[Incidence of echinococcosis in animals]

Studies were carried out on echinococcosis in animals, making use of the results obtained with investigations carried out throughout this country. A great number of definitive and intermediate hosts were studied. A considerable drop of the percent of infected animals was recorded over the 1966-1984 period both with the definitive and the intermediate hosts. Data is presented on the territorial spread of hydatid echinococcosis. Enumerated are the factors that bear an influence on this process. The demonstration of the high incidence of the disease as well as of the rising number of dogs substantiates the view that the epizootic status is still unfavourable, which is also due to some other factors.
