Parasites are defined as organisms that live within another organism, or host, causing the latter’s detriment by robbing them of nutrients. Several species of parasitic organisms have found a way to turn humans into their hosts. Tapeworms, roundworms, and more are widely known, being the culprits behind many cases of gastrointestinal (GI) symptoms. More-severe infections remain common, especially in poor or marginalized communities with inadequate sanitation.

In this course, the student will be introduced to protozoan parasites, nematodes, cestodes, and trematodes. As the student progresses through the course, the clinical presentation associated with each parasite will be discussed.

For optimal comprehension, the student will be required to have preliminary knowledge of molecular and cellular biology, biochemistry, histology, and physiology.

Too superficial.
By Henry L. on 27. March 2023 for Toxoplasmosis – Protozoa (CNS Infection)

This lecture was extremely superficial. Serology is not discussed and neither the nuances of treatment of the pregnant patient. Cerebral and ocular forms of toxoplasmosis were also skipped. You need to get a physician specializing in Famliy Medicine to give this leture.

A good and nice course
By Razvan S. on 13. September 2022 for Parasites

It's very well explained, but still need to be more detailed. For my parasites exam it is not suffice.
