Argas Ar·gas (är'gəs, -gās')
A genus of ticks that includes some species that usually infest birds but that may infect humans.
About six other species of argas from various parts of the world, parasitic on birds and mammals.
The argas reflexus lives on pigeons, and is allied to the Ixodes.
Gerstaecker states that the argas Persicus is very annoying to travellers in Persia.
When the spirochtes are ingested by argas persicus, some of them pass through the gut wall into the cœlomic fluid.
