The book "Parasitology and Immunology of Cystic Echinococcosis" offers a comprehensive analysis of the parasitological and immunological aspects of cystic echinococcosis, an infection caused by the larval stage of Echinococcus granulosus. This disease poses a significant health problem in both developing countries and industrialized nations. The work highlights the development of the parasite into hydatid cysts in various organs of intermediate hosts and the incidental infection of humans. It provides detailed documentation of the early developmental stages of E. granulosus as well as the mechanisms by which the parasite evades the host's immune system. Furthermore, it thoroughly discusses the protective immune responses of the host that arise during the infection, as well as the physiological and immunological mechanisms that lead to either an established or abortive infection.
