[Current situation of the most frequent zoonosis in the world].
Zoonoses are at the present time more important than ever due to their magnitude and impact. The international trade in animals, products and sub products, as well as the intense travel of people around the world, represent risks of dissemination of infectious diseases, and are the reason for a new age of emerging and reemerging zoonotic diseases. Under these conditions, public health and animal health authorities are obliged to work together in order to get more efficient control programs. In this paper the actual situation of some important emerging and reemerging zoonoses is analyzed, including: anthrax, rabies, tuberculosis, brucellosis, cysticercosis, echinococcosis, hanta virus, Hendra and Nipah virus. Particular attention is given to leptospirosis, due to the fact that it is considered by WHO and OIE as the widest spread zoonotic disease in the world. Zoonoses caused by ingestion of animal food products are discussed. They are responsible for the death of almost 2.2 million people. Bacteria of genus salmonella and campylobacter are considered. Some recommendations are given for the control and prevention of zoonoses, emphasizing the "One Health" concept.
