Prerequisites

There are no official prerequisites to follow the course; nonetheless, it would be desirable if students review basic concepts of the microbial world previously acquired in the first courses of the Bachelor's Degree in Microbiology and good knowledge about the subjects coursed simultaneously in the first semester of the third course.

Objectives

This is a compulsory subject, a nuclear course from the degree of Microbiology, which introduces students to Food Microbiology. The achievement of the competencies of the course will allow students to acquire new knowledge related to other subjects subsequently coursed in the degree of Microbiology.

In addition to the learning outcomes listed in the following section, students at the end of this subject will be able to:

1.- Describe and analyse the ecology and activities of microorganisms in food.

      List the main groups of microorganisms in food

      Differentiate between spoilage and pathogenic microorganisms in food and other products.

      Distinguish between pathogenic microorganisms and microorganisms that indicate contamination.

      List the different origins and sources of microbial contamination of food

      Identify and distinguish the different types of factors that affect and control the growth of microorganisms in food

      Describe and interpret the basic principles of predictive microbiology

2.- Recognize, classify and review the current methods of culture, analysis and identification of microorganisms and/or their metabolic products in food.

      List the different methods used to determine the microbiological content of foods

      Describe the methodologies applied to the analysis of the different types of microorganisms and parasites present in food.

      Identify the techniques used in the isolation, cultivation and identification of pathogenic microorganisms.

      Identify the techniques used for the multiplication, detection and identification of viruses.

3.- Identify and interpret the main infections and poisonings caused by microorganisms and associated with food consumption.

      Relate and differentiate the most important microbial diseases transmitted by food with the ecophysiological needs of the specific microorganisms that produce them, the environmental characteristics of the food itself and the possible sources of contamination in each food.

4.- Identify and describe the different common microorganisms, alterers and pathogens associated with each type of food.

      Recognise the usual microbiota of environments, food and other derived products.

      Inform about the most relevant alterations related to each type of food and the preservation techniques used to avoid them.

5.- Use bibliography or Internet tools, specific to microbiology and other related sciences, both in English and in their own language.

      Review, classify and select information.

      Develop and publish an encyclopedic article on the Catalan Wikipedia in accordance with the specific monitoring guidelines established by Wikipedia itself.

      Demonstrate the ability to work individually, in groups, in multidisciplinary teams and in an international context.

The subject of Food Microbiology comprises two modules: theoretical classes and seminars. These have been programmed in an integrated way so that the student will have to relate throughout the course to the contents and activities programmed to achieve the competencies indicated previously in this guide.

The two modules are based on the following:

In the Theoretical Classes, the student must acquire the scientific-technical knowledge of this subject by attending these classes and complementing them with a personal study of the topics explained. At the beginning of the course, the student will be given a detailed calendar of the topics discussed throughout the course, as well as the bibliography that must be consulted to prepare the theoretical classes and for the personal study of the theoretical contents of the subject.

The Seminars module will be work sessions in two groups, each with half of the students, where two learning activities will be worked on:

- Microbiological analysis applied to food. Students will carry out practical activities complementary to the theoretical contents of the subject, aimed at the application of the main analysis methodologies used in food microbiology. The different sessions will combine questions, exercises and practical cases that will allow the knowledge acquired to be applied to the interpretation of results, problem solving and decision-making in the field of microbiological control and food safety. Attendance at this activity is mandatory.

- Viquiproject. The students, organized in groups of about four people, must create or improve an encyclopedic article of the Viquipèdia in Catalan related to the contents of the subject. The articles will be pre-selected by the teaching staff according to their relevance within the syllabus and their state of development in the Viquipèdia (non-existent or clearly improvable content in Catalan).

To facilitate learning and use of the wiki environment (interactive resources), two specific training sessions will be held in Viquipèdia editing (theory and practice) and there will be a space for support and resolution of doubts throughout the development of the activity (forum). The topics selected for the Viquiproyecto will be distributed among the different groups of students, and once elaborated and published in the Viquipèdia, the articles will be evaluated.

Various help resources can be consulted on the website of the Food Microbiology Viquiproject, including video tutorials, editing guides, style recommendations and other useful documentation for the preparation and publication of the articles.

Additional information:

In order to support the training activities indicated above, students will be able to carry out individual tutorials on the contents of the subject or in groups (Viquiproject) in the office of the teacher, Antoni Solé (C3-337), at hours previously arranged by email.

For a good follow-up of the subject, the student will have the complementary material that the teacher deems necessary and the presentation and the teaching guid in the Moodleclassroom.

You can also review all the information related to the WikiProject: Food microbiology UAB at the following link: WikiProject:Food microbiology UAB - Wikipedia, the free encyclopedia (wikipedia.org).

You can also consult the teaching space of the Degree Coordination to obtain updated information regarding the degree.

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

Theoretical Classes: Questionnaire with true/false questions 12 0.8 0.032 CM13, CM14, KM20, KM21, SM19, SM20

The evaluation of the subject will be individual and continuous through the following modules:

Evaluation module of the Theoretical Classes (60% of the final grade): Two written different eliminatory assessment exams will be assigned for this module, the first exam, with a weight of 32%, includes units 1 to 9, and the second exam, with a weight of 28%, includes units 10 to 22. These evaluations will be eliminatory if a minimum grade of 5 is obtained. Each test will include three parts: multiple choice questions; true or false questions and short questions, with a value of 6, 2 and 2 points out of 10, respectively.

Seminar assessment module (40% of the final grade). The evaluation of this module includes:

1.- Microbiological analysis applied to food (15% of the final grade). The seminar classes corresponding to this activity will be compulsory attendance. If a student in a seminar group cannot attend any of these sessions, they must communicate and justify it to the responsible teacher, as soon as possible, by email, and thus be able to attend the same session of the other group of seminars. If there is no clear justification, the change will not be valid, and like absence in any of the sessions, may entail a penalty in evaluating this training activity.

