Study Notes
Parasitism Overview
- An organism that lives at the expense of another is called a parasite.
- The study of parasites is known as parasitology.
Types of Parasites
- Endoparasites are examples of parasites that live inside their host.
- Parasites that must spend at least part of their life cycle in or on a host are called obligate parasites.
- Once a parasite has invaded a host, it is considered a permanent parasite, as it remains within or on the host.
- Ectoparasites are those that live on the exterior of the host.
Parasite Transmission and Vectors
- A vector that transmits a parasite to a new host without the parasite undergoing any part of its life cycle during transit is known as a mechanical vector.
- An organism that carries other parasites and also acts as a temporary parasite itself is termed a hyperparasite.
Host Interactions
- Host specificity refers to the range of different hosts that a parasite can occupy, indicating how specialized or generalist a parasite is in its choice of hosts.
- Heteroxenous parasites invade organisms other than their typical hosts, showcasing adaptability in their host selection.
