With regard to the clinical symptoms

,it has been our experience that patients attend the doctor only after discharge of the proglottides of after the strobila have broken down. Screening examinations revealed 7 taeniosis cases. In most cases general symptoms predominated although requent giddiness and retching were common. Phychic injuries are not uncommon in chronic cases, particularly in conduction with neurotic complaints that disappear after the worms have been elimated. The slight incidence of T. solium compared with T. saginata is striking but matches the figures for country and for Europe as a whole. KOTLÁN" has explained this phenomena as due to the different biological features of the two tapeworms and the two intermediate hosts. Pigs - being coprophages - swallow large numbers of Taenia eggs so that cysticerci can develop in their muscles quite considerable quantities. This makes diagnosis in slaughter-houses easier. Since the end of the 2nd World War the age of pigs at slaughter has become lower and has thus contributed to the decrease in swine cysticercosis cases. According to JEPSEN and ROTH'

s (19) Investigations in Denmark in 1949,cattle are usually only weakly infected, since Taenia eggs seldom get into the feeding-straw and pastures. In County Borsod - especially In Bodrogköz - stables and barns are often contaminated with Taenia eggs because of the lack of latrines and also the rare use of the existing ones. In the course of slaughter-house inspections several cases of Cysticercus bovis have been diagnosed have been in Bodrogköz during the last 2-3 years. A few screening examinations have been made in the direct surroundings of the cattle owners with negative results. The experiences we have gained in the course of this work show that the tasks we face in Hungary for eradicating human taeniosis are as follows: 1. Proper enforcement of Ministry of Health order No. 19/1966 to ensure earlier notification of cases.
