tablished only by the isolation of eggs and the species was not determined. Among the infected people 27 were men. Three of these were butchers and one a worker in a slaughter-house; the professions of the others were indifferent as to the source origin of infection. The 94 infected women were mostly houswives, three worked in catering trade and in the kitchens of children's institutions, and one case was detected in 1970 during our screening examinations at the Szerencs Chocolate Factory. That children are not indifferent to Taenia contamination either is shown by the 12 cases we encountered. Medical treatments were in most cases carried out by application of Atebrin and Pentilen through intraduodenal probe at the internal and infectious departments of the county hospitals but in some cases the district doctor attempted treatment of outpatients, although without success. Treatment with Yomesan was tried in 1966-67, but the favourable effect of the drug noted by LENGYEL et al.

(1968) was not found here and its efficacy was well below that of the other two drugs. It was established that 52 of the patients recovered after treatment, 20 persons showed no response, and in 61 cases the result is not known as no follow-up observations were made. During the 10-year period we maintained contact with 19 of the patients and were able to carry out control examinations on several occasions. A woman at Rudabánya and a boy at Sátoraljaújhely were positive at the beginning of the observation period and were still positive 10 years later. The woman was treated for the first time at home, in 1965, with Pentilen, by her district doctor, then in 1967, and again at the end of 1970, with Atebrin, at the infectious department of the county hospital. During the most recent treatment 1971 we have found no scolices at the control examination. The boy was also treated three times during the 10 year period.
