General Principles of Parasitology Flashcards
Concerned with the phenomenon of dependence of one living organism on another.
Parasitology
Parasites that affect humans and human health, as well as their importance in human communities.
Medical Parasitology
An illness that is endemic in tropical areas like the Philippines.
Tropical disease
Name the 4 types of Biological Relationship
- Predation
- Competition
- Cooperation
- Symbiosis
A type of biological relationship where two organisms have close and long-term biological interaction.
Symbiosis
A type of biological relationship where one organism kills and eats another organism.
Predation
A biological relationship where there are two or more organisms working together for common benefit.
Cooperation
A biological relationship where two or more organisms strive for a resource like food, which cannot be shared.
Competition
Name the 3 types of Symbiotic Relationship
- Commensalism
- Mutualism
- Parasitism
A type of symbiotic relationship where species A and B receive benefits from one another.
Mutualism
A type of symbiotic relationship where species A receives benefits, while species B is harmed.
Parasitism
A type of symbiotic relationship where species A receives benefits, while species B is not affected.
Commensalism
It is an organism that is often described according to its habitat or mode of development.
Parasites
There are 9 types of parasites identified, name at least 5 parasites.
- Endoparasite
- Ectoparasite
- Obligate parasite (holoparasite)
- Facultative parasites
- Accidental or incidental parasite
- Permanent parasite
- Temporary parasite
- Erratic parasite
- Sporious parasite
Type of parasite that is free-living and passes through the digestive tract without infecting the host.
Spurious parasite
Type of parasite that is found in an organ that is not its usual habitat.
Erratic Parasite
A parasite that lives on the host for a short period of time.
Temporary parasite
A parasite that establishes itself in a host where it does not ordinarily live.
Accidental or Incidental Parasite
Parasite that remains in or on the body of the host for its entire life.
Permanent parasite
A parasite that may exist in a free-living state or may become parasitic when the need arises.
Facultative parasite
A parasite living inside the body (internal organs/tissues) of a host.
Endoparasite
A parasite living outside on the surface of the body of a host.
Ectoparasite
A parasite that requires a host at some stage of their life cycle to complete their development and propagate their species.
Obligate parasite (Holoparasite)
Name the five types of host.
- Definitive or final host
- Intermediate host
- Paratenic host
- Reservoir host
- Incidental host
A type of host in which the parasite does not develop further to later stages. The parasite remains alive and can infect another susceptible host.
Paratenic host
A type of host in which the parasite attains sexual maturity.
Definitive or final host
A type of host in which though infected is not necessarily for the survival or development of the parasite.
Incidental host
A type of host in which is harbors the asexual or larval stage of the parasite.
Intermediate host
A type of host that is infected by a parasite, and serves as a source of infection for humans or another species.
Reservoir host
It is responsible for transmitting the parasite from one host to another.
Vectors
Name two types of vectors
- Biological Vector
2. Mechanical or phoretic vector
