This book serves as a comprehensive yet concise reference guide reviewing the latest knowledge on bacterial, viral, fungal and parasitic infectious diseases of old world dromedary camels. Pathogen etiology, clinical manifestations and diagnostic techniques are provided for each pathogen and disease prevention and treatment strategies are discussed. Despite a steady increase in camel husbandry worldwide, the pathologies of camel diseases are still relatively under investigated in comparison to other livestock and companion animals. With an ongoing worldwide prevalence increase, infectious diseases are a constant threat to animal and human health. In recent years dromedary camels have become a focus of increasing public health interest since they have been considered the direct source of zoonotic transmission of MERS-CoV to humans. Along these lines, the book covers topics related to zoonotic infections associated with camels. This book offers a valuable source of information for veterinary clinicians, researchers, graduate students, veterinary technicians and interested laymen.

Macrocyclic lactones are chemical compounds that represent the main treatment for parasitic diseases of animals, not only for helminth infections, but also a number of major ectoparasitic infestations. There has been no comprehensive book on this subject for more than a decade and this book fills this gap and provides detailed coverage of the basic science of these drugs and their mode of action, as well as their clinical use in farm and companion animals and in humans.

Essentials of Veterinary Parasitology provides an up-to-date resource for students and practicing veterinarians on how to recognize, diagnose, and treat parasitic diseases in livestock and companion animals.

Further, the book reviews various measures for controlling viral zoonoses and examines novel therapeutic and prophylactic strategies. Discussing recent studies on the pathogenesis and host immune response to these infections, it underscores the importance of using vaccines against these viral diseases to reduce the risk of them being transmitted to humans.Lastly, it describes in detail the challenges posed by these viral infections and our readiness to face them.

This book is a comprehensive overview of the fungi that are clinically relevant for animals and humans. It is divided in three major parts: the first part comprises the history of veterinary and medical mycology, general aspects of morphology, growth, nutrition, reproduction and classification of fungi. In the second part, the etiologic agents of cutaneous, subcutaneous and systemic mycoses are described in detail with special emphasis on emerging and uncommon pathogenic fungi. Each chapter consists of a brief history and the morphology, classification, reproduction, susceptibility to disinfectants, natural habitat, distribution, genome, isolation, growth and colony characteristics, antigenic characteristics, virulence factors. The major diseases and their routes of transmission, pathogenesis, immunity, diagnosis and treatment are also covered. The third part focuses on laboratory diagnosis including clinical sample collection, their processing for fungal isolation, special stains for microscopic visualization, culture media composition and a relevant glossary. Each chapter includes color photographs, schematic diagrams and tables for better understanding.

This book offers a timely and comprehensive review of essential research on Peste des Petits Ruminants Virus (PPRV), ranging from its historical distribution, molecular epidemiology, genome structure, viral proteins, immunity, viral pathogenesis, clinical and molecular diagnosis to advances in vaccine developments and future challenges. PPRV, a Rinderpest-like virus, is the causative agent of one of the most rapidly emerging viral diseases among domestic small ruminants, and the host spectrum has now been expanded to wild small ruminants and camels. With the global eradication of the first livestock disease, Rinderpest, attention is now turning to repeating the procedure for PPR. Each of the book's 13 chapters is dedicated to a specific topic, providing up-to-date literature and discussions by renowned scientists who have made seminal contributions in their respective fields of expertise. Special emphasis has been placed on the analysis of different global efforts to eradicate PPR. This book offers a valuable reference source for virologists, field veterinarians, infection and molecular biologists, immunologists, scientists in related fields and veterinary school libraries.

This volume reviews the current understanding of the taxonomy, disease syndromes, genetics, biology, and pathogenic factors of Histophilus somni, as well as the host immune response to this pathogen. H. somni is one of the most important bacterial pathogens in cattle and other ruminants, and its virulence factors are highly conserved with Haemophilus influenzae and other members of the Pasteurellaceae. H. somni has been recognized as a major cause of thrombotic meningoencephalitis, respiratory disease syndromes, myocarditis, reproductive disease syndromes, polyarthritis, mastitis, ocular disease, and septicemia. The only known habitats of H. somni are the mucosal surfaces of ruminants, making this bacterium an opportunistic pathogen. Although it is capable of causing inflammation at systemic sites and is toxic to epithelial and phagocytic cells, the bacterium's wide array of virulence factors act primarily as a defense against, or to escape recognition from, host innate and adaptive immunity.

