host

 [hōst]
1. an animal or plant that harbors and provides sustenance for another organism (the parasite).
2. the recipient of an organ or other tissue derived from another organism (the donor).
accidental host one that accidentally harbors an organism that is not ordinarily parasitic in the particular species.
definitive host (final host) a host in which a parasite attains sexual maturity.
intermediate host a host in which a parasite passes one or more of its asexual stages; usually designated first and second, if there is more than one.
paratenic host a potential or substitute intermediate host that serves until the appropriate definitive host is reached, and in which no development of the parasite occurs; it may or may not be necessary to the completion of the parasite's life cycle.
host of predilection the host preferred by a parasite.
primary host definitive host.
reservoir host an animal (or species) that is infected by a parasite, and which serves as a source of infection for humans or another species.
secondary host intermediate host.
transfer host one that is used until the appropriate definitive host is reached, but is not necessary to completion of the life cycle of the parasite.

ac·ci·den·tal host

host that harbors an organism that usually does not infect it.

ac·ci·den·tal host

(ak-si-dentăl hōst)

host

1. an animal or plant that harbors and provides sustenance for another organism (the parasite). Includes paratenic, intermediate etc.
2. the recipient of an organ or other tissue derived from another organism (the donor).

accidental host
one that accidentally harbors an organism that is not ordinarily parasitic in the particular species.
alternate host
intermediate host.
dead-end host
the disease cannot be transmitted from the infected host to another animal.
host determinants
characteristics in the host which determine its susceptibility to a disease, e.g. closeness to parturition and metabolic diseases.
host-parasite reaction
the inflammatory reaction that sometimes occurs around a parasite in tissues, e.g. a warble fly larva in the esophageal wall.
predilection host
the host preferred by a parasite.
primary host
definitive host.
reservoir host
an animal (or species) that is infected by a parasite, and which serves as a source of infection for humans or another species.
host risk factors
epidemiological factors contributing to the development of a disease and which are contributed by the host.
secondary host
intermediate host.
host specificity
the characteristic of a parasite that renders it capable of infecting only one or more specific hosts.
transfer host, transport host
one that is used until the appropriate definitive host is reached, but is not necessary to complete the life cycle of the parasite.
host variable
see host determinants (above).
