At the end of the course the student will have acquired a general idea about the different types of parasites and medical importance in the diagnosis of pathology and fight against the parasites in their various stages of development. The student will have a general idea about diseases and complications. Finally the student should be able to compare the different types of parasites in each class and each class by its branch.

During the exercises, students should be able to identify under the microscope parasites through annotated diagrams. Objectives: At the end of this course, students will recognize the different types of parasites, their form at different stages of their evolution. Also identify and compare parasites and classified in their own phylum. In the end about differential characters of major pests and diseases transmitted by them.
