Learning Objectives
At the end of this course the students shall acquire knowledge concerning the nature and characteristics of the main infectious agents (bacteria, fungi, parasites and viruses). They will know the mode of their transmission. They will acquire knowledge of about the cellular and molecular mechanisms of microbial and viral pathogenicity and the interactionsbetweeninfectious agent and host. They will learn the mechanisms of action of antimicrobial and antiviral agents and the mechanisms of microbial drug resistance. They will know the principles of laboratory diagnosis of infections. The studentsy will acquire athe general vision of the main pathogenic agents of medical interest.
