摘要
目的观察长江河口段苏南江滩水土对钉螺生存繁殖影响。方法检测长江河口段水质及江滩土质并进行实验室和室外饲养钉螺,观察其生存、繁殖及感染情况。结果对照组水质主要指标值在实验组各点之间;土质所有指标值在实验组各点之间。实验组和对照组6个月和12个月后的钉螺存活率差异均无统计学意义;螺卵平均孵化率83.60%,各组间差异无统计学意义;子代成螺经人工感染60d后,感染率为1.40%。结论钉螺在长江河口段实验室和室外能够正常生存和繁殖,其子代钉螺能够在实验室感染血吸虫。
Objective To observe the oncomelania survival reproduction rate and susceptibility to water and soil in the Yangtze River estuary of Sonam. Methods The soil and water from the Yangtze River estuary of Sonam were used for the experiment,and were used to rear oncomelania in the laboratory and exterior. The oncomelania survival reproduction rate and infection of schistosomiasis were ob- served. Results There was no significant difference between experimental and control groups for the oncomelania survival rate in both 6 and 12 months groups. The average hatchability rate of oncomelauia egg was 83.60%,average in each group no significant difference between. The infection rate of the second generation oncomelania of the schistosomiasis was 1.40% after 60 days infection in the laboratory. Conclusion The oncomelania can be able to survival reproduction in the Yangtze River estuary in Sonam laboratory and exte- rior. The second generation of the oncomelania can be infected by schistosomiasis in the laboratory.
