London School of Hygiene & Tropical Medicine

The module deals with biology of bacteria as pathogens. It focuses on the ways in which the procedures that are used to investigate bacteria from clinical materials (specimens collected from ill people) reflect current understanding of the pathogenesis of bacterial infections and how infections can be controlled.

The overall module aims are to give students an understanding of: 

• The biology of bacteria as pathogens.
• How samples are collected and analysed and how procedures used to investigate bacteria from clinical materials reflect current understanding of the pathogenesis of bacterial infections.
• How bacterial infections can be prevented and treated.

Intended learning outcomes

Upon successful completion of the module a student will be able to: 

1. Demonstrate a systematic understanding of the pathogenesis of bacterial infections in humans by explaining and comparing their microbiology and epidemiology.
2. Apply specialist theoretical knowledge and demonstrate a practical understanding of relevant clinical samples to be collected, if presented with infected patients, and associated appropriate laboratory investigations.
3. Apply specialist theoretical knowledge to determine appropriate investigations on clinical samples of bacterial infections, and to interpret and evaluate the results from diagnostic techniques.

Assessment

This module is assessed by:

• A 2,500 word Assessed Assignment (30%).
• A 3,600 word Time Limited Assessment (70%).

Mode of delivery

Our distance learning modules are delivered entirely online via directed self-study and online materials via the Virtual Learning Environment.

Module duration

Distance learning module studies begin at the start of October each year. Students may start their studies at any time once they gain access to Moodle (the virtual learning environment) and study materials, and work through the materials in line with the assessment schedules. The study year runs from the beginning of October through to June examinations. Some students also study between June and September with extended tutorial support (e.g. those undertaking projects, the Clinical Trials integrating report, or two of the Epidemiology modules). Deadlines for submission of coursework vary per programme but are usually in February, March, May, and September.

How you'll study

Our distance learning programmes are predominantly online and largely self-directed study to enable you to study independently and at times convenient to you. You'll have access to tutorial support and the ability to interact with other students and form study groups throughout the study year via the discussions in our Virtual Learning Environment, Moodle.
