Microbiology & Human Disease
Run by School of Medical Sciences
10 Credits or 5 ECTS Credits
Organiser: Mr Merf Williams
Overall aims and purpose
This module aims to expand upon the specialist medical microbiology knowledge a student has gained over the preceding two years.
The module discusses the role of the Medical Microbiology Laboratory in infectious disease diagnosis. The topics of sterilisation, disinfection and aseptic technique will be examined and their role in establishing and maintaining a safe working environment. The concept of the Normal flora will be studied together with its role in disease and factors affecting microbial pathogenesis. Clinically significant micro-organisms involved in infectious disease of all major and minor organ systems will be addressed, together with the host's defense against infection and the increased susceptibility of the immune compromised host. The principles and mode of action of classes of chemotherapeutic agents, the efficacy of antibiotics in the host and techniques used to measure antibiotic susceptibility in vitro will be examined, including the problem of health care associated infections, antibiotic resistance and cross infection. The microbiology of food and water and the role of the environment in infectious diseases will be considered. Techniques used to detect and identify micro-organisms including microscopy, culture, serology, gene amplification and recent automated methods will be described. Case study scenarios will be followed up in a laboratory setting (either wet or dry) with students expected to identify given cultures of bacteria as far as possible and to build on their experiences from second year.
Category A (70%-100%):
An excellent student should be able to demonstrate the skills necessary for self-managed and lifelong learning (working independently, time management and organisation) and have a detailed in depth knowledge of all aspects of the module. Written answers should have an extremely high standard of presentation, structure and clarity with a very well argued coverage of accurate and relevant information. In practicals, the student in addition to demonstrating critical appreciation of the strengths and weaknesses of the experimental procedure and their theoretical background and obtain and interpret high-quality results must show extensive background reading of current relevant information. Evidence of extra reading and critical anlysis required for the higher A categories.
Category B (60%-69%):
A good student should have a thorough factual knowledge across all aspects of the module, and be able to detail examples where appropriate. Written answers should demonstrate an ability to critically synthesise lecture material and information from background reading. In practicals, the student must demonstrate critical appreciation of the strengths and weaknesses of the experimental procedure and their theoretical background and obtain and interpret high-quality results.
Category D (40%-49%):
A threshold student should have a basic knowledge of the essential facts and key concepts in medical microbiology presented in this module. Written answers should demonstrate an ability to organise relevant lecture material into a coherent argument For the practical report, the student must demonstrate a basic understanding of the aims and objectives of the experiment and be able to present and interpret the data in a satisfactory manner.
C- to C+
Category C (50%-59%):
A less engaged student would have a correct knowledge across most aspects of the module, and may not be able to provide all the required detail examples where appropriate. Written answers should demonstrate an ability to synthesise lecture material. No evidence of background reading. In practicals, the student should be able to understand the strengths and weaknesses of the experimental procedure and their theoretical background and obtain and interpret the results. The interpretation may reveal knowledge gaps and/or misunderstandings.
Demonstrate an ability to follow experimental procedures (SOPs) for the laboratory investigation of disease with interpretation and discussion in a written report
Acquire an understanding of the principles and wider applications of techniques used to detect and identify a variety of disease causing micro-organisms, including safety procedures.
Critically evaluate the use of anti-microbial products in controlling micro-organisms and discuss the mechanisms of action and development of resistance.
Critically discuss the pathogenicity and epidemiology of selected medically important micro-organisms including the resulting host reactions and selected treatments strategies.
This is a 2000 word report based on four patient scenarios and two spot tests (available on Blackboard), with students participating in a laboratory session (wet practical) or if not able to participate, for any valid reason, can participate via given results (dry practical).
|EXAM||Final module exam||
This is a 2.5hr timed exam consisting of two parts. Part A where the student is expected to answer 3 from 5 short answer questions in 1 hr, followed by Part B where the student is expected to answer 2 from 4 critical essay style questions in 1.5hrs.
Teaching and Learning Strategy
10 x 2hr weekly Interactive synchronous and asynchronous lectures and flipped classroom style tutorials and discussions.
|Practical classes and workshops||
Practical sessions of 6 hours duration in the C4 (Cat II) Laboratory. The first part is a demonstration/practice session prior to the assessed practical. if the wet laboratory session is not able to take place or the student cannot attend, filmed demonstrations of the use of the laboratory equipment and commercial identification kits will be available on Blackboard.
