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.

host

[hōst]
Etymology: L, hospes
1 an organism in which another, usually parasitic, organism is nourished and harbored. A definitive host is one in which the adult parasite lives and reproduces. An intermediate host is one in which the parasite exists in its nonsexual, larval stage. A reservoir host is a primary animal host for organisms that are sometimes parasitic in humans and through which humans may become infected.
2 the recipient of a transplanted organ or tissue. Compare donor.

Patient discussion about host

Q. I was diagnosed with depression and have taken a whole host of antidepressants. I’m Mark, 29 years old male. I was diagnosed with depression and have taken a whole host of antidepressants. My eyes are extremely blurry, I’m worrying about that. Does this side effect go away with time, or is it permanent while on medications?

A. Mark, you really need to consult your doctor. I hope you're not relying totally on the Internet for medical advice. Side effects are common with most drugs, and some are more tolerable than others. "Extremely blurry" eyes seems like it could affect your driving, as cbellh47 wrote, but many other things as well.

Sometimes it does take many, many attempts to discover an anti-depressant or a combination of more than one to achieve a better mood balance. We're all chemically different and react to drugs differently. There's many options and I had to endure years of experimentation before I was satisfied, but I now have the rest of my life to appreciate what I went through.

I also used the help of different doctors and psychiatrists, as well as self-learning. If your doctor doesn't seem to be beneficial, consider asking him/her to recommend a specialist. New treatments come to light regularly and not all docotrs are wise to them.
