Giardia and Giardiasis Volume 107-Part B, in the Advances in Parasitology series, is dedicated to aspects of cytoskeletal structure of this parasite with an emphasis on insights of new components and their function in trophozoites. Further, microtubule function and its critical involvement in motility, attachment, mitosis and cell division as well as in transitions between developmental stages are reviewed. Also a comprehensive revision in the progress of tools to explore and understand the functional biology of Giardia, its coding and non-coding genes, features and cellular and molecular biology is contained in this volume. Additionally, an exciting perspective on the interactions between Giardia and intestinal epithelial cell by reviewing transcriptomic and proteomic investigations is included along with a state-of-the art of the understanding pathophysiology of giardiasis and of how Giardia can cause post-infectious and extra-intestinal complications. A complete review of current knowledge including commonly prescribed drugs, causes of therapeutic fails, drug resistance mechanisms, strategies for the discovery of new agents for alternative drug therapies is covered.
