Examples from the Web for autosite
The Polypnathus is a parasite attached to the jaw of the autosite.
When an omphalosite exists, the other foetus is called, in this case also, the autosite.
The autosite can feel when the parasite is touched, and in some cases the autosite can localise the touch.
Parasites are nourished through the blood supply of the autosite, and the parasites usually are incapable of motion.
The Heteralitis is a second species, in which the parasite is inserted at a distance from the navel of the autosite.
