First with the adult testis sinensis adult antigen (protein content of 75 to 150 micrograms per milliliter) to the county secondary and primary school students for skin test, followed by 1423 skin test-positive were fecal (direct smear method) and found Echinoderms eggs 29, the infection rate of 2.1%; primary infection rate of 2.1% (21/998), 1.9% of middle school students (8/425). At the same time check the other intestinal worms, roundworm, hookworm, whipworm infection rates were 64.6%, 6.9%, 4.07%. In 29 cases of C. sinensis infection, the minimum number of gram-positive fecal eggs was 100 and the maximum number of eggs was 6800. Two cases were moderately infected while others were mild infections. All infected persons generally no obvious symptoms.
