Symbiosis |
Any association, either temporary or permanent, between at least two living organisms of different species. (does not have to have benefits) |
|
Phoresis |
The smaller member of the relationship is carried by other organisms |
|
Mutualism |
Both organisms in the symbiotic relationship benefit from that relationship |
|
Commensalism |
One organism benefits while the other is not affected |
|
Parasitism |
one organism lives on or within the other and may cause harm. (parasite is dependent on the host) |
|
Ectoparasite |
lives on the body of the host |
|
Endoparasite |
lives within the body of the host |
|
Infestation |
ectoparasites present on the host |
|
Infection |
endoparasites present in the host |
|
Anthelmintic |
compounds that kill round worms, tapeworms, flukes, and thorny headed worms. |
|
Acaricides |
compounds that kill ticks and mites |
|
Insecticides |
compounds that kill insect species |
|
Aberrant parasite |
accidental migration of a parasite from its target area of the host to a different area. |
|
Incidental parasite |
infecting an organism not considered the typical (natural) host. (deer tick) |
|
Facultative parasite |
when a typically non-parasitic organism parasitizes a host |
|
Obligatory parasite |
organism that needs a host in order to survive (permanent or periodic) (fluke) |
|
Periodic parasite |
Does not live on the host for its entire life cycle, but needs to "visit" for nutrition or other benefits. (flea) |
|
Definitive host |
Harbors the adult (sexually mature) stage of the parasite. |
|
Intermediate host |
Harbors the immature (larval, juvenile, asexual) stages of the parasite. Can have more than one- typically transfers the parasite to the definitive host. |
|
Paratenic host |
The parasite undergoes no development (static or suspended phase, until the definitive host is reached) |
|
Hypobiosis |
Resting state, not eating or reproducing |
|
Reservoir host |
Primarily harbors the organism, usually not greatly affected by the infestation/infection, maintains the parasite population |
