At the end of the course, student will be able to:
• design laboratory settings for their own research projects
• apply the basics of molecular cloning as a specific breakout-technique of molecular diagnosis
• apply the value of basic microscopical and immunological research methods in an experimental animal model
• apply, analyze and evaluate up-to-date laboratory methods and techniques in the field of direct diagnosis of infectious diseases, such as mycobacterial DNA extractions, conventional PCR, dry-reagent-based PCR, quantitative real-time PCR as well as loop-mediated isothermal amplification procedures, and parasite isolation in the example of Schistosoma mansoni
• appraise requirements for working in a S2-laboratory
Assessment Procedures:
Written theoretical examination (multiple choice questions, 30 minutes) in the application and evaluation of molecular methods in diagnosis of tropical infectious diseases (PCR and cloning) on day 4. In case of failure, students will be subjected to an audio-visual oral online examination. Grading: A-D, F.

In addition, students will be assessed daily by the facilitators for their active participation on a pass/ fail basis. Day 5 will be assessed exclusively in this manner.
Polymerase Chain Reaction
• Application of different PCR formats and techniques for the diagnosis of mycobacterial infections (e.g. Buruli ulcer) in the context of various clinical questions (conventional, gel based PCR, dry-reagent-based PCR, quantitative real-time PCR, loop-mediated isothermal amplification procedures (LAMP))
• Trouble-shooting
• Parameters for validation of various PCR assays

Molecular Cloning Techniques
Learning and applying molecular cloning techniques. A target gene, encoding for the fluorescent mCherry protein, will be amplified and cloned into a standard plasmid vector. Competent E. coli bacteria will then be transformed with the newly generated transgene carrying plasmid. After culturing the bacteria in selective media, plasmids will be isolated and analyzed for the presence of the transgene. These techniques can for example be used to generate standards for Real Time PCR based quantification of pathogens.

Parasitology lifecycle based methods (Schistosomiasis)

• Familiarization of students through pre-course assignment with the etiology, clinical presentation and particularly the life cycle of schistosomiasis.
• On-campus familiarization with diagnostic parasitology laboratory facilities. Discussion of ethical aspects of animal models for basic immunological research questions in the field of host-parasite interaction (schistosome mouse model). Presentation of the different life cycle steps of schistosomiasis in two hosts (mouse and molluscs). Perform methods for qualitative and quantitative analysis of schistosome infestation. Demonstration of methods to assess the hosts immune responses at given infection timepoints.