2.- Viquiproject: Preparation and publication of an informative article on Viquipedia (25% of the final grade). In this case, students must:

- Search and select quality academic bibliography (scientific articles, reviews and book chapters, preferably in open access) related to the assigned topic. This documentation will serve to structure, write and properly reference the article (viquiproyecto).

- Create or improve an article of the Viquipèdia in Catalan, the free and online encyclopedia, based on its initial state and the guidelines established in the Viquiproject: Microbiology of UAB foods. The evaluation will be based on compliance with the Monitoring Guidelines and specific criteria published on the viquiproyecto page and explained during the sessions of the seminar module. Among the aspects evaluated will be the scientific rigor of the contents, the quality and reliability of the sources used, the structure and organization of the article, the ability to synthesize, the quality of the writing and informative language, the appropriate use of graphic elements and infographics, as well as compliance with the editorial rules and the Viquipèdia style book.

For each of the assessment guidelines, students will have a specific subsection called "What should I review?", which describes in detail the aspects that will be taken into account during the assessment and the recommendations to achieve them correctly.

All the content incorporated in the article must respect the principles of academic authorship and the rules of citation of sources. The total or partial copying (similar paraphrasing) of texts from other works without the corresponding attribution will be considered plagiarism and will be treated in accordance with the current regulations of the University. Given that the activity consists of the production of original encyclopaedic content, the copying or literal translation of texts from scientific articles, books, websites or other editions of the Viquipèdia is not permitted.

The final grade for the Seminar Module will be the weighted sum of the percentages corresponding to the different assessment activities.


The punctuality and attitude of the student will be considered and evaluated both in theoretical classes and especially in seminars. In no case this follow-up will entail an increase in the grade, but failure to comply with this may mean a reduction of up to 25% of the final grade obtained in this subject.

Students who cannot attend an individual assessment test for justified reasons (such as a health problem, death of a relative up to a second degree, accident, elite athlete status, and have a compulsory competition or sports activity, etc.) and provide the corresponding official documentation to the degree coordinator (official medical certificate explicitly stating their inability to take an exam, police report, justification from the competent sports body, etc.), will have the right to take the test on another date. The degree coordinator will ensure the concretion of this after consultation with the teacher of the subject affected.

To pass the subject, a minimum grade of 5 must be obtained in each module. Students who do not pass the evaluations of the different modules of the subject will be able to recover them on the scheduled date at the end of the semester (Recovery exam) where the minimum grade to pass will also be 5. In order to be able to attend the recovery exam, the studentmust have been previously evaluated for continuous assessment activities that are equivalent to 2/3 (67%) of the final grade. In the case of the theoretical classes module, they willonly have to submit to the individual evaluation test not passed previously, and that will consist of a multiple-choice questionnaire that will include multiple choice, true/false and short questions. In the case of the seminar module, theymust be submitted to a written test based on test and/or true/false questions referring to the different activities worked during these classes. Students who do not obtain the minimum required qualification cannot pass the subject. In this case, the maximum final grade for the subject will be 4.

Students will obtain the "Non-Valuable" qualification when the evaluation activities carried out have a weighting of less than 67% in the final grade.

Students who want to improve the final grade of the subject (theory and/or seminars) will have to submit to a specific evaluation test that will take place on the same day that the recovery exam is done. These improvement tests will include all the contents taught during the theoretical classes (theory improvement) and/or all the contents taught during the seminar classes (seminar improvement) and will consist of a questionnaire-type test and/or true/false where the student must demonstrate that he has improved his degree of knowledge of the subject. The presentation of the student to this improvement exam will entail the waiver of the qualification previously obtained.


Single assessment

Single assessment consists of a single examination in which the two modules of the subject will be assessed: theory classes and seminars. Regarding the Theoretical Classes module, all the contents of the entire program of the subject will be evaluated and consist of test questions, true/false questions, and short questions. The noteobtained in this part will represent 60 % of the final grade of the subject and must be equal to or greater than 5.

Regarding the Seminars module, in the single assessment, the activities related to the Microbiological analysis applied to food will be evaluated through test questions and true/false and will have a weight of 15 % of the final grade of the subject and must also be equal to or greater than 5.

As for the rest of the activities programmed within the Seminars module: Viquiproject: Preparation and publication of an informative article on Viquipedia, the same procedure will be followed as in the continuous assessment with a weight of 25 % of the final grade of the subject.

The single assessment exam will coincide with the same date set in the calendar for the last partial assessment exam and the same recovery system will be applied as for continuous assessment.


Use of Artificial Intelligence (AI) technologies:

For this subject, the use of the AI is allowed exclusively in support tasks, such as bibliographic or information search, text correction or translations, or others at the discretion of the teaching staff.

The student should clearly identify which parts have been generated with this technology, specify the tools used, and include critical reflection on how these have influenced the process and the final outcome of the activity. As for the Viquiproyecto, this information should be written on the talk page of the assigned encyclopedic article.

The non-transparency of the use of AI in assessment activities will be considered academic dishonesty and may lead to a partial or total penalty in the grade of the activity, or greater sanctions in cases of severity.


Irregularities in evaluation acts

The performance of any irregularity in an assessment act (academic fraud, plagiarism or improper use of AI, unless this use is expressly authorised in the teaching guide), which may lead to a significant variation in the grade, means that this act will be graded with a 0. In the event that the teaching guide provides that in order to pass the subject it is an essential requirement to have obtained a minimum grade in this assessment act or that there are various irregularities in the assessment acts of the same subject, the final grade for this subject will be 0. Apart from this, a disciplinary process may be instituted for the student who incurs in any of these irregularities.
