Tuberculosis and other Mycobacterioses


After this unit, students should be able to:
1. To know the biological characteristics of the etiological agent of TB and other mycobacterial infections.
3. To understand the role of the mycobacteriology laboratory in the health system and in the prevention of the transmission of resistant strains and their interconnection with the co-infection with HIV.
4. To understand and describe the imunofisiopathology of mycobacterial infections associating it with the clinical manifestations of different forms of TB.
5. To acquire good biosecurity practices in the handling of resistant strains, in determining their resistance and how to manage TB laboratories with quality control.
6. To master the classic techniques of laboratorial mycobacteriology, theoretical and practical knowledge of the laboratory diagnosis of TB, leprosy and other mycobacterial infections.

Teaching method

1) Lectures, slide show based, accompanied with indication of complementary bibliography.
2) Lectures with introduction ton and resolution of case studies forcing the application of methodologies addressed diagnosis/monitoring/characterization of the mycobacteria infections and characterization of drug resistance profiles.
3) Laboratory classes, based on the resolution of case-study based on clinical or laboratory cases.

Evaluation method

Assessment is performed by a written exam to students that attended at least 2/3 of classes.
