Dipetalonema viteae is a filarial that can evoluate among hosts zoologically broadly apart (Ixodides and Argasides), but always gathered from meriones burrows. Its evolution is, on the contrary, blocked among most of the other ticks, particularly among Ornithodoros erraticus morphologically very similar to the normal vector. Our work concerns the experimental deviation of the cycle of Dipetalonema viteae, with its possible adaptability in the bosom of an intermediate of fowl tropism and a permanent host, different from a gnawing.
