Abstract

During 2006–2008, twenty cases with sparganosis caused by eating live tadpoles emerged in Henan province, central China. To determine seroprevalence of anti-sparganum antibodies and obtain information about habits of eating live tadpoles and risks for sparganum infection, a serological survey was carried out in one village of Henan. Antisparganum IgG in 298 serum samples were assayed by ELISA using excretory and secretory (ES) antigens of Spirometra mansoni spargana. The results showed 56.71 % (169/298) of inhabitants had the history of eating live tadpoles. The overall seroprevalence was 5.7 % (17/298). The seroprevalence of the inhabitants who had the habit of eating tadpoles (9.47 %) was obviously higher than those who did not (0.78 %) (P < 0.01). Eating live tadpoles had become the most common risk behavior for sparganum infection. Hence, the comprehensive public health education should be carried out in endemic areas, and the habit of eating live tadpoles must be discouraged.
