Study Notes
Ectoparasites vs. Endoparasites
- Ectoparasites live on the surface of a host, while endoparasites live inside the host's body.
- Endoparasites can cause more severe damage due to their intimate association with host tissues.
Dependency on Host
- Obligate parasites are entirely dependent on their host for survival during a segment or all of their life cycle.
Accidental Parasites
- Accidental parasites are organisms that invade hosts other than their normal hosts, often leading to unpredictable consequences.
Facultative Parasites
- Facultative parasites can adapt to a parasitic lifestyle but are not entirely dependent on it; they can live independently in the environment.
Erratic Parasites
- Erratic parasites are those that wander from their usual site of infection, often leading to unusual sites in the host's body.
Importance of Opportunistic Parasites
- Understanding opportunistic parasites is crucial due to their potential to exploit weakened host defenses and cause disease under certain conditions.
Definitive Host
- A definitive host is one where the parasite undergoes sexual reproduction, completing its life cycle.
Transport Host
- A transport host, or paratenic host, provides a temporary refuge and serves as a vehicle to reach the definitive host.
Mutualistic Relationship
- In a mutualistic symbiotic relationship, both partners are metabolically dependent on each other for survival and benefits.
Commensal Relationship
- In a commensal relationship, one partner benefits while the other is not significantly harmed or helped.
Reservoir Host
- A reservoir host makes the parasite available for transmission to another host, typically without suffering from the infection.
Symbiont
- A symbiont is an organism that spends a portion or all of its life cycle attached to or intimately associated with a different species.

Description
Learn about different kinds of parasites including ectoparasites (living on the outer surface), endoparasites (living inside the host), obligate parasites (completely dependent on the host), and facultative parasites (exhibiting both parasitic and non-parasitic modes of living).
