DIAGNOSTIC TECHNIQUES OF CLINICAL MICROBIOLOGY
Learning outcomes of the course unit
Students have to know general characteristics of the pathogenic factors and basic technical aspects related to the laboratory diagnosis of infections caused by relevant parasites and viruses of medical interest. In addition, they must be able to apply this knowledge in the workplace.
Basic knowledge of biology, biochemistry and physiology are suitable to understand the course topics successfully.

Lectures supported by visual aids will be used to present and discuss the contents of the course.
Assessment methods and criteria
The outcomes of learning will be verified through an oral examination.
By questions regarding the topics of the course it will be determined whether the student has achieved the goal of basic knowledge in the field, in order to access the following years of the bachelor course in TLB.
