Document Summary
Affect more than 1. 8 billion people (mostly in africa), including 500 million people. Parasites can be classified in many different ways, based on complexity, appearance, phylogenetics, and many others. The classification of parasites is constantly evolving, as we learn more about them. For the purposes of these lectures, we are going to use the largest and easiest distinction size. Parasites can be classified into: subkingdom protozoa, which are single cell organisms, subkingdom metazoa, which are large, multicellular organisms. Going to start with protozoa, focusing on malaria. Protozoa can be separated into 4 distinct phyla, each of which has members of significance to humans. The disease malaria is caused by a parasite called plasmodium. There are 4 different plasmodium species that can infect humans and cause varying severities of malaria: p. falciparum (most severe, p. vivax, p. ovale, p. malariae. Malaria presents with a high fever, chills, flu-like symptoms and anemia.
