MICROBIAL COMMUNITIES AND INTERACTIONS - 2026/7

Module code: BMS3114

Module Overview

Students will integrate what they have learnt in the previous modules, using their knowledge on Microbiology (BMS1026), Practical and Biomedical Bacteriology (BMS1035) and Medical Microbiology (BMS2085)

The study of microbiology often involves learning about the properties of single species, but in nature microbes rarely exist in isolation and are instead part of a rich and diverse ecosystem. Together with their ability to communicate via chemical signalling, the world of microbes reveals interesting complexities with relevance to health and disease, and biotechnology.

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate: · An understanding of the existence of microbes as populations, and the interactions that govern the properties of these microbial consortia. · Ability to interpret and draw conclusions relating to this discipline of microbiology from data generated from laboratory practical classes. Thus, the summative assessment for this module consists of: · Laboratory notebook assessment · Two-hour exam: One essay-style answer from a choice of three questions; 30 MCQ questions Formative assessment and feedback: SurreyLearn practice tests will provide feedback to the students of their knowledge and understanding. Formative feedback is given part-way through the series of practical classes

Module aims

  • Enable students to gain an understanding of the interactions between microbes existing as populations and communities
  • Develop a critical understanding of how models of communication systems in microbial populations can be applied to such phenomena as disease pathology and generation of energy
  • Develop understanding of how microbes can be manipulated in vitro to display evidence of communication

Methods of Teaching / Learning

The learning and teaching strategy is designed to ensure that students achieve the module learning outcomes through developing competencies and a critical understanding of research in complex of microbial communities. The corresponding aspects of the curriculum framework (employability, digital capability, global and cultural intelligence, sustainability, resourcefulness and resilience) are also integrated into themes within the module. The learning and teaching methods include:The theoretical elements are taught in the first part of the module and are delivered as lectures.The practical classes in the second half of the module are designed to consolidate the theoretical elements and develop greater critical understanding of microbial communities and interactions.

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.

Other information

Resourcefulness & resilience: The assessments for this module rely on the ability to collect and interpret data produced in practical sessions. The practicals will run in groups, which will allow students to develop teamwork skills, problem-solving, decision-making, self-efficacity, self-regulation and confidence. Global & cultural capabilities: Students will work in small groups during the practical sessions which will encourage and engage students in working with other students from different cultures and abilities to achieve an end goal. Digital capabilities: Students will utilize the virtual learning environment SurreyLearn and other digital resources. The skills learned will be applied in the assignments they undertake to equip the students for a variety of modern professions. Employability: Transferable skills such as the ability to work in a team, report findings in a scientific manner and ability to identify clades will equip students for a variety of modern professions.
