目的了解嫩江流域齐齐哈尔段保虫宿主犬和猫的华支睾吸虫感染情况,为华支睾吸虫病的防治提供参考依据。方法从嫩江流域齐齐哈尔段周边村庄及河岸边采集犬和猫的粪便,在周边县市的动物屠宰场收集犬的肝脏及胆囊:采用改良加藤法检查犬和猫粪便中华支睾吸虫虫卵的感染情况;采用解剖法检查犬的肝脏及胆囊内华支睾吸虫成虫的感染情况。结果嫩江流域齐齐哈尔段华支睾吸虫保虫宿主粪便虫卵的总感染率为8.00%(4/50),其中犬粪虫卵感染率为8.57%(3/35),猫粪虫卵感染率为6.67%(1/15);解剖法发现华支睾吸虫保虫宿主犬的成虫感染率为5.71%(2/35)。结论嫩江流域齐齐哈尔段为肝吸虫病流行较为严重地区,建议加大查治和健康教育等多种防控措施力度,减少华支睾吸虫病对嫩江流域人民的健康危害。
Objective To understand the infection of Clonorchis sinensis in host dogs and cats in the Qiqihar section of Nenjiang River basin and provide a reference for the prevention and treatment of Clonorchis sinensis. Methods The dogs ’and cat’s feces were collected from the villages and riverbanks in the vicinity of the Qiqihar section of Nenjiang River basin. The dogs’ liver and gallbladder were collected from the animal slaughterhouses in the surrounding counties and cities. The infection of Clonorchis sinensis eggs in dogs and cats The anatomical method was used to examine the infection of adult dogs with Clonorchis sinensis and canine liver. Results The total infection rate of stool egg of the hosts was 8.00% (4/50) in Clonorchis sinensis in Qiqihar of Nenjiang River drainage area. The infection rate of canine egg was 8.57% (3/35) Was 6.67% (1/15). The adult infection rate of Clonorchis sinensis host was 5.71% (2/35). Conclusion The Qiqihar section of Nenjiang River Basin is a serious area where the prevalence of clonorchiasis is very high. It is suggested that more efforts should be made to prevent and control Clostridium sinensis to the health of people in Nenjiang River basin.
