Abstract: 　Objective To investigate the number and mature rate of eggs in gravid proglottids of Taenia solium . Methods Ten worms of Taenia solium , expelled from patients, were detected. Eggs were collected from the last 10 gravid proglottids of each worm. Results & Conclusion The egg number in each mature proglottids varied from 3 900 to 126 520, and the mean number was 28 332. The mature rate of eggs was from 7.00% to 36.00% with an average of 29.12%, which was lower than that in proglottids naturally excreted with feces. With suitable temperature and humidity, the proglottids developed continually after excreted out of host body. Two to three days later, the mature rate of their eggs increased to 85%-90%.
