1989年4月,在和硕县选8个点进行现场调查,对310条犬进行了槟榔碱测试,以评价该县包虫病防治的近期效果。结果表明,该县犬群的登记管理比例由1988年的95％降至1989年的61.98％。1988、1989两年驱虫强度的各项指标分别为:平均驱虫次数2.85和0.85次;平均驱虫密度为35.63％和28.6％;驱虫效率为0.99和0.64。这种驱虫强度在16个月间使全县犬群Eg感染率由30％降至10.4％,但仍维持在全疆农区较高水平。驱虫1～2次的犬与未驱虫犬对Eg感染无显著性差异,阳性犬所占比例随驱虫次数增加而减小。驱虫频率在50天间隔内,犬阳性率可为零。未驱虫犬的相对感染风险是驱虫犬的2.53倍。犬主的民族、职业和犬的用途在犬的Eg感染中有显著差异。 本研究有力地支持了犬6周驱虫的防治对策,证实强化驱虫完全可以抵消社会因素和犬主行为对犬感染的影响,并发现犬同时感染Eg和大绦虫的机会比单独感染Eg的机会高4.99倍。 对以阳性犬来衡量人、畜感染潜在风险的观点进行了讨论。
In April 1989, 8 sites in Heshuo County were selected for on-the-spot investigation and 310 canines were tested for arecoline to evaluate the immediate effect of hydatid disease prevention and control in this county. The results showed that the percentage of dog populations in the county was reduced from 95% in 1988 to 61.98% in 1989. The repellent intensities in 1988 and 1988 were respectively 2.85 and 0.85 for average number of deworming. The average deworming densities were 35.63% and 28.6%. The deworming efficiency was 0.99 and 0.64 respectively. This deworming intensity reduced the Eg infection rate of the canine population in the county from 30% to 10.4% in 16 months, but still maintained a relatively high level in the rural areas of Xinjiang. There was no significant difference in Eg infection between 1 and 2 deworming dogs and non-deworming dogs. The positive proportion of positive dogs decreased with the increase of deworming times. Insect repellent frequency in the 50-day interval, the positive rate of dogs can be zero. The relative infection risk of un-wormed dogs is 2.53 times that of the worming dogs. Dog owners of ethnic, occupational and dog use have significant differences in canine Eg infection. This study strongly supports the prevention and treatment of 6-week repellent in dogs, confirmed that intensive deworming can completely offset the impact of social factors and dog behavior on dog infection and found that dogs infected with Eg and Taenia infection at the same time than Eg 4.99 times higher chances. The positive dog to measure the potential risk of human and animal infections were discussed.
