嫩江流域齐齐哈尔段犬、猫华支睾吸虫感染情况调查

Investigation on Clonorchis sinensis infection in dogs and cats in Nenjiang River basin Qiqihaer City

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 investigate Clonorchis sinensis infection of the reservoir host（cats and dogs） in Nenjiang River basin Qiaihaer City so as to provide the reference for the prevention and control of clonorchiasis.Method The feces of reservoir hosts from the villages and river banks was collected,and the livers and gallbladders of dogs were also collected from the animal slaughterhouses in surrounding counties and cities.The Clonorchis sinensis eggs in the feces of the reservoir hosts were detected with modified Kato method; the infections of adult Clonorchis sinensis in the livers and gall bladders of dogs were checked up with anatomical method.Result The total infection rate of the eggs of Clonorchis sinensis in the reservoir hosts was 8.00%（4/50）,with 8.57%（3/35） in the dogs and 6.67% （1/15） in the cats from Nenjiang river around Qiqihaer City.The infection rate of the adult Clonorchis sinensis in dogs was 5.71%（2/35）.Conclusion The Qiqihaer region of Nengjiang fiver basin is epidemic region of clonorchiasis,and the comprehensive measures including survey,treatment and health education etc.for preventing and controlling clonorchiasis should be strengthened to reduce the harm of clonorchiasis to the people＆#39;s health in the region.
