13 Brucellosis situation in Mongolia o Though many infectious diseases are controlled, the cases of brucellosis communicable to humans are increasing, and according to the record of health organization, brucellosis among human infectious diseases ranks after infectious hepatitis.

14 o Until 1990 livestock had been in public ownership and belonged to agricultural farms and state cooperatives. Therefore, losses and diseases of livestock were centrally controlled, and preventive and fighting measures were implemented on the national level including individually owned livestock and animals. o After 1990 ninety five present of livestock were transformed into private ownership, consequently began to be provided paid veterinary services, and furthermore, the financial possibility to render support by the state became limited. These are the main reasons of the increase of brucellosis cases among livestock and the population.

15 Brucella melitensis - in sheep and goats Brucella abortus in cattle Camels and yaks can be infected by both Both species pathogenic for man

16 Alive vaccines Rev1 Br.melitensis for small animals Strain 19 Brucella abortus for cattle Use for long period of time

17 Brucellosis diagnosis Rose Bengal test CFT ELISA PCR Diffrenciation vaccinated and natural infected animals Targeted surveillance

28 Comments and question Thank you

29 o The new document regulates relationship between herders whose interests and needs are to keep the livestock healthy, on one hand, and on the other hand, veterinarian s interest to provide veterinary services. However, without sound financial support from the government side it is not possible to implement the policy. o Cost effective methods based on realistic assessment of the present situation should be used to implement the brucellosis eradication and control program in Mongolia.

30 o One has to realize that there are socio-economic factors negatively influencing the fight against brucellosis. In addition, there are biological factors with negative influences.
