Knowledge in the field of parasitology must be kept at a high level and up to date in order to fight a parasitosis as quickly and effectively as possible. This work, one of Springer's renowned and authoritative Major Reference Works, contributes to these goals in several ways. First, it comprises a number of entries, consisting of both in-depth essays and definitions. Secondly, the content has been improved even more by adding additional tables and high-quality figures. Thirdly, the extensive linking between definitions and essays facilitates information within a minimum of time. The Encyclopedia of Parasitology contains clearly structured essays in alphabetical order with extensive cross-references between definitions and related entries. International contributors, who are well-known specialists in their fields, give a comprehensive review of all parasites and therapeutic strategies in veterinarian and human parasitology. This 4th edition presents all important parasites of humans and animals in detail and the less important ones in short. Each parasite has its own large “chapter” with all subheadings (life cycle, morphology, treatment etc.). Topics common for other parasites and/or transmitted agents of diseases are presented in separate topics, which altogether are listed alphabetically. Furthermore all important parasitological and medical terms are explained as separate topics and are cross-linked to the chapters/topics, where they are explained intensively. Existing entries are updated and presented in the light of the latest knowledge.
