This fully up-to-date book covers all aspects of Acanthamoeba biology. Following the success of the first edition, the author has extensively revised and expanded the text to produce a new volume that includes all the latest research and information on every aspect of this organism. There is a particular emphasis on the Acanthamoeba genome sequence and the novel insights gained from the application of molecular methods to Acanthamoeba developmental/cellular biology, in terms of metabolism and morphogenesis, classification, ecology and role in the ecosystem, host-pathogen interactions, virulence factors and immunological basis of pathogenesis, clinical manifestation, diagnosis, treatment, new target development, and drug resistance and its interactions with other microbes in the environment. The book will be an essential reference text for parasitologists, microbiologists, immunologists, and physicians in the field of basic and medical microbiology, as well as an invaluable reference for new and experienced researchers who wish to better understand this organism.
