Parasitology Opposite Flashcards
(32 cards)
An association between two organisms of different species in which both are benefitted; example, tick birds in the rhinoceros
Mutualism
A parasite that makes short visits to its host to obtain nourishment or some other benefit
Periodic parasite
A relationship in which the smaller member of the relationship is mechanically carried about by the larger member; for example, bacterium being carried on legs of face fly
Phoresis
Any disease that is transmissible from lower animals to human beings
Zoonosis
The first host parasitized by the larval stages of the parasite
First intermediate host
The host that harbors the adult, sexual, or mature stages of the parasite
Definitive host
The second host parasitized by the larval stages of the parasite
Second intermediate host
Parasite that can infect a wide variety of host
Euryxenous parasite
The development of a parasite through its various life stages
Life cycle
Parasitism by an external parasite
Infestation
An intermediate host in which the parasite does not undergo any further development, usually remaining attached until the definitive host eats the transport host
Transport (or paratenic) host
An object that is mistaken for a parasite
Pseudoparasite
A short term relationship in which one symbionts benefits at the expense of the other; example the tiger and the water buffalo
Predator-prey
A parasite that lives within the body of the host
Endoparasite
An association between two organisms of different species in which one organism injures the other and produces outward signs of disease
Parasitosis
A parasite that has wandered into an organ or tissue in which it does not ordinarily live
Erratic (or aberrant parasite)
Parasite that requires two or more hosts
Heteroxenous parasite
An association between two organisms of different species in which one organism is potentially pathogenic, but does not cause outward signs of disease.
Parasitiasis
An organism that must live a parasitic existence
Obligatory parasite
A parasite that has a narrow host range
Stenoxenous parasite
An association between two organisms of different species in which one partner is benefitted and the other is neither benefitted nor harmed; sharks and remoras
Commensalism
A parasite that lives on the outside of the body of the host
Ectoparasite
A parasite that only has one type of host
Homoxenous (monoxenous)
A vertebrae host in which a parasite (or disease) occurs naturally and which is a source of infection for human beings and their domestic animals, as the case may be
Reservoir host
