The second edition of this important book summarizes and synthesizes our knowledge of the basic features of the development and transmission of the parasitic nematodes of vertebrates. Coverage has been expanded to include relevant data from some 450 new references, which appeared since the compilation of the first edition, published in 1992. The volume is unique in its comprehensive coverage (595 species are reviewed) and includes nematode parasites of humans, domestic animals and wildlife including fish. It provides an historical and unified overview of a century and a half of research on the development, life cycles, transmission and evolution of the nematodes found in vertebrates throughout the world.
