A review is made of the health fields where collaboration between veterinarians and physicians and with other professions is most needed. The main obstacles encountered in this collaboration are recognized in institutional and attitudinal factors such as the type of administration in which veterinary services are located, economic interests, isolated spheres of activity of both veterinarians and physicians, reactions of the public to Veterinary Public Health action, insufficient fund allocation, etc. Control of echinococcosis/hydatidosis and brucellosis is given as an example of fruitful intersectoral collaboration supported by health institutions at local and international levels. It is stressed that the need for intersectoral collaboration is being increasingly and universally accepted with the active involvement of concerned organizations at all levels.
