also occurs. New outbreaks of yellow fever have occurred in Colombia and Trinidad and new outbreaks of rift valley fever have occurred in Egypt. Chapter 6, Arenaviruses: The biochemical and physical properties have now been clar ified, and they show a remarkable uniformity in the various viruses constituting the group. The possibility that prenatal infection with LCM may result in hydrocephalus and chorioretinitis has been raised. Serologic surveys have suggested the existence of Lassa virus infection in Guinea, Central African Empire, Mali, Senegal, Cameroon, and Benin, in addition to earlier identification in Nigeria, Liberia, and Sierra Leone. Chapter 7, Coronaviruses: New studies have confirmed the important role of these viruses in common respiratory illnesses of children and adults. The viruses are now known to contain a single positive strand of RNA. About 50% of corona virus infections result in clinical illness. About 5% of common colds are caused by strain DC 43 in winter. Chapter 8, Cytomegalovirus: Sections on pathogenesis of CMV in relation to organ transplantation and mononucleosis, as well as sections on the risk and features of con genital infection and disease, have been expanded. There are encouraging preliminary results with a live CMV vaccine, but the questions of viral persistence and oncogenicity require further evaluation.

Sugar chains (glycans) are often attached to proteins and lipids and have multiple roles in the organization and function of all organisms. "Essentials of Glycobiology" describes their biogenesis and function and offers a useful gateway to the understanding of glycans.

This much-anticipated third edition again consolidates the knowledge of more than twenty experts on pathogenesis of animal disease caused by various species or groups of bacteria. Emphasizing pathogenic events at the molecular and cellular levels, the editors and contributors place these developments in the context of the overall picture of disease. Pathogenesis of Bacterial Infections in Animals, Third edition, updates and expands the content of the second edition and includes cutting-edge information from the most current research. Comments on previous editions: "...highly recommended." --The Veterinary Record "...a comprehensive, complete and easy-to-use source of information." --Veterinary Microbiology "...recommended for graduate students and specialists in microbiology, pathology and infectious disease." --U.S. Animal Health Association Newsletter "...a wonderful book." --Journal of the American Veterinary Medical Association "...highly recommended." --The Cornell Veterinarian Graduate students, faculty, researchers, and specialists in microbiology, pathology, and infectious diseases will benefit from this highly-detailed and expanded edition of a popular and well-read veterinary text.

Molecular Typing in Bacterial Infections covers common bacterial pathogenic agents, with the most effective methods for their identification and classification in the light of their specific epidemiology. The book will be a valuable resource for molecular typing of infectious diseases agents encountered in both the research and hospital clinical lab settings, as well as culture collections. Each chapter provides an overview of molecular approaches to typing bacterial pathogens. Part I gives a general overview of typing methods used in the traditional microbiology laboratory in comparison to molecular methods of epidemiology. In Part II, the relative strengths and weaknesses of the different methods applicable to the specific agents of infectious diseases are emphasized. Specific emphasis is placed on recent changes and updates in molecular typing.

Established almost 30 years ago, Methods in Microbiology is the most prestigious series devoted to techniques and methodology in the field. Now totally revamped, revitalized, with a new format and expanded scope, Methods in Microbiology will continue to provide you with tried and tested, cutting-edge protocols to directly benefit your research. - Focuses on the methods most useful for the microbiologist interested in the way in which bacteria cause disease - Includes section devoted to 'Approaches to characterising pathogenic mechanisms' by Stanley Falkow - Covers safety aspects, detection, identification and speciation - Includes techniques for the study of host interactions and reactions in animals and plants - Describes biochemical and molecular genetic approaches - Essential methods for gene expression and analysis - Covers strategies and problems for disease control
