Digenean trematodes

Abstract

Concluding remarks: Digenean trematodes are characteristic parasites of small mammals all over the world. In spite of the availability of faunistic data, it seems that still many species remain to be described. In particular, the use of molecular techniques and ultrastructural data of the spermatozoon and the spermiogenesis will undoubtedly help toward this end. The details of the life cycles of many species of trematode parasites of micromammals are still unclear, although some species have been thoroughly studied using experimental models. The relationships between a variety of host-related and environmental-related factors and the populations and communities of digenean trematodes also require further investigations.
