Prerequisites

Although there are no official prerequisites, students are advised to review the concepts that refer to the microbial world previously studied. Likewise, it is convenient to have a good knowledge of the subjects studied during the first semester of the Biomedical Sciences degree, as well as of the other subjects that are simultaneously taught during the second semester.


Objectives and Contextualisation

This is a compulsory subject of the Biomedical Sciences degree that introduce students to the microbial world, giving a general vision of microorganisms in connection with the rest of the living organisms, and the different environments in which microorganisms live.

This subject, given its introductory approach, providing the most basic concepts and competences related to Microbiology. Students can therefore deepen in the following courses the rest of subjects that are part of the nucleus of the Biomedical Sciences degree.

Objectives of the subject:

1. To broadly recognize the microbial diversity and to know how to distinguish the characteristics that define the different microbial groups.

2. Identify the different structures, as well as the composition of the prokaryotic cell.

3. To know the metabolic versatility of the different microbial groups, particularly that of prokaryotes.

4. To know the genomic variability of microorganisms and the main mechanisms for the exchange of genetic information in prokaryotes.

5. Recognize the main relationships of microorganisms with living beings and the physical environment they inhabit.

6. To know the role of microorganisms in the development of human societies, as well as their current and future applications.

7. To know how to perform basic calculations to determine microbiological parameters.

8. To understand basic laboratory techniques to work experimentally with microorganisms.

The subject of Fundamentals of Microbiology and Virology consists on two modules which have been programmed in an integrated way. The student will have to relate throughout the course the content and programmed activities to achieve the competences indicated in section 5 of this guide.

The two modules are the following:

Participatory theoretical classes: The student must acquire the scientific and technical knowledge of this subject by attending these classes and complementing them with the personal study of the topics explained. At the beginning of the course, students will receive a detailed calendar of the topics that will be dealt with throughout the course, as well as the bibliography that they will have to consult to prepare each theoretical class, and for the personal study of the topics explained. The teaching of each subject will be based on a theoretical exposition and on a brief discussion of the same. In addition, for each topic, the student will have a series of questions that will allow him/her to reflect and work personally on the topics covered.

Classroom practices: These classes are sessions aiming to:

A) work on methodological aspects,

B) facilitate the understanding of the knowledge exposed in the theoretical classes,

C) to train the student to design basic experiments on Microbiology and,

D) make a bridge between the participatory theoretical classes and the practical work of the laboratory, with the aim of integrating the theoretical knowledge with the practical classes.

The student will receive proposals of problems that will have to be developed during the course both in class and individually. In addition, the bibliography that will be consulted and the relation of each session with the subjects treated in the participative theoretical classes will also be indicated.

 

 

Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.


Assessment

Continous Assessment Activities

Title Weighting Hours ECTS Learning Outcomes
Multiple choice test (proposed works) 15% 0.5 0.02 14, 2, 3, 11, 7, 6, 5
Multiple choice test (theoretical concepts) 50% 1.5 0.06 14, 2, 3, 11, 10, 6, 5
Multiple-choice test (classroom practices) 20% 1 0.04 14, 2, 3, 11, 10, 8
Written and oral presentation 15% 1 0.04 1, 13, 12, 14, 2, 3, 4, 11, 10, 9, 7, 8, 6, 5, 15

 The evaluation of the subject will be individual and continued through the following tests:

Assessment module for theoretical classes (50% of the overall score).

A written multiple-choice test in which the student must demonstrate their degree of achievement of theoretical concepts. In order to approve this module, the student must get at least 5 in this test.

Evaluation module for classroom practices (50% of the overall score).

The evaluation of this activity will consist of the following tests:

a)  Written and oral presentation of a work related to a microorganism proposed by the teaching staff (25%)

b)  A written multiple-choice test corresponding to the practical problems done during the classroom practices and corresponding to the oral presented works (25%)

These tests will have a weight of 5 out of 10 points each one. To pass this module the student must obtain at least 5 in each of the tests.

The written and oral presentation will be carried out the last week of classes. All the written multiple-choice tests will be carried out the scheduled date for the evaluation of the subject.

 

To pass the subject, the student must obtain a qualification of 5 or higher in each module. Otherwise, the student will have to complete the retrieval test scheduled at the end of the semester and pass it with a mark equal to or greater than 5. The maximum score that can be obtained in this make-up test will be 5 points.

To be eligible for the retake process, the student should have been previously evaluated in a set of activities equaling at least two thirds of the final score of the course or module. Thus, the student will be graded as "No Avaluable" if the weight in of all conducted evaluation activities is less than 67% of the final score.

The students that have passed the subject have the option to improve the mark by doing an exam, at the end of the semester, in the date programmed for the retrieval test. The presentation to the examination to improve the mark implies the resignation of the qualification previously obtained and, in this case, the final mark of the subject will be the one obtained in this test. This exam will consist of an overall test of all the content of the subject and to overcome it, it will be necessary to obtain a mark equal to or greater than 5.

Single assessment  

The students who choose the single assessment must do the written work in group and the oral presentation of the seminars in face-to-face sessions since they are mandatory teaching activities. The evaluation will be the same as for the continuous assessment.

The single assessment consists of a final exam that will contain questions on the whole theoretical content of the subject, questions about the oral presentations and questions about the problems, as it is in the continuous assessment. This final assessment will correspond to the 75% of the final score of the subject: 50% corresponding to the theoretical part and 25% corresponding to the seminars. This single assessment test will be held coinciding with the same date for the last continuous assessment test. The same criterion will be applied to pass the subject as for the continuous assessment. The same retake system as for the continuous assessment will be applied. The revision of the final qualification will follow the same procedure as for the continuous assessment.
