摘　　要：目的了解金华市野生淡水鱼虾华支睾吸虫囊蚴感染情况。方法按金华市主要水系分布特点采集3个县的河道、水库、池塘随机捕获的野生淡水鱼虾,用直接压片镜检法检测野生淡水鱼虾肌肉中华支睾吸虫囊蚴。结果在18种野生淡水鱼虾中检出华支睾吸虫囊蚴的有11种,占61.11%;检测鱼虾2 326尾,其中阳性131尾,总感染率为5.63%。鱼类感染率为8.24%,高于虾类感染率2.96%(P<0.01)。不同调查县感染率不尽相同(P<0.01),其中以处于水系下游的婺城区水域鱼虾感染率最高为12.92%。不同水域环境感染率差异有统计学意义(P<0.01),以池塘感染率为高10.18%。不同种类野生淡水鱼的感染率差异有统计学意义(P=0.00),以旁皮鱼(17.65%)和麦穗鱼(17.65%)为最高。结论金华市野生淡水鱼虾有不同程度的华支睾吸虫囊蚴感染,生食或半生食淡水鱼虾,存在感染华支睾吸虫病的风险。Objective To learn the status of wild freshwater fish and shrimp infected with metacercaria of clonorchis sinensis in Jinhua city.Methods Wild freshwater fish and shrimp were randomly captured in river channel,reservoir and pond from 3 counties according to the distribution characteristics of main river system in Jinhua city.Direct tabletting microscopic examination was used to detect metacercaria of clonorchis sinensis in the muscle of wild freshwater fish and shrimp.Results A total of 1 1 kinds of wild freshwater fish and shrimp were infected with metacercariae,accounting for 61 .1 1 %（1 1 /1 8）,and the total infection rate was 5.63% among 2 326 wild freshwater fish and shrimp.The infection rate of fish（8.24%）was significantly higher than that of the shrimp（2.96%）（P 〈0.01 ）.There were significant differences in the infection rate among different counties （P 〈0.01 ）,and the infection rate in the downstream of the water system in Wu water area （1 2.90%）was the highest.Also,significant differences were observed in infection rate among different water environments （P 〈0.01 ）,and the infection rate of pond （1 0.1 8%）was the highest.Significant differences were observed in the infection rate among different kinds of wild freshwater fish （P =0.00）,and the infection rate of side skin fish（1 7.65%）and psendorasbora parve（1 7.65%）were the highest.Conclusion There were metacercaria of clonorchis sinensis infection in wild freshwater fish and shrimp with different degrees in Jinhua city.People who ate raw or undercooked freshwater fish and shrimp may be at the risk of infection.
