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
