[New contribution on Dipetalonema viteae. Keeping adults alive in vitro. Scanning electron microscope study of the development of embryos and young larvae L1 and L2].

The adult stages of Litosomosoides carinii, Dirofilaria uniformis and Dirofilaria immitis have been successfully maintained in vitro though microfilaria production by the worms continued only for a period of one to 18 days. In this paper we describe the results obtained in a series of experiments in which adult L1 and L2 stages of Dipetalonema viteae were maintained in vitro.
