Book Description
While the focus of the first edition was on sub-Saharan Africa, this second edition has significantly expanded contents that include the majority of the infectious diseases of livestock that occur world-wide. Each of the infectious diseases is dealt with in terms of its introduction and history, epidemiology, pathogenesis, clinical signs, pathology, diagnosis, differential diagnosis, and control. A comprehensive list of references is provided for each disease. To facilitate readability, references are numbered in the text.

Book Description
Most of the important infectious diseases that threaten livestock--including heartwater, bluetongue, African horse sickness, African swine fever, babesiosis, anaplasmosis, and trypanosomiasis --occur endemically on the Southern African subcontinent and are responsible for major stock losses annually. Infectious Diseases of Livestock offers a comprehensive overview of the factors which influence the occurrence of such diseases, focusing in particular on arthropod vectors (ticks, tsetse flies, culidoides midges, mosquitoes, and biting flies), herd immunity and immunization strategies, resistance of animal breeds to infectious agents and their vectors, and the role played by wild animals in the spread of infectious diseases. Throughout, diseases are grouped according to their causal infectious agents and are treated in terms of their history, epidemiology, pathogenesis, clinical signs, pathology, diagnosis, differential diagnosis, and control. The book concludes with a discussion of diseases of unknown etiologies and important disease complexes such as mastitis and congenital viral teratology. Well-written and completely up-to-date, this book is the reference that students, professionals, and researchers in infectious diseases, pathology, tropical medicine, and veterinary research have been waiting for

Book Description
This open access volume presents a comprehensive account of all aspects of biological invasions in South Africa, where research has been conducted over more than three decades, and where bold initiatives have been implemented in attempts to control invasions and to reduce their ecological, economic and social effects. It covers a broad range of themes, including history, policy development and implementation, the status of invasions of animals and plants in terrestrial, marine and freshwater environments, the development of a robust ecological theory around biological invasions, the effectiveness of management interventions, and scenarios for the future. The South African situation stands out because of the remarkable diversity of the country, and the wide range of problems encountered in its varied ecosystems, which has resulted in a disproportionate investment into both research and management. The South African experience holds many lessons for other parts of the world, and this book should be of immense value to researchers, students, managers, and policy-makers who deal with biological invasions and ecosystem management and conservation in most other regions.

Book Description
Pathogens transmitted among humans, animals, or plants by insects and arthropod vectors have been responsible for significant morbidity and mortality throughout recorded history. Such vector-borne diseases â€" including malaria, dengue, yellow fever, and plague â€" together accounted for more human disease and death in the 17th through early 20th centuries than all other causes combined. Over the past three decades, previously controlled vector-borne diseases have resurged or reemerged in new geographic locations, and several newly identified pathogens and vectors have triggered disease outbreaks in plants and animals, including humans. Domestic and international capabilities to detect, identify, and effectively respond to vector-borne diseases are limited. Few vaccines have been developed against vector-borne pathogens. At the same time, drug resistance has developed in vector-borne pathogens while their vectors are increasingly resistant to insecticide controls. Furthermore, the ranks of scientists trained to conduct research in key fields including medical entomology, vector ecology, and tropical medicine have dwindled, threatening prospects for addressing vector-borne diseases now and in the future. In June 2007, as these circumstances became alarmingly apparent, the Forum on Microbial Threats hosted a workshop to explore the dynamic relationships among host, pathogen(s), vector(s), and ecosystems that characterize vector-borne diseases. Revisiting this topic in September 2014, the Forum organized a workshop to examine trends and patterns in the incidence and prevalence of vector-borne diseases in an increasingly interconnected and ecologically disturbed world, as well as recent developments to meet these dynamic threats. Participants examined the emergence and global movement of vector-borne diseases, research priorities for understanding their biology and ecology, and global preparedness for and progress toward their prevention, control, and mitigation. This report summarizes the presentations and discussions from the workshop.

Book Description
African horse sickness virus is a double-stranded RNA virus which causes a non-contagious, infectious arthropod-borne disease of equines and occasionally dogs. Nine distinct, internationally recognised serotypes of the virus have so far been identified. This book is based upon the findings of two programmes funded by the European Commission. It will be of value not only to the specialist research workers but also to veterinary workers dealing with control and to legislators seeking to promote safe international movement of equines. The topics covered include state-of-the-art discussions on diagnostics, vaccines, molecular biology, vector studies, and epidemiology.

Book Description
The Geographical Distribution of Animal Viral Diseases attempts to shed some light on the global distribution of 110 different viral diseases, mainly of livestock and companion animals. The world literature was screened for 110 different viruses, and maps were prepared. These maps delineate the global distribution of pathogenic viruses based on authenticated reports from a variety of reliable sources. Four viruses were categorized as affecting more than one species to a significant degree (astrovirus, rabies, rotaviruses, and Rift Valley fever). The largest number of maps involved viruses that affect humans. Of the 28 viruses a large number were from the California encephalitis group. Ten of the 28 viruses were reported only in the Eastern Hemisphere, 14 only in the Western Hemisphere, and four were worldwide. Birds were the next most frequently affected group with the 15 viruses, followed by pigs with 14 viruses. Overall the vector-borne viruses appear to have much sharper and clear-cut geographical boundaries than the others.

Book Description
Theileriosis is the name given to infections caused by several species of Theileria, the most important of which in Africa are Theileria annulata and Theileria parva. Their distributions in the continent are distinct, and follow that of their main field tick vectors. The annulata occurs in North Africa and the Nile River Valley, and the parva in sub-Saharan eastern, central, and southern Africa. This book reviews the work on theileriosis since 1902 from an historical, biological, ecological, epidemiological, and economic point of view. The results shed new light on poorly understood areas in theileriosis and at the same time assist with the development of more robust control strategies. Focuses on a tick borne parasite that threatens twenty-five million cattle in Central and East Africa Assembles all current data on the epidemiology of theileriosis in Africa Lays the groundwork for future studies

Book Description
Most of the future increase in livestock production is expected to occur in the tropical and subtropical regions of the world. Cattle are the most numerous of the ruminant species in the tropics and provide the largest quantity of animal food products. More than one-third of the world's cattle are found in the tropics. Disease is the major factor which prohibits full utilization of these regions for cattle production. Various infectious and transmissible viral, rick ettsial, bacterial, and particularly protozoan and helminthic diseases, are widespread in the tropics and exert a heavy toll on the existing cattle industry there. This uncontrolled disease situation also discourages investment in cattle industries by private and government sectors. In Africa alone, it is estimated that 125 million head of cattle could be accommodated in the tropical rainbelt if the disease and other animal husbandry factors could be resolved. The potential of efficient cattle production under more favorable conditions prompted various international agencies to establish a multi million dollar International Laboratory for Research in Animal Diseases (ILRAD) in Nairobi, Kenya, Africa. In South America, principal sites for raising cattle are shifting to the savannah lands because the more fertile soils are being used for crop produc tion, however, in the savannahs also, disease remains the most powerful deterrent in implementing the cattle industry.