This volume covers the fields of origin, evolution and phylogenesis from prokaryotic to eukaryotic cells. The eminent authors, experts in their fields, review the three kingdoms of life (Archea, Eubacteria and Eukarya) from molecular evolutionary levels to ecological aspects in enigmatic habitats, including general reviews of puzzling pro-and eukaryotic organisms and their domains. We discuss dry habitats, thermophilic (cells in hot springs and undersea thermal vents up to 110AC), psychrophilic (cryophiles) and halophilic (high salt concentrations) niches which among the harshest conditions found on Earth where microbial life is frequently detected. Some chapters deal with the organisms which grow in extreme pH conditions (acidity vs. alkalinity), and under hydrostatic pressure in the deep sea, and microbial growth on petroleum. Other contributors present their research on aerobiology and microbes growing in various gases and various levels of radiation, including cellular morphological modification in these extremophilic microbes. This volume also includes the symbiotic association between two or more organisms on the endocellular and exocellular levels. Finally one paper identifies the extremophiles as candidates for exobiology. This is a valuable comprehensive volume in English that covers most of the extremophiles in a new light with current research data. Audience: Students, lecturers and researchers; scholars in the fields of biology, evolutionary biology and chemistry, and other evolutionary fields, and the intelligent layman.

Most of the chapters of this book were written during 1987 which was the Diamond Jubilee year of the publication of the first reports of Newcastle disease in 1927. During the intervening years the nature of the Poultry Industry throughout the World has changed, or is in the process of changing, dramatically from one based on small village or farm flocks, frequently kept as a sideline, to an industry based on large flocks, sometimes consisting of hundreds of thousands of birds, run by multinational companies. To all these flocks, both large and small, Newcastle disease poses a considerable threat to their well-being and profitability and it is not unreasonable to state that hardly a single commercial flock of poultry is raised in the world without Newcastle disease having some effect due to actual disease, prophylactic vaccination or restrictions placed on rearing, movement, processing, sale or export of birds and products. In addition, recent years have produced developments in virology and associated biological technology which would have been unbelievable when Newcastle disease virus was first isolated. The economic importance of Newcastle disease virus and its use as a laboratory model has meant that major advances have been quickly applied to the field situation whenever possible and, as a result, a much fuller understanding, not only of the biochemistry and basic virology of the virus but also the ecology, epizootiology, antigenicity, immunology and other important aspects in the control of the disease has been achieved.

Rabies is an ancient disease and a fearsome one. Although it may not have the economic or public health importance of some other infectious diseases, few are so well known or carry the same emotional impact. Mainly transmitted by the bite of an enraged animal, and with practically no hope for recovery among those afflicted, it has provided the substance of stories and legends throughout the ages. The pioneering work of many 19th century workers, culminating in the development of the first rabies vaccines by Louis Pasteur, provided the ground work for the modern era in the study of rabies. Since then, and particularly in the last quarter century, considerable advances have been made in our knowledge of the nature of the infectious agent, its mode of transmission and pathogenetic mechanisms. Yet even today, much remains to be learned about the disease. For example, although effective vaccines exist for humans and other animals, there is still no known practical cure once the neurological disease symptoms develop. Markers of virulence have been mapped at the molecular level, but it is yet unclear as to how rabies virus actually exerts its pathological effects.

The influence of basic science, particularly molecular biology, in human and veterinary medicine revolutionized thinking in many aspects and changed fundamentally and creatively the classical strategy for research and prevention of infectious diseases. Genetic engineering and related disciplines have progressed to a remarkable degree over the last decade and now form the keystone supporting medicine. These are strong and efficient instruments for health and disease oriented research and their application gives the opportunity to receive more answers and not only more questions. The prime objective of this book is to create new knowledge within the medical disciplines and inspire colleagues working in this field with the unity and unambiguous importance of this science and its technologies for identifying, clarifying and planning new strategies for curing and preventing disease. This book contains original studies on the molecular biology of animal viruses. Some of the viruses discussed in this book are also hazardous to man. In this light it can be considered as a contribution to modern education on the human infectious diseases. From this point of view the book contains a chapter on Hantaan virus that causes no detectable disease in animals but hemorrhagic fever with renal syndrome has been attributed to infection of humans by this virus.

