The plan for this atlas evolved from the necessity of providing the biology student interested in protozoology, cytology, and para sitology with an introduction to the study of fine structure in Protozoa. To reduce the book's extend, a selection of characteristic protozoans had to be made, limited to those which could be regarded as representative for entire groups. Interest in parasitic protozoans has been steadily on the increase over the last 10 years. This particular group of organisms thus seemed a very suitable choice. The" Apicomplexa" were selected as an area of emphasis. These once were part of the collective group called Sporozoa which included many parasitic protozoans of uncertain taxonomy. Fine structural research has been of especial significance for the Apicomplexa, since Protozoa belonging to this subgroup can now be named, characterized, and classified by features recognizable by electron microscopy. Only the fine structure of whole cells is represented in this atlas, so that the ciliates have been of necessity excluded. Their cells are too large in diameter in any case for our purpose here. They also play only a minor role as parasitic organisms. This book utilizes a new method to facilitate the analysis of protozoan fine structure. An electron micrograph, a descriptive text, and an analytic drawing are arranged on two facing pages so that the electron micrograph and the drawing can be compared.

Intracellular Parasitic Protozoa introduces the basic structure and classification of intracellular parasitic protozoa and the concept of parasitism. This book starts by discussing the concept of parasitism and the taxonomic background of various intracellular protozoan organisms. This is followed by a description of the relationships between intracellular protozoan and their host cells. Then, this book discusses the ultrastructure of cells and organisms, emphasizing cell morphology that serves as the primary basis of generalizations of the host cell-parasite relationships. It also presents the intracellular protozoa in several groups according to their probable taxonomic relationships and more obvious morphological similarities. Finally, this text describes protozoan fine structure, along with a brief discussion of their biological aspects. This book is ideal for researchers, teachers, and students who wish to gain more knowledge in parasitism caused by intracellular protozoa.

Updated and much expanded, the Second Edition of Parasitic Protozoa is designed to be useful to physicians, veterinarians, and research scientists concerned with diseases caused by protozoa in man, and in domestic and wild animals including fish, mollusks and insects, as well as the more commonly considered vertebrate animals. Each section contains information on disease pathogens, treatment, diagnosis, and epidemiology of the diseases caused by the various protozoans. The book is not limited to these medically-oriented subjects, but treats taxonomy, morphology, and metabolism of the organisms in such a way as to be of interest to scientists and graduate students working in the field of protozoology. The entire edition, published in ten volumes, is arranged so that subjects of common interest occupy individual volumes.

The protozoa are an eclectic assemblage of organisms encompassing a wide range of single-celled and multiple-celled colonial organisms lacking tissue organiza tion, but exhibiting remarkably refined biological behavior. In some modern classifications, they are classified as a subkingdom among the Protista (eukary otic single-celled organisms). Although they are not considered a formal cate gory by some taxonomists and some biologists consider the name inappropriate (inferring that they are the first unicellular animals, although some photosynthe size), it is still convenient to consider this group of organisms as an informal collection under the heading of protozoa. Their cosmopolitan distribution, sig nificant ecological role in mineral recycling and enhancement of carbon flow through lower trophic levels of food webs, and remarkable cellular adaptations to enhance survival in diverse environments make them significant organisms for biological investigation. In some cases, biologists are introduced to this group in first level courses or in invertebrate zoology, but never develop a full appreciation for the diverse and biologically sophisticated characteristics of these organisms. This book is intended as a survey of broad concepts in protozoan biology with an emphasis on comparative data. The focus is on the zoological aspects of the group. Topics more closely related to plantlike characteristics, as presented in books on phycol ogy, are not considered in detail here. A sound background in modern biology and an introduction to cellular biology will be helpful in understanding Chapters 15 and 16, which include a substantial amount of information on biochemistry.

It is now 17 years since the junior author's book Parasitic protozoa was first published, and 13 years since it received limited revision. The study of symbiotic protozoa has meanwhile progressed, and much of the content of the earlier book has been superseded if not displaced by recent knowledge. We believe that there is still a place for an introductory textbook, conventionally arranged on a taxonomic frame work, on this most fascinating group of organisms. It should supplement (certainly not supplant) more modern treatments from different angles. A mountain looks very different if one approaches it from different sides, though a true picture of that mountain can be built up only by the laborious summation of the views provided by all approaches. The immunology and the chemotherapy of protozoal infections are subjects so complex that we do not propose to try to encompass them in this book. We mention briefly the more commonly used therapeutic compounds in the various chapters that follow, without giving details of dosage schedules. Further information on immunology and chemo therapy can be obtained from the books listed at the end of the Introduction; the information we give on chemotherapy is largely drawn from that of James & Gilles. This book can be regarded as an evolutionary descendant of the earlier "Parasitic protozoa", referred to above, extensively revised and much more fully illustrated. We hope that it will prove as useful as its predecessor appears to have been.
