Microbiology

Course objectives

Acquaintance of the pathogenic microorganisms in humans. Study of the relationships between host and pathogenic microorganisms in human infections and acquaintance of possible therapeutic and prophylactic approaches. At the end of the course the student must demonstrate to have acquired the intinsic acquaintance of the pathogenic organisms that caused infections in human; he must know how to characterize the pathogenic relationships between host and organisms in human infections; he must know the ethiology and pathologic mechanisms of most important and frequent infection caused by microorganisms; he must be aware of the available means for the control of the diseases. Particular attention will be paid to gender diversity in response to infections; to vaccines; to translational research approaches for the identification of new antimicrobial drugs and vaccines. Specific Objectives of the integrated course Knowledge and understanding: passing the exam guarantees the understanding of the relationships between host and pathogenic microorganisms in human infections and acquaintance of possible therapeutic and prophylactic approaches; knowledge of the ethiology and pathologic mechanisms of most important and frequent infection caused by microorganisms. The student knows gender diversity in response to infections; to vaccines; to translational research approaches for the identification of new antimicrobial drugs and vaccines. Ability to apply knowledge and understanding: passing the exam guarantees the ability to understand the ethiology and pathologic mechanisms of most important and frequent infection caused by microorganisms; know how to characterize the pathogenic relationships between host and organisms in human infections; the awareness of the available means for the control of the diseases. Autonomy of judgment: passing the exam implies the ability to critically judge the the general characteristics of viruses that cause human diseases, the mechanisms of viral pathogenesis, host antiviral defenses, diagnostic and therapeutic tools. Communication skills: passing the exam implies the ability to effectively use the communication tools of publications and scientific communications. Learning skills: passing the exam implies the transversal learning capacity common to the logic of scientific investigation in the biomedical field.
