PRACTICAL AND BIOMEDICAL BACTERIOLOGY - 2018/9

Module code: BMS1035

Module Overview

This is a practical module, the aim of which, is to equip students with the key technical skills used in bacteriology and to familiarize them with key diagnostic tests. It also introduces students to a range of medically and environmentally important bacteria and is a   key module for the microbiology programs.

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate: their understanding of the techniques, and ability to physically carry these out, through a practical exam, written reports, and short online assessments. In addition, students work in small groups towards a poster presentation concerning a named bacterium.  

Thus, the summative assessment for this module consists of:

·         Four full practical reports (50%) (500-2000 words)

·         Three short online assessments (13%) (20 minutes each)

·         A group poster presentation (7%)

·         3hr practical exam (30%)

Formative assessment and feedback

Students receive extensive written and verbal feedback on their practical write-ups and automatically generated feedback from  the online assessments. There is also a drop-in exam revision session where the students can practice techniques and calculations.  

Module aims

  • To re-familiarise students with the techniques of microscopy and the production and handling of pure cultures
  • To equip students with a variety of enumeration techniques for isolating important bacteria from water sources
  • To familiarise students with basic skills for isolating selected groups of bacteria from different environments
  • To familiarise students with basic skills for isolating and identifying pathogenic bacteria in clinical samples
  • To provide familiarity with a wide range of commonly used selective and diagnostic media
  • To provide an introduction to antibiotic producing organisms and the techniques using to detect antibiotic resistance in a clinical setting
  • To provide an opportunity for work in small groups towards a poster presentation

Methods of Teaching / Learning

The learning and teaching strategy is designed to: equip students with the  essential practical skills, and provide them with the background knowledge required for  bacteriology. Through practical and hands-on experience it is also designed to familiarize them with important groups of bacteria. 

The learning and teaching methods include: hands-on and direct practical experience of the techniques and bacteria (3hr practicals x 10). Student understanding is assessed and reinforced through practical write ups and feedback, and via short online assessments. As part of a small group (5), the students also get the opportunity to work together to produce a poster on an important bacterium. 

 

 

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
