An assessment of the strengths and weaknesses of current veterinary systems in the developing world Summary The changes that veterinary services have undergone in the developing world over the last two decades are expected to continue and result in the further privatisation of selected tasks, the decentralisation of decision-making and a move towards more focus on public goods service delivery by State veterinary units. At the same time, global food consumption patterns are changing in numerous ways, which will certainly affect veterinary services delivery systems. These changes include a trend towards increasing globalisation, rapidly escalating consumer demand for animal protein, intensification of livestock production into larger units and growth of the trade of livestock and livestock products. Intensification of livestock production into larger units and global trade will increase the challenges resulting from the resurgence of serious animal diseases, food safety hazards and veterinary public health-related problems. Facing and managing these challenges raises issues related to animal health delivery systems and national policies that will have to be addressed. Strengthening the capacity of State veterinary units to respond to regulatory responsibilities dictated by national laws and international World Trade Organization and OIE (World organisation for animal health) health standards will be at the centre of animal health policies in most developing countries. Creating an environment which facilitates privatised service delivery and supports subcontracting is likely to contribute to improving economic efficiency and providing wider access to veterinary services. Equally important is the issue of professional development, which must be addressed by refocusing veterinary curricula and improving professional standards. The profession will then be in a better position to serve the needs of increasing numbers of consumers.
Brucellosis causes substantial economic losses in sheep and goat flocks, in addition to causing a debilitating disease, called Malta fever, when transmitted to humans. In many countries, the control of brucellosis in small ruminants is principally based on the use of the live Brucella melitensis Rev. 1 vaccine (10). This vaccine considerably increases the resistance of animals to infection and reduces the number of Brucella-induced abortions (2, 5, 19). However, when this
