Web01. mar 2002. · The second major difference between digeneans and monogeneans is in the combination of their modes of reproduction and life cycles. Digeneans have asexual reproduction in a molluscan host followed by transmission to a vertebrate definitive host in which sexual reproduction occurs. WebThey have a direct life cycle and can cause respiratory disease when infecting gills, or scale loss may occur if the parasite is attached to the skin. ... The life cycle of Clinostomum complanatum Rudolphi, 1814 (Digenea, Clinostomidae) on the floodplain of the high Paraná river, Brazil. Parasitology Research, vol. 89, no. 6, pp. 506-508. http ... There is a bewildering array of variation on the complex digenean life cycle, and plasticity in this trait is probably a key to the group's success. In general, the life cycles may have two, three, or four obligate (necessary) hosts, sometimes with transport or paratenic hosts in between. The three-host life cycle is probably the most common. In almost all species, the first host in the life cycle is a mollusc. This has led to the inference that the ancestral digenean was a mollusc parasite and t… hearst castle outdoor pool
