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.

in·ter·me·di·ate host

, intermediary host
1. one in which larval or developmental stages occur;
2. a host through which a microorganism can pass or which contains an asexual stage of a parasite.
Synonym(s): secondary host

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).

On the secondary host take place a parthenogenetic reproduction.
Such a swimming response is typical for cercariae that infect pelagic secondary hosts, allowing them to maintain their vertical position in the water column so they can encounter potential hosts at different depths (Loy et al, 2001; Sukhdeo and Sukhdeo, 2004).
The second pertinent fact is that, although hormaphidid aphids only reproduce sexually on the primary host, the abundance, geographic distribution, and phenology of their secondary host is probably crucial to determining reproductive isolation.
The degree of population differentiation in relation to the genotype-by-environment interactions suggests that divergence onto secondary hosts from the ancestral agria cactus is ongoing and has produced the observed geographic variation in life histories.
Dogs and foxes are the primary hosts while slugs and snails are secondary hosts.
bambusee, east Asian origin, has been reported previously from the Pourthiaea villosa (Rosaceae) as primary host in Japan and Arundinaria, Bambusa, Phyllostachys, Plejoblastus (Bamboos) as secondary hosts in Japan, China, Taiwan, Indonesia, Malaysia, Australia, India, Egypt, Italy, Spain, Portugal, Hawaii and U.
Members of the genus Promuscidea are regarded as hyperparasitoids of other hymenopteran primary parasitoids and the coccids are thus their secondary hosts (Hayat, 1998).
Studies stress different characteristics of reservoirs, namely, that infections in reservoir hosts are always nonpathogenic; any natural host is a reservoir host; the reservoir must be a different species; reservoirs are economically unimportant hosts; or reservoirs may be primary or secondary hosts (14-18).
