Abstract
The present study was undertaken to evaluate the prevalence rate of Taenia spp. infection and distribution of taeniasis caused by T. solium among Koreans in several localities in Korea during the period from 1977 to 1980. A total of 1,946 stool specimens collected from students and inhabitants of Chungcheong Bug Do and Gyeongsang Nam Do were examined by cellophane thick smear method. Among them, 40 persons were detected as Taenia egg positive cases. The overall positive rate of Taenia spp. shows 2.1 %. The prevalence rate of male (2.3 %) is relatively higher than that of female (1.4 %). In order to observe the distribution of Taenia solium infection, the whole worms or a part of proglottids of Taenia spp. were collected from the stools of egg positive cases by normal defecation or anthelmintic treatment. For the species identification, expelled proglottids were examined microscopically by the number of branches of the uterus, presence of a vaginal sphincter or the accessory ovarian lobe etc. Among 199 egg detected cases in this study 59 (39.1 %) out of 151 cases in Seoul, 12(40.0 %) of 30 cases in Gyeongsang Nam Do and 2 (25.0 %) from 8 taeniasis cases in Cheju Do were infected with T. solium. But none of T. solium infection was found from 10 egg positive cases in Chungcheong Bug Do. As a whole, the composition of species shows 36.7 per cent of T. solium infection and 55.8 % of T. saginata infection, and in 7.5 per cent the species were not identified.
