Objectives

The discipline of Parasitology, has the overall objective to provide the fundamentals of the association between living organisms with particular emphasis on the parasitism that compromises the health of humans and some animals. Parasitic infections have a significant importance in the world around us, from the world's richest northern hemisphere to the poorest parts of Africa and require special monitoring result of climate changes to which we are daily witnessing. The discipline of parasitology intend to sensitize students to this reality.

Learning outcomes and competences

The discipline of parasitology should provide students with the ability to:

1) Identify the parasites that affect man by both macroscopic / microscopic observation of the structures that contribute the characterization of the parasite.

2) Analyze and understand the life cycles and the mechanisms of transmission to humans of the most prevalent parasitic diseases worldwide.

3) Know the indicated laboratorial diagnosis for the most important parasitic diseases of the world.

4) Advise the main preventive measures associated with the treatment, control and / or eradication of endo and ectoparasitoses.

Program

Theoretical Program: Introduction to Parasitology.

Study of protozoa and helminths with medical health interest and their respectively parasitic diseases. References to the history of the parasite and its parasitic diseases, morphology of the different parasite forms, life cycle, pathogenesis of infection, symptoms, geographic distribution, laboratory diagnosis, treatment and prophylaxis.  Protozoa: Plasmodium sp. Leishmania sp. Trypanosoma cruzi and T. brucei, Toxoplasma gondii, Giardia lamblia, Balantidium coli, Trichomonas vaginalis, Cryptosporidium parvum; Cystoisospora belli, Sarcocystis hominis, Cyclospora cayetanensis, Microsporidia, Entamoeba histolytica and free living Amoebas. Referencies to other flagellates of the digestive tract with unclear medical interest. Helminths: Fasciola hepatica, Schistosoma sp; Taenia solium and T. saginata, Hymenolepis nana and H. diminuta; Echinococcus granulosus, Dipylidium caninum, Diphyllobothrium latum, Ascaris lumbricoides, Enterobius vermicularis, Trichuris trichiura, Strongyloides stercoralis, Ancylostoma duodenale and Necator americanus, cutaneous larva migrans, visceral, Trichinella spiralis, Anisakis sp. Introduction to medical artropodology. Study of arthropods that most often cause human infection and study of their infection: bedbugs Cimex Cimex lectularis and Cimex  hemipterus; Sarcoptes scabiei; fleas Xenopsylla cheopis and Pulex irritans; lice Pediculus humanus and Phtirus pubis.

Laboratory Program:  macroscopic and/or microscopic morphology study of the parasitic forms from: Plasmodium sp. Leishmania sp., Toxoplasma gondii, Trypanosoma sp; Giardia lamblia; Amoebas; Trichomonas sp; Cryptosporidium parvum; Cystoisospora belli; Ascaris lumbricoides, Trichuris trichiura, Enterobius vermicularis; Hookworms; Storngyloides stercoralis; Fasciola hepatica, Schistosoma sp. Tenia sp. Hymenolepis sp. Equinococcus granulosus.

Eligibility for exams

 

Obtaining Frequency

The frequency of laboratory classes is compulsory, without being considered to the students whose attendance is below 75% of the classes provided. The student attendance at lectures is not compulsory.

 

Calculation formula of final grade

Assessment Components

Laboratory Evaluation: Performs in a laboratory classroom and consists in the execution of work (s) performed (s) in previous laboratory classes. Not being approved (minimum score of 9.5), the student will be admitted to the practical test on the final exam date defined in the academic calendar prepared by the Pedagogical Council. The approval of the laboratory evaluation is a prerequisite for admission to the student's written final exam. Students who are exempted by law from the presence of classes are called to carry out the practical final exam. The approval of the laboratory evaluation will be valid for 3 subsequent academic years and possibly two more years after examining each case.

Theoretical evaluation of the subjects taught in the laboratory and theoretical lectures: final written test. Students with a grade higher than 9.5 are considered approved. Oral examinations are not preview

Presentation of a power point about a subject of Parasitology: in laboratory classes will be presented a power point done by the students for about 20 min followed by a discussion of 10 minutes. The evaluation will be 0 to 20. The presentation of work is mandatory.

 Final grade: grade on the overall assessment of the discipline: 70% of the written test grade + 20% of the laboratorial test grade + 10% of the final note of the Power point presentation

 

Examinations or Special Assignments

 

Special Assignments Students who are exempted by law from the presence of classes are asked to perform the laboratorial final exam. The approval of this test is a prerequisite for admission to the student's in the written proof of the final exam. Special evaluation (TE, DA, ...) is performed according to the evaluation standards FFUP.

 

Special assessment (TE, DA, ...)

Special evaluation (TE, DA, ...) isperformed according to the evaluation standards FFUP.

Classification improvement

Improvement of the final classification

Whenever a student wants to improve the classification will necessarily have to perform the laboratory test and theoretical test.

The overall rating is the highest obtained in the two tests carried out.

Improving classification may be required only 1 single time, in one of the two examinations periods immediately subsequent to that they received approval.

Observations

It is assumed basic knowledge on Physiology, General Microbiology, Immunology, Cell Biology, Genetics, Biochemistry, Pharmacology, and some laboratory experience in microbiology.
