[Study of taeniarhynchosis in 5 districts of the People's Republic of Bulgaria with reference to chemoprophylaxis. Report given during the IVth symposium of the GDR on "Taeniarhynchosis-Cysticercosis" on April 26th, 1974 in Schwerin].

1968-1972 in five districts of DR Bulgaria 666 persons with Taeniarhynchus saginatus infection were registered, 64% of these tapeworm carriers lived in the country, 36% were townspeople. The incidence of infection in women was twice as high as in man. There were differences in incidence in jobs, 21.6% in farm workers, 20.2% in industrial workers, 13.8% in workers in the tobacco industry, 14.2% in housewives, 12.1% in pulls, 9.2% in office workers and 8.1% in pensioners carried tapeworms. Only 1.4% of animal breeders were infected with T. saginatus. The incidence of infestation increased in relation to the age. - In the Kardschali district, the tobacco farmers with a disease incidence of 34.8% represented a large part of the total incidence in the country. The private keeping of animals is still widespread in the country. The disease incidence increases between the age groups 20-40 years. The reason for the above is people eating increased uncontrolled animals. Individual food preparation habits and ignorance of the source of meat also account for spread of infection of people. As a trial three prophylactic methods were tested to establish a reduction of this disease.
