本文报告卫氏并殖吸虫囊蚴经腹腔及经口实验感染家犬的结果。感染后75～104天剖检,从肺脏虫囊中检获成熟虫体。12头家犬共检获虫体915条。虫在肺内的分布,右肺明显多于左肺。腹腔注射法及胃管喂饲法的虫体回收率分别为38.11%及38.16%,两者无明显差异。在感染家犬的操作方法上,腹腔注射法优于胃管喂饲法。本实验可为临床X线诊断及人工感染家犬后收集成虫作参考。
This article reports the results of intra-peritoneal and oral tests on the domestic dog of Paragonimus westermani. Post-infection necropsy 75 to 104 days later, mature worms were recovered from the lung worm sac. A total of 915 worms were detected in 12 dogs. The distribution of insects in the lungs was significantly greater in the right lung than in the left lung. The recovery rates of the parasites were 38.11% and 38.16% for the intraperitoneal injection and the gastric tube feeding, respectively. There was no significant difference between the two groups. In the method of infection of domestic dogs, intraperitoneal injection is superior to gastric tube feeding. This experiment can be used as a reference for clinical X-ray diagnosis and artificial infection of domestic dogs.
