目的了解江苏省邳州市和新沂市华支睾吸虫在淡水鱼中的流行状况,为下一步的防治提供科学依据。方法在邳州市和新沂市自然水域中抓取野生麦穗鱼和棒花鱼,用压片镜检法检测鱼体内的华支睾吸虫囊蚴,分析感染数据。结果共解剖麦穗鱼和棒花鱼1 117条,其中麦穗鱼792条(占70.90%),棒花鱼325条(占29.10%)。麦穗鱼和棒花鱼华支睾吸虫囊蚴总感染率分别为29.80%(236/792)和4.62%(15/325),差异有统计学意义(χ~2=83.88,P<0.01)。结论新沂市和邳州市淡水鱼华支睾吸虫囊蚴感染率较高,当地居民面临着较高的感染华支睾吸虫的风险。
Objective To understand the prevalence of Clonorchis sinensis in freshwater fish in Pizhou and Xinyi of Jiangsu Province and provide a scientific basis for further prevention and treatment. Methods Wild wheat and barramundi were caught in the natural waters of Pizhou and Xinyi. The infection of cercariae of Clonorchis sinensis in the fish was detected by the microscopy. Results A total of 1 117 wheat and barramundi were dissected, of which 792 were wheat spikes (70.90%) and 325 were saliva (29.10%). The total infection rates of metacercariae of C. sinensis and C. monocytogenes were 29.80% (236/792) and 4.62% (15/325), respectively, with significant difference (χ ~ 2 = 83.88, P <0.01) . Conclusion The infection rates of Clonorchis sinensis metacercaria in Xinyi and Pizhou freshwater fish are high, and local residents are at high risk of Clonorchis sinensis infection.
