"In this 5th edition, therefore, we have attempted to reduce repetition, clarify, by removing some of the less important parasites, and to divide the material more clearly into two parts. The first is a taxon-based overview of the biology of key parasites of veterinary importance, their life cycles, morphology, diagnosis and identification along with the general principles of treatment and epidemiology. The second, contains specific clinical details of the pathogenesis, epidemiology, control and treatment of individual parasite species, still structured by host and organ-system. The result, we hope, is an edition that is easier to navigate for readers"-- Provided by publisher.