G. Petursson and Rikke Hoff-J0rgensen The concept of slow viral infections was first put forward in 1954 by Dr. Bjorn Sigurdsson, an Icelandic physician who had been studying some sheep diseases which were introduced into Iceland with the importation of a foreign breed of sheep in 1933. Sigurdsson's main criteria for defining slow infec tions were a very long initial period without clinical signs lasting months or even years following infection and a rather regular protracted, progres sive course, once clinical symptoms had appeared, usually ending in serious disease or death. Sigurdsson included in this list of slow infections maedi -visna, infectious adenomatosis of sheep, scrapie in sheep, Bittner's mam mary carcinoma and Gross' leukemia in mice. All of these diseases, except scrapie, are caused by retroviruses. The characteristics of slow infections as described above are of prac tical importance for epidemiology, diagnosis and control of these diseases. For many years the slow infections remained primarily a veterinary problem, mainly affecting sheep and goats in certain countries. In recent years, how ever, the human immunodeficiency virus (HIV) causing acquired immunodefici ency syndrome (AIDS), has suddenly appeared in many countries of the world and brought the slow infection concept forcefully to the attention of the medical profession. The disease problems and the economic effects of slow infections of sheep and goats are increasingly recognized in various coun tries. For the reasons stated above we feel that this book should be useful for veterinarians and physicians alike."

The intention of the series Developments in Veterinary Virology is to provide monographs dealing with the major animal viral diseases. Each volume will include the latest achievements in fundamental research and practical applications and should be readable for people from various disciplines and different backgrounds. The multi-author approach provides the best opportunity to keep each chapter at the highest level and makes the composition of the volumes manageable to the editors. This monograph on Avian Leukosis presents comprehensive reviews on the recent history of avian retrovirus research, on epizootiological, virological, pathological aspects, on tumor induction, the immune response to avian retro viruses, virus-cell interactions and on techniques for diagnosis. The volume deals mainly with exogenous avian leukosis virus (ALV) infections, but one chapter is entirely devoted to endogenous avian leukemia virus. Molecular biology aspects are confined to various oncogenes and to lymphoma induction since retroviruses, including those specific for avian species, have recently been described in detail in the Cold Spring Harbor Laboratory series "Molecular Biology of Tumor Viruses." Two chapters are devoted to the practical application of insights obtained from avian leukosis research: influences of AL V infection on production performance and eradication procedures."

The study of animal viruses contributes to the general understanding of the molecular basis of viral infection. The emergence of the SARS (Severe Acute Respiratory Syndrome) virus in the human population, coming from an animal source, highlights the importance of animals in harboring infectious agents. In addition, it has been recognized recently that influenza viruses, which persist in their natural avian host, can directly infect humans. In this book, an international panel of leading virologists provide a state-of-the-art overview of the field, comprehensively detailing the current understanding of viruses, their replication, evolution, and interaction with the host. The authors emphasize strategic and methodological aspects of current research, and provide key related references. Topics include foot-and-mouth disease virus, Pestivirus, Arteriviridae, Coronaviruses (including SARS), Herpesviridae, Paramyxoviridae, influenza viruses, Reoviridae, porcine circoviruses, Asfarviridae and much more.

Ticks of Trinidad and Tobago: An Overview explores tick species prevalent in Trinidad and Tobago (T&T), their distribution, associated pathogens, their effects on the host, and control methods. The book also reviews the basic biology of ticks. Ticks are known to parasitize a wide range of hosts including mammals, reptiles and birds. These parasites are of veterinary and public health significance since they are responsible for the spread of a number of pathogens to humans and animals. Worldwide, ticks are responsible for billions of dollars in losses in the livestock industry annually due to the effects of these pathogens. Based on review of the literature from more than five decades, twenty-three species of both hard and soft tick have been discovered on the twin-island republic with a greater number of species in Trinidad. Tick genera observed and recorded included Argas, Ornithodoros, Amblyomma, Dermacentor, Haemaphysalis, Ixodes, and Rhipicephalus species. The tick species found in Trinidad and Tobago parasitize both wild and domestic species. Hosts include bats, fowl, equids, wild and domestic ruminants, birds, rodents, marsupials, and a variety of reptiles such as toads, tortoises, and snakes. Based on geographical location, most tick species discovered in T&T have also been recorded in other Caribbean islands in the archipelago, North, Central and South America. Both soft and hard tick species found in T&T have also been implicated in a number of blood-borne pathogens including Borrelia, Ehrlichia, Babesia, Hepatozoon, Rickettsia, and Anaplasma.
