[Study on number and mature rate of eggs in gravid proglottids of Taenia solium].
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.


CONCLUSIONS
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%.
