was the result of the efforts of Robert Cleverdon. The rapidly developing discipline of molecular biology and the rapidly expanding knowledge of the PPLO were brought together at this meeting. In addition to the PPLO specialists, the conference invited Julius Marmur to compare PPLO DNA to DNA of other organisms; David Garfinkel, who was one of the first to develop computer models of metabolism; Cyrus Levinthal to talk about coding; and Henry Quastler to discuss information theory constraints on very small cells. The conference was an announcement of the role of PPLO in the fundamental understanding of molecular biology. Looking back 40-some years to the Connecticut meeting, it was a rather bold enterprise. The meeting was international and inter-disciplinary and began a series of important collaborations with influences resonating down to the present. If I may be allowed a personal remark, it was where I first met Shmuel Razin, who has been a leading figure in the emerging mycoplasma research and a good friend. This present volume is in some ways the fulfillment of the promise of that early meeting. It is an example of the collaborative work of scientists in building an understanding of fundamental aspects of biology.

The Mycoplasmas,Volume V: Spiroplasmas, Acholeplasmas,and Mycoplasmas of Plants and Arthropods focuses on existing knowledge and recent development in research on spiroplasmas, acholeplasmas, and other mollicutes of plants and arthropods. Organized into 11 chapters, this volume discusses the nutrition, cultivation, ecology, and molecular and cellular biology of spiroplasmas. Because the occurrence of other mollicutes (mycoplasma and acholeplasma) in plant and arthropod environments is not extensively discussed in other volumes, this volume shows the rapid progress in describing the new mollicutes from arthropods and plant surface that they contaminate. Molecular studies of mollicute phylogeny and plant infections incited by the so-called mycoplasma-like organisms are also presented. This book will provide a comprehensive reference source for all mycoplasmologists and a relevant and exhaustive summary of recent advances in the study of spiroplasmas, acholeplasmas, and mycoplasmas in plant and arthropod hosts for microbiologists, cellular and molecular biologists, plant pathologists, and entomologists.

The Biology of Mycoplasmas discusses the origins, structure, significance, and dynamics of reproduction and growth of mycoplasmas. It also explains the relationship of mycoplasmas to bacteria and bacterial L-forms as well as to its chemical and physical environment. The book compares mycoplasmas with other group of microorganisms. In this way, it explains the rationale of separating this group from other groups. Aside from describing the organism and its growth and relationships, the book also explains the pathogenicity and significance of mycoplasmas as cells. It also discusses the immunological response to this group of organisms. This book will be invaluable to general biological scientist as well as to undergraduate and graduate students specializing in biology, microbiology, and other related sciences.

The Mycoplasmas, Volume I: Cell Biology is a volume of a comprehensive three-volume series encompassing various facets of mycoplasmology, emphasizing outstanding developments made in the field. This volume deals specifically with the cell biology of the mycoplasmas. This book focuses on problems regarding mycoplasma classification, phylogenetics, and relatedness to wall-covered bacteria; their unique molecular biology, energy metabolism, transport mechanisms, antigenic structure, and membrane biochemistry. The characterization, ultrastructure, and molecular biology of the mycoplasmaviruses, as well as the special properties of several groups of mycoplasmas, such as Ureaplasma, Acholeplasma, Thermoplasma, and Anaeroplasma, are also described. This book will serve as a standard reference work for mycoplasmologists, as well as for other interested microbiologists, cellular and molecular biologists, membrane biochemists, clinicians, veterinarians, plant pathologists, and entomologists.

This is a collection of cutting-edge mycoplasma methods for the detection, isolation, identification, characterization, and genetic manipulation of the pathogenic mycoplasmas. These step-by-step methods are crafted for successful reproducibility and include biochemical, genetic, and molecular techniques essential to understanding pathogenecity and adhesion to host cells. They also cover the detection of mycoplasmas in cell cultures, an important tool not only in viral diagnosis and research, but also in the production of vaccines and various biological products.

The Mycoplasmas, Volume IV: Mycoplasma Pathogenicity is a collection of essays that discusses the factors involved in recovery of mollicutes. The book presents the importance of mixed infections involving mycoplasmas and other microorganisms. It also demonstrates the importance of mycoplasmal arthritis in veterinary medicine. The text describes the dynamics and physicochemical aspects of adherence. It discusses the interaction of mycoplasmas with lymphoid cells and macrophages. Another topic of interest is the induction of cytotoxic lymphocytes by mycoplasma. The section that follows describes the chemoprophylaxis for mycoplasma diseases in man. The book will provide valuable insights for microbiologists, pathologists, students, and researchers in the field of bacteriology.

The Mycoplasmas, Volume II: Human and Animal Mycoplasmas is a volume of a comprehensive three-volume series encompassing various facets of mycoplasmology. This volume deals with host-parasite relationships of mycoplasmas in man and animals, with emphasis on recent developments in the study of classical mycoplasmal diseases of animals, such as cattle, sheep, goats, swine, and chickens. This volume shows the knowledge about mycoplasmal diseases of man, including those involving the respiratory and genitourinary tracts. Detailed information on the humoral and cellular immune responses to mycoplasmas,which are assuming an ever-increasing significance in the understandingof the pathogenesis of human and animal mycoplasmal diseases, is also given. This book ends with reviews on mycoplasmas as arthritogenic agents and the interaction of mycoplasmas with cell andorgan cultures. This book will serve as a standard reference work for mycoplasmologists, as well as for other interested microbiologists, cellular and molecular biologists, membrane biochemists, clinicians, veterinarians, plant pathologists, and entomologists.
