[Development of D. (A.) weissi, a macroscelid's filaria, in Ornithodoros erraticus (author's transl)].

The microfilariae of D. (A.) weissi parasite of Elephantulus rozeti in North Africa evolved in Ornithodoros erraticus (Vellozo strain from Casablanca) where they reach the infective stage. The Filaria D. (A.) viteae, parasite of Gerbillid Rodents, is closely related to D. (A.) weissi but has some clear differential characters; on the contrary the infective stages seem to be undistinguishable.
