Learning objectives

The course aims to convey to the student the basic principles of
biology that are necessary for understanding the
microbiology. The proposed topics will allow the student to
acquire the tools to describe the structures and functions
microbial, the recognition of the main bacteria taxa, according to most
recent phylogenetic theories. In this way the student will be provided with the ability to understand the world of microorganisms as a part essential of ecosystems.


Have sufficient knowledge of general biology and biochemistry.

Teaching methods

Oral lectures with continual references to the general principles of the
practice in the laboratory.

Assessment methods and criteria

The learning assessment methods require a written test
on the topics covered.
The written test consists of a series of closed-field questions and two
open questions in which the learning level of the
disciplinary theoretical knowledge and the ability to apply them
student knowledge. Each question will be given a score. The sum of the correct answers will allow the final grade to be obtained.

Other information

The course promotes the acquisition of independent judgment, in
consideration of previous general knowledge and specific information
obtained from suggested textbooks and educational materials provided.
