Microbiologia Molecolare
A.Y. 2026/2027
Learning objectives
The course aims to provide participants with a broad understanding of molecular microbiology and the molecular basis of diseases relevant to veterinary medicine and animal sciences. It will also provide students with information on the main inflammatory and immune reactions against pathogens, which will be described at the molecular level, and on the main molecular mechanisms associated with pathogens related to microbial pathogenicity.
Expected learning outcomes
1. Knowledge and Understanding: By the end of the course, students should be able to demonstrate the following knowledge:
- Comprehend the molecular mechanisms of replication, transcription, and translation in microorganisms.
- Discover how bacteria control gene expression and adapt to environmental stresses.
- Know the methods of microbial genetic exchange (conjugation, transformation, transduction) and mechanisms of antibiotic resistance.
- Understand the molecular interactions between pathogens and host organisms, including key pathogenic and inflammatory mechanisms.
2. Applying knowledge and understanding:
Students should be capable of applying their knowledge and concepts to:
- Examine and interpret experimental data from genetic and molecular analyses of microbial strains.
- Develop laboratory protocols for microbial genetic engineering or nucleic acid analysis (including PCR, cloning, and sequencing).
- Purify and identify the primary blood cell populations involved in antimicrobial defense mechanisms.
3. Making Judgment:
Students are expected to develop critical analysis skills in molecular microbiology, with targeted exercises in hematology and microbiology aiding this development.
4. Communication Skills:
Students should demonstrate their understanding by using correct scientific terminology, especially concerning the course topics. Presenting a selected topic from the course is intended to enhance their ability to communicate clearly and engage in scientific discussions.
5. Lifelong learning skills:
Students should be capable of independently applying their knowledge. This involves reading, analyzing, and interpreting original scientific articles, as well as using genomic databases, bioinformatics tools, proteomics, and sequencing platforms such as NCBI or Ensembl to access information about genes, microbial genomes, and associated proteins.

Teaching methods
Lectures and practices.
The lessons are available through the ARIEL platform and are updated every year.
The exercises will be a combination of seminars, digital, and practical sessions, conducted in the computer room and laboratory. Proteomics and transcriptomics case studies of infectious diseases of veterinary interest will be analysed through a group work approach. Students will be trained in bioinformatics analysis using the most common pipelines to characterise the main pathways involved in the molecular pathogenesis of specific infectious diseases.

Teaching Resources
The slides of the course will be uploaded on the ARIEL learning platform
Assessment methods and Criteria
The course exam is written with questions related to the three areas of the course, on the Moodle platform. The exam consists of multiple-choice questions (one correct answer, 4 options to choose from). Each question on the exam will be taken exclusively from the material provided in class and practice, and will be made available on the ARIEL platform.
Students have the option of breaking down the exam into a mid-term exam and a final exam, of 64 MCQ each, or take the exam in a single exam, of 128 MCQ. 0.5 points will be awarded for each positive response. The exam lasts 1 hour for the intermediate exams and two hours for the overall exam. The result of the intermediate test will be valid only for the first exam session.
