    Guidelines for coordinated human and animal brucellosis surveillance 2003
    Also available in:

    Brucellosis remains a major source of disease in domesticated animals, wildlife and humans. Although reported incidence and prevalence of the disease vary widely from country to country, bovine brucellosis caused mainly by Brucella. abortus is still the most widespread form. In sheep, goats and humans, brucellosis caused by Brucella melitensis is by far the most important clinically apparent disease. Brucellosis is still a major disease problem in the Mediterranean region, western Asia, parts of Africa and Latin America. The zoonotic significance of Brucellosis requires concerted efforts at control through intersectoral collaboration between the Ministiries of Agriculture and Health. Such collaboration will depend to a large extent on the availabilty of science based information collected through efficient surveillance systems for the purpose of designing practical and feasible control strategies to reduce prevalence of the disease and where feasible, eradicate it. These guidelines ha ve been prepared with that aim. They have been developed by reviewing programmes in countries that have successfully controlled and eradicated Brucellosis as well as those countries in which the disease is still endemic. In using these giudelines for human and animal brucellosis surveillance it must be emphasised, that what has been successful in one country may not necessarily be successful in another based on factors such as level of control of animal movement and socio-cultural practices and habits. It is therefore suggested that these guidlines be modified to suit prevailing local conditions and animal management systems.

    A basic laboratory manual for the small-scale production and testing of I-2 Newcastle disease vaccine 2002

    Chickens are susceptible to many infectious diseases. One of the most important of these is the viral disease known as Newcastle disease, which causes devastating losses in both commercial and village chickens. Newcastle disease can be controlled by the use of vaccines. However, many Newcastle disease vaccines deteriorate after storage for one or two hours at room temperature, making them unsuitable for use in villages where the vaccine may need to be transported for hours or in some cases days at ambient temperature. The I-2 Newcastle disease vaccine is more robust and therefore does not deteriorate as quickly as traditional vaccines. This manual summarizes the basic laboratory procedures used to produce and test experimental I-2 thermostable Newcastle disease vaccine in the research and training programmes associated with the John Francis Virology Laboratory.

    Strategies for sustainable animal agriculture in developing countries 1993

    he FAO Expert Consultation on Strategies for Sustainable Animal Agriculture in Developing Countries was held at the FAO Headquarters in Rome, Italy, from 10 to 14 December 1990.Animal agriculture is a complex, multi-component, interactive process that is dependant on land, human resources and capital investment. Throughout the developing world it is practised in many different forms, in different environments and with differing degrees of intensity and biological efficiency. As a result any meaningful discussion of the subject must draw on a broad spectrum of the biological and earth sciences as well as the social, economic and political dimensions that bear so heavily on the advancement of animal agriculture. There is a growing consensus among politicians, planners and scientists alike that livestock production in the third world is not developing as it should, or at a sufficient pace to meet the high quality protein needs of a rapidly expanding human population. The sobering reality is, despite the many development projects implemented over the years by national, bilateral and multinational agencies and often substantial capital investment, there has been little or no change in the efficiency of animal production in the developing world. Livestock numbers have increased substantially in many countries and while the growth in output is welcome, it does not necessarily equate with sustainable productive growth. On the contrary it can, as it has done in the drought prone arid regions, lead to a lowering of productivity and degradation of the rangelands.The purpose of the Expert Consultation was to discuss and formulate specific criteria and questions relating to the planning and implementation of sustainable livestock production programmes in the developing world. There is increasing concern regarding the conservation of the natural resource base and protection of the global environment and FAO attaches highest priority to the sustainable development of plant and animal agriculture. This Expert Consultation is one of a number of initiatives being undertaken by FAO to ensure the sustainability of it's agricultural development programme. The discussion and recommendations arising from this Expert Consultation have been used to help to focus and guide global, regional and national policies and action programmes on the sustainable development of agriculture and have provided an important contribution to the FAO/Government of the Netherlands International Conference on Agriculture and the Environment held in the hague, 15–19 April, 1991.
