During the last few years the echinococus disease appears as a big social and economical problem. Mainly stray dogs propagate the disease. From 1968 to 1986 the total number of registered in Bulgaria was between 60 000 to 100 000. Only 20-30% (12 000- 20 000) of them were abandoned. In 1992 after the examination in slaughterhouses, parasites in 26-40% of the sheep were founded, 0.95-1.15% in pigs and 0.75-2% in cattle. During the studied period these percentage is higher and in some sheep 90% of them were affected by parasites (echinococus cysts). The localization of the parasites was mainly established in the liver (52-53%) in the sheep and pigs 28-30% - in the lungs and in 17-20% of the cases in both organs, in cattle lung is more affected - 58%. It was concluded that the dogs were the main cause in the epizootology of the echinococcosis.
