The problem of echinococcosis in Bułgaria is discussed in the light of world literature. The percentages of dogs infested with Echinococci are: 16% in towns, and 40% in the country. The invasion happens frequently also in slaughter animals and was found in 66.5% of sheep, 40.8% of cattle and 4.42% of swine. Infections of man are not rare. In the years 1901-1959 a total of 5617 cases was recorded, what means 350 cases yearly on the average. This concerns particularly rural popu1ation, whereby women more frequently become infected than men. The author also discusses the localization of the parasite in varfous organs of man, the more unique and interesting clinical cases, the mortality and other epiemiological data. This is a summing up of a number of papers and publications which on this subject appeared in the Bulgarian literature.
