Opistocystidae as a whole (with its three genera, Opistocysta, Trieminentia, and Crustipellis) is thus likely to be a group within Naididae.

Finally Redi, based on numberless dissections, showed the existence of variations on that basic anatomical plan, which anyway remained distinct from that of parasitic worms. Eggs, mostly embryonated third stage larvae, and various developmental stages of the worm were found in cervical nodules of a patient from Paragominas (PA, Brazil), thus proving the existence of human autoinfection [33].
