Study Notes
Infectious Diseases
- Protozoa, Platyhelminthes, Nematodes, and arthropods can cause infectious diseases in humans.
Characteristics of Protozoa
- The infective stage of Protozoa is characterized by being highly resistant to environmental stress and able to survive outside a host.
Science of Arthropods
- Medical entomology is the science that deals with arthropods of medical importance.
Common Features of Parasites
- The common feature of Platyhelminthes, Nematodes, and Protozoa is that they are all parasites.
Classification of Parasites
- Trematodes and Cestodes are types of Platyhelminthes.
- Trematodes and Cestodes are also known as flatworms.
- Protozoa are a type of single-celled organism.
Life Cycle of Protozoa
- The cyst stage in the life cycle of Protozoa is characterized by non-feeding, non-motility, and non-reproduction.
- The vegetative stage of Protozoa is distinguished from the infective stage by its ability to feed, move, and reproduce.
Test your knowledge on infectious diseases and medical parasitology including organisms like bacteria, viruses, fungi, parasites, trematodes, cestodes, and nematodes. Explore the science of organisms seeking shelter and nourishment within living organisms.
