[hōst]
(biology)
An organism on or in which a parasite lives.
The dominant partner of a symbiotic or commensal pair.
(chemistry)
A crystalline lattice or receptor molecule for the strong and selective binding of a cationic, anionic, or neutral organic, inorganic, or biological substance (guest) by means of electrostatic, hydrogen-bonding, van der Waals, or donor-acceptor interactions. Examples include clathrates, crown ethers, cryptands, cyclodextrins, calixarenes, cavitands, cyclophanes, and cryptophanes. Also known as host structure, host substance.

host

(networking)
A computer connected to a network.

The term node includes devices such as routers and printers which would not normally be called "hosts".

host

(communications)
A computer to which one connects using a terminal emulator.

host

(1) A source of information or signals. The term can refer to a computer, smartphone, tablet or any electronic device. In a network, clients (users' machines) and servers are hosts because they are both sources of information in contrast to network devices, such as routers and switches, which only direct traffic. See host adapter and hostname.

(2) To have in one's possession. When you "host a computer system," the system is running in your facility. Although sounding inane, it is technically accurate to say "our company hosts many hosts!"

Ward and Whipple (1918) state that an acridid is also a developmental host, while mosquito larvae served as experimental paratenic hosts in studies by Poinar and Doelman (1974).
Transport host An animal acting as a substitute intermediate host of a parasite; no additional development of the parasite occurs in the paratenic host; also known as a paratenic host.
Identified oligacanthorhynchid species in reptile paratenic hosts from the United States have only been recorded by Elkins & Nickol (1983) from southern Louisiana and Bolette (1997) from Nolan County, Texas.

(2000) reported that variations in the infection parameter of anisakids in fish species are related in part to the presence of definitive hosts, environmental factors, such as temperature, that influence the development of the parasite eggs, populations of intermediate or paratenic host crustaceans, as well as the age, size and feeding habits of the fish.
(2000), this fish can be considered as opportunistic and this behavior will influence the parasitism levels and species composition, since most of endoparasitic helminths present larval stages which require an intermediate or paratenic host. Moreover, this fish, that also hosts larval stages, acts as an intermediate host of parasitic species trophically transmitted.
The acanthocephalan transmission to anurans occurs by ingestion of invertebrates parasitized with cystacants that infect the gastrointestinal tract (Kennedy, 2006), making the anuran a definitive or paratenic host (Smales, 2007; Pinhao et al., 2009; Santos and Amato, 2010).
The peculiar epidemiology of Dracunculus medinensis (Guinea worm), the causative agent of dracunculiasis (Guinea worm disease), in Chad has led to speculation that a paratenic host is involved in the life cycle, most likely an animal with an aquatic stage that would feed upon copepods and harbor the infection for subsequent transmission to a human or dog definitive host (1).
CDC and The Carter Center is that the cases in humans and dogs are associated with an intense domestic and commercial fishing industry along the Chari River (where nearly all the cases have occurred) and involve a fish that serves as a paratenic host (an intermediate host in which no development of the parasite occurs).
