Abstract: 【Abstract】  The current status and species of Taenia sp. were investigated in Midu County by sedimentation method to examine eggs of Taenia sp. in stool, questionnairing as well as deworming by areca-pumpkin seeds in October-December, 2010.  The infection rate of Taenia sp. was 15.7%（65/414）. Among the positives, it was fairly high in the age groups of 40- and 50-, being 24%(21/85)and 26%(15/57), respectively. 26 cases with positive stool examination and 47 cases with a history of discharging proglottids were treated. Adult worms were collected from all 26 egg positive cases and 23 persons discharging proglottids. The highest number of adult worms expelled was 11 in a woman, 2 worms from another villager, but only one worm each from all other cases. 15 tapeworms with scolex and mature proglottids were examined and morphologically identified as T. asiatia. The high prevalence was related to the residents′ dietetic habits (eg. eating raw pork and liver), behaviour (eg. defecating in field), and the egg-contaminated environment (eg. by untreated feces).
