Parasitology. Teaching Guide

Parasite of de parasites. Inside a She-oak gall is an insect larva, and on the larva are dozens of tiny red mites

The course Parasitology studies the parasites and their effects, for their scientific, ecological interest and in human and animal health. It is a science of sanitary, economic, and scientific importance since the parasites cause millions of deaths and diseases, enormous losses in livestock and crops, and their study teaches us to know better the living beings and ecosystems.

The first unit is about the parasites and the science of Parasitology, the second of protozoan parasites, third of helminths or parasitic worms, the fourth of parasitic arthropods and the fifth of two special cases of parasitism: parasitic plants and the brood parasite, which occurs in birds.

The course is completed with five lab experiments in which you learn to recognize protozoa, helminths and parasitic arthropods, and learn the techniques of treatment of feces and blood, hematological techniques and coprological techniques.


The course have five units. The first is an introduction to the world of Parasitology, the second is about protozoan parasites, third of parasitic worms or helminths, fourth of parasitic arthropods and fifth of parasitic plants and the brood parasite.

The tips for studying the various topics are as follows:

1. Read the summary as an introduction to the unit to be discussed

2. Read carefully the readings proposed in the corresponding links

3. Watch the videos to set the ideas and delve into the topics. However, these will not be subject to examination

4. Read the following diagrams and try to answer the questions that arise

5. Perform lab experiments, if not physically possible, in a virtual way

6. Expand, to the extent possible, Internet searches and / or written bibliography at the end of this guide

7. Go a lot further! At the end of this didactic guide we tell you

To obtain the Certificate of Completion, and if you wish the digital badge, of the Parasitology course you must pass the test exam with 60 questions with four alternative answers on the subjects that appear in the course program. About 15% of the issues will be related to virtual laboratory experiments. The test is passed with at least 80% of correct answers. The exam has a time limit of 60 minutes and can be repeated as many times as desired.

This is the web adress of the general post of the course, that includes the web address of the examination online to be able to obtain the certificate of completion.


Don't stop! Because it is when the Parasitology course begins. Read, learn, debate, comment, do courses, search the Internet and libraries, research and never stop learning. Remember that in today's world it changes so fast that it requires retraining and updating of knowledge.
