Trematoda - Study guides, Class notes & Summaries

General characteristics: 1.The class trematoda falls into two main subclasses, the Monogenea, which have a direct life cycle, and the Digenea, which require an intermediate host, are of medical significance 2. The adult digenetic trematodes, commonly called `flukes', occur primarily in the bile ducts, alimentary tract and vascular system. 3. Most flukes are flattened dorsoventrally, have a blind alimentary tract, suckers for attachment 4.Depending on the predilection site, the...
