Aims of the Subject:
“Medical Biology” programme is realized in the first semester. The course is divided into 5 basic parts: general and molecular genetics, human genetics and cytogenetics, biology of human parasites, pathogenesis of parasitic diseases and diagnostic methods in parasitology.
The main aim of the „Medical Biology” course is to make the students ready to learn clinical subjects as well as to prophylaxis, diagnostics and therapeutics.
