Principles of Infectious Disease
|Unit level||Level 2|
|Teaching period(s)||Semester 2|
|Offered by||School of Biological Sciences|
|Available as a free choice unit?||No|
Principles of Infectious Disease will provide you with a broad understanding of the biology of microbial infections, with an emphasis on bacterial human infections. You will study the mechanisms of microbial pathogenicity, starting with pathogen transmission and entry into the host, progressing through adhesion and invasion, to cell and tissue damage and host responses to injury. The diseases studied will include tuberculosis, cholera, listeriosis. salmonellosis, gonorrhoea and pseudomembranous colitis.
|Unit title||Unit code||Requirement type||Description|
|Microbes, Humankind and the Environment||BIOL10532||Pre-Requisite||Compulsory|
|Fundamentals of Bacteriology||BIOL21181||Co-Requisite||Recommended|
To explore the fundamentals of how microorganisms cause disease and the interactions that occur between a pathogen and host during infection. To study the mechanisms of microbial pathogenicity (focussing mainly on bacteria), starting with pathogen transmission and entry into the host, progressing through adhesion, invasion and pathogen survival strategies within a host, to cell and tissue damage and host responses to infection. To gain a detailed understanding of the mechanisms of pathogenesis and disease for exemplary human pathogens.
On successful completion of this unit, students should be able to:
- Define the key host defences in preventing microbial infections and explain how they protect against bacterial pathogens.
- Describe the strategies used by bacteria to penetrate host external defences and explain, using examples, the mechanisms used in host colonisation and/or invasion.
- Describe, including examples, bacterial strategies for avoiding killing by phagocytes and explain how they function.
- Describe bacterial strategies for evading complement and antibodies and explain the mechanisms involved.
- Outline key factors that contribute to opportunistic infections.
- Describe the burden of fungal infections in humans and the virulence mechanisms of key fungal pathogens
- Define the structural features of bacterial products that contribute to the pathology of infectious disease (including endotoxin, exotoxins, lipoarabinommannan, pili, polysaccharide capsules, urease, invasins and secreted effector proteins. Use this information to explain how they function.
- Illustrate the mechanisms of action of bacterial exotoxins. Compare and contrast their structures and mechanisms of action.
- Explain the mechanisms of pathogenesis of selected human pathogens in detail (these representing paradigms of pathogen-host interactions) and analyse how these mechanisms promote survival within a host.
- Describe the main classes of antibiotics and their targets and discuss examples of antibiotic resistance.
- Analytical skills
- Discussion of a research paper and e-learning exercise require students to analyse experimental data and interpret results.
- Oral communication
- Students encouraged to answer questions during lectures
- Problem solving
- e-learning questions based on problem solving
- Discussion of a research paper and e-learning exercise focused on primary research papers. Students encouraged to read research papers and review articles.
- Written communication
- Short note and essay questions in examination
Feedback will be given on the eLearning coursework exercises and by end of semester exam marks. This will include: (i) formative individual feedback to all students regarding performance in the eLearning activities, and (ii) general feedback on exam performance by releasing a document addressing general strengths and weaknesses of answers and how questions were answered, and (iii) individual feedback on exam performance will be given by a drop-in session run by the unit coordinator or by individual correspondence (written or verbal) upon request.
Students will also be provided with the opportunity (non-assessed) to write a practice exam essay/short answer prior to the exam and will be given individual formative feedback. Optional (non-assessed) e-learning quizzes will also be available throughout the course for students to gain formative feedback on their understanding of lecture material.
