PRACTICAL AND BIOMEDICAL BACTERIOLOGY - 2021/2
Module code: BMS1035
In light of the Covid-19 pandemic, and in a departure from previous academic years and previously published information, the University has had to change the delivery (and in some cases the content) of its programmes, together with certain University services and facilities for the academic year 2020/21.
These changes include the implementation of a hybrid teaching approach during 2020/21. Detailed information on all changes is available at: https://www.surrey.ac.uk/coronavirus/course-changes. This webpage sets out information relating to general University changes, and will also direct you to consider additional specific information relating to your chosen programme.
Prior to registering online, you must read this general information and all relevant additional programme specific information. By completing online registration, you acknowledge that you have read such content, and accept all such changes.
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.

• The Enterobacteriaceae - isolation and characterisation
• Pseudomonads and use of the membrane filtration technique for isolation from swimming pool water
• Vibrios and the use of the Most Probable Number method for enumeration
• Staphylococcus and Micrococcus:
a. Isolation from the body and wound infections
b. Monitoring the microbiological quality of air
• Bacillaceae: The Gram positive spore forming rods
a. Antibiotic production (Actinomycetes and related bacteria)
b. Antimicrobial interaction and testing for antibiotic resistance
• The pathogenic bacteria associated with gastroenteritis
|Assessment type||Unit of assessment||Weighting|
|Practical based assessment||COURSEWORK - PRACTICAL LABORATORY WRITE-UP||25|
|School-timetabled exam/test||COURSEWORK - SURREYLEARN SHORT ANSWER AND MCQ ASSESSMENT (30 MINUTES)||25|
|Practical based assessment||EXAMINATION - PRACTICAL EXAMINATION (180 MINUTES)||50|
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, a written report, and a short online assessment. In addition, students will work in small groups in successive practicals.
Thus, the summative assessment for this module consists of:
- A full practical report (1000-2000)- 25% of total marks
- An on-line quiz (30 minutes) – 25% of total marks
- A 3 hour practical exam – 50% of total marks
Formative assessment and feedback
A formative practical report proforma, which is not graded, will be completed by the students in the practical session with immediate feedback to inform students on subsequent submission of the full practical write-up. Written feedback will be provided on the full practical write-up and automatically generated feedback will be available from the online assessment. There is also a drop-in exam revision session where the students can practice techniques and calculations.
- 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 on successive practical sessions

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. Working in pairs, the students also get the opportunity to work together on successive linked praticals.
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.
