IMMUNOLOGY

Detailed explanation-1: -Protists are a diverse group of organisms that are either unicellular or multicellular without highly specialized tissues. They could be viewed as those eukaryotes that cannot be classified as one of the other cell types. They include the one-celled animal-like protozoa, one-celled algae, slime molds and water molds.

Detailed explanation-2: -One example is malaria, which is caused by Plasmodium, a eukaryotic organism transmitted through mosquito bites. Malaria is a major cause of morbidity (illness) and mortality (death) that threatens 3.4 billion people worldwide.

Detailed explanation-3: -Pathogenic protists are parasites that infect other organisms, like animals and human beings, and cause harm to their hosts. Some examples of pathogenic protists are Trypanosoma brucei, T. cruzi, Plasmodium falciparum, and Toxoplasma gondii. Sleeping sickness is caused by the pathogenic protist T.

Detailed explanation-4: -Pathogenic eukaryotes belong to several distinct phylogenetic lineages and have evolved the ability to colonize a range of hosts, including animals and plants. Pathogenic lifestyles have evolved repeatedly in eukaryotes, indicating that unique molecular processes are involved in host infection.

Detailed explanation-5: -Sleeping sickness and malaria are caused by protozoans which are eukaryotic organisms.

Detailed explanation-6: -19.1: Mycoses of the Skin and Eyes. 19.2: Protozoan and Helminthic Infections of the Eyes. 19.3: Respiratory Mycoses. 19.4: Fungal Infections of the Reproductive System. 19.5: Protozoan Infections of the Reproductive System. 19.6: Protozoan Infections of the Gastrointestinal Tract.
