The recent introduction and spread of African swine fever (ASF) into Europe and Asia has shown that an integrated, multidisciplinary effort is needed to tackle this disease and the complex challenges it poses. This book presents practical guidelines on surveillance for detection of ASF virus, how to prevent outbreaks in the domestic pig sector through biosecurity and cleaning and disinfection routines, including in backyard holdings, and how to control and eradicate this disease in wild boar. Information on pathological lesions and diagnostic practices are provided to support practitioners.
African swine fever (ASF) is caused by a virus that is classified as a member of the Iridovirinae family. The disease in the warthog, the natural host, in Africa was described in 1921 by R. E. Montgomery. The reservoir of the vi rus is inti cks. The i ntroduct i on of domestic pi gs into territory occupied by warthogs i nf ected wi th ASF in the 1960's has endangered the pig industry around the world. The domestic pig is highly sensitive to ASF and develops a devastating disease that kills the pig without giving the immune system a chance to defend the animal against the virus infection. The ability of ASF virus to infect and destroy cells of the reticuloendothelial system leaves a defensele...
African swine fever (ASF) is endemic in some parts of eastern and southern Africa. The introduction of ASF into free areas leads to losses because of the devastating effects it causes. In order to minimize these losses, it is essential that there is a strong early warning and early reaction capacity. The key to such a system is disease recognition. The purpose of this manual is to enhance recognition of ASF at all levels for early warning and early reaction, so that the disease can be identified and eliminated at its earliest appearance in any area. Special attention has been given to the clinical, anatomical and pathological similarity of African swine fever with classical swine fever.

The purpose of document is to provide fact based overview of ASF ecology in the Northern and Eastern European populations of wild boar and briefly describe a range of practical management and biosecurity measures or interventions, which can help stockholders in the countries experiencing large scale epidemic of this exotic disease to address the problem in a more coherent, collaborative and comprehensive way. The handbook should not be viewed as an authoritative manual providing readymade solutions on how to eradicate ASF from wild boar. The facts, observations and approaches described in the document are presented with the intention to broadly inform veterinary authorities, wildlife conservation bodies, hunting community, farmers and general public about complexity of this novel disease and the need to wisely plan and carefully coordinate any efforts aiming at its prevention and control.
Given the current worsening of the African swine fever situation worldwide, this field manual will be aimed to assist veterinarians in the prompt recognition and detection of the disease and the immediate control steps at farm level.
Bluetongue may be described as an acute insect borne disease of ruminants, manifested clinically in sheep by a catarrhal inflammation of the mucous mem branes of the digestive and respiratory systems and associated with degenerative changes in the skeletal musculature. The profound emaciation and weakness which follow the acute disease are responsible for a protracted convalescence and for serious economic losses due to diminished productivity. II. Historical During the early colonisation of Africa, susceptible Merino and other European breeds of sheep were introduced into the Cape, at first by the Dutch East India Company between 1652 and 1785 and again later in 1870.

This specially curated collection features four reviews of current and key research on African swine fever (ASF). The global spread of ASF has been unprecedented. Since 2005 ASF has spread to over 60 countries across Asia, Africa and Europe. Since it first appeared in China in 2018, it has halved the commercial pig population in that country. Controlling ASP has proved challenging due to its complex epidemiology, difficulties in early detection and the current lack of an effective vaccine. This guide synthesises and reviews the research on key aspects of understanding, tracking and preventing this devastating disease. What is an Instant Insight? An Instant Insight gives you immediate access to key research on a topic, allowing you to get right to the heart of a subject in an instant and empowering you to contribute to sustainable agriculture.
This booklet provides guidance on prevention, detection and control of African swine fever (ASF) in resource-limited settings. It is designed primarily for places where ASF is endemic with few or no prospects of eliminating the disease, and places at high risk of incursion. The guide is divided into five sections. The first covers key aspects of the disease that can be exploited when developing prevention and control programmes, even when resources are limited. The next three sections provide suggestions on simple, low-cost measures for ASF prevention, early warning and detection, and control that have been shown to work in these settings. The last section considers ways that communities can...
