Specifically, the mechanisms by which bacteria, fungi, viruses, parasites are able to colonise and establish infections will be addressed as well the pathogen/host interactions that subvert/modify the ability of the host to respond to infections.

Knowledge and understanding
- Understand the molecular and cellular mechanisms by which pathogens (viruses, bacteria, fungi and parasites) cause infection in man.
- Understand the immune evasion strategies used by various pathogens to circumvent host defences by modification of the host's cellular physiology
- Understand the problem of antimicrobial resistance and nosocomial infections.
- Understand the importance and change of microbiome in health and infection disease conditions
- Understand contemporary approaches used to study the major pathogens of human importance.
- Describe the current challenges of infection control and vaccine development.
