Abstract: | What appeared to be the early stages in the formation of a single egg with a striated embryophore was observed in an in vitro culture of Echinococcus granulosus protoscoleces isolated from sheep hydatid cysts in North Jordan. The 'egg' measured 19 x 19 microns in diameter and was formed in an intermediate vesicular/monozoic form which was never previously reported from a culture. This is the first report of an apparently shelled egg forming in an in vitro culture, but although promising, cannot be regarded as being unequivocal and will require confirmation by further work. |
