Laboratory Diagnostic Presentation Review Guidelines

The diagnostic assay presentation is an opportunity to demonstrate your knowledge and understanding of current laboratory techniques for the detection of viral, prion, parasitic and fungal pathogens. You will provide a synopsis of their life cycle, diagnosis, and treatment in a review of recent literature (<10 years old). In this assessment you will compare two pathogens which infect similar tissues or organ systems and examine the laboratory techniques used for their detection together with descriptions of transmission, pathogenesis, and treatment of these pathogens.

You must choose two different pathogen types, for example a virus and a bacteria, a fungus and a parasite, or a prion and a virus but you are not limited to these combinations. Examples of a target tissue or organ could be the respiratory tract, gastrointestinal tract, central nervous system, Genito-urinary etc.

To achieve this, you will need to:

1: Identify two suitable pathogens which infect the same tissue or organ. If you need guidance selecting your pathogens, please consult the unit coordinator for guidance.

2: Research the literature on both past & current diagnostic techniques including advances in diagnosis using molecular techniques and providing information on the pathogenesis and treatment of the chosen pathogen.

3: You will design and record a 10-minute (+/- 10%) video presentation for assessment. Upload the completed recording to YouTube as an unlisted video and the URL included in your PowerPoint submission on Moodle.

Process Choose a Target Tissue Organ

Choose two different pathogen types which infect the same target tissue/organ, for example a virus and a parasite, a fungus and a parasite, or a bacteria

and a virus which may infect the brain. You are not limited to these combinations.

• Give an introductory background to each pathogen, this should include information on transmission, pathogenesis and treatment.

• Design and record a 10-minute (+/- 10%) video presentation (including PowerPoint presentation) for assessment. a. Compare the similarities between the two pathogens in terms of the laboratory techniques used for their detection together with a

description of transmission, pathogenesis, and treatment of these pathogens. Then provide information on how they differ based on these

characteristics. Include information on use of molecular based tests.

b. Provide a conclusion that draws together the findings and gives a capstone to your assignment.

Instructions

Use PubMed and/or other databases to search for literature relating to the selected pathogens for detection of your chosen bacteria. Read and reference

at least 5 papers (From the last 10 years) for each organism. Use these paper to source your background information and inform your comparisons.
