Study Notes
Medically Important Parasites
- Medically important parasites are primarily eukaryotic organisms with a membrane-bound nucleus.
- They are divided into two big kingdoms: Kingdom Animalia and Phylum Nematoda.
- Phylum Nematoda includes parasites commonly referred to as roundworms, with general morphology resembling a prototypical worm and a complete digestive tract.
- Members of Phylum Nematoda include Ascaris, Trichuris, Hookworms, and Strongyloides.
- Phylum Platyhelminthes includes Class Cestoda and Class Trematoda, with distinct characteristics such as tapeworms being dorsoventrally flat and hermaphroditic.
- There are many genera of arthropods that can be considered human parasites, including cockroaches, caterpillars, hornets, and wasps.
- Most parasitic arthropods are ectoparasites and vectors for other parasites, belonging to the classes of insects and arachnids.
- Phylum Apicomplexa includes obligate intracellular parasites possessing an apical complex to help infect the host cell, with members such as mosquitoes, lice, and ticks.
- Phylum Sarcomastigophora/Coccidia includes ameboid protozoans in trophozoite stage, with members like Toxoplasma, Cryptosporidium, and Cyclospora.
- Phylum Ciliophora includes ciliates with a general morphology resembling an amoeboid, asymmetric shape and a locomotory apparatus of cilia.
- Phylum Hemosporidia includes organisms studied in medical parasitology as indicator organisms.
- The text provides detailed information on the taxonomy, morphology, and characteristics of medically important parasites and their respective classifications.
