accidental host  one that accidentally harbors an organism that is not ordinarily parasitic in the particular species.

definitive host , final host the organism in which a parasite passes its adult and sexual existence.

[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.

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).

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. If you've got blurrly vision becuase of a medication, you need to go see that doctor who prescribed it, and see if there is another medication that won't have side effects for you. I know everyone is different.

Welbutrin made me itch all over and the doctor changed me to something else.

The trouble with depression medication, is that its not so wise to decide by yourself to stop taking it. That's well documented.

With blurry vision, that could be unsafe for driving and can affect your work and daily activity. There are alternative medications. The side effects for one patient may not be there for others.

You can look up side effects of your particular medication on the internet right now. You might be able to find out more helpful info.
Maybe your dosage is not right?? That's doctor stuff... Go see your doctor ASAP.
