00714 - Microbiology (AK-A)

Learning outcomes

At the end of the course, the student will know:

• žgeneral characteristic of bacteria, viruses, protozoa, fungi and parasites
• žroutes of transmission
• žthe establishment of pathogenic host-parasite interaction
• žincubation period
• žthe role of immunity during the course of infection
• žthe meaning of production of infection and production of disease
• žthe diagnosis of infection (direct and indirect). Collection of specimens, request for testing, tests employed, interpretation of tests
• žbasic concept of prophylaxis and therapy
• žprinciple of treatment. Antimicrobial drugs and mechanism of resistance
• žmost relevant bacteria (focusing on their characteristic, mechanism of action, symptoms, diagnosis, therapy, available vaccine)
• žmost relevant viruses (focusing on their characteristic, mechanism of action, symptoms, diagnosis, therapy, available vaccine)
• žmost relevant protozoa, fungi and parasites (focusing on their characteristic, mechanism of action, symptoms, diagnosis, therapy, available vaccine).

Readings/Bibliography

Suggested text-book: Michele La Placa. Principi di Microbiologia Medica, Edises, XIV Ed.

Teaching methods

In-class lectures will be supported by video projector and PC.

Assessment methods

The examination will evaluate whether the students have mastered the above listed skills and have reached the teaching objectives. The final oral examination will focus on specific questions about  bacteriology, virology, mycology and parassitology (the mechanisms of pathogenesis, routes of transmission, microbiological diagnosis, therapy and vaccines).

The student must answer at least 3 questions related to the program.

 

Teaching tools

In-class lectures will be supported by slides. Most of slides will be available online at the end of the course (AMS Campus, http//campus.unibo.it).
