【摘要】：目的了解福建省动物宿主感染巴贝虫状况。方法 2014-2016年本中心在福建各地捕鼠,笼日法捕鼠,采集鼠心脏血,同时采集牛、羊和狗的血液样本,采用PCR扩增巴贝虫18SrRNA基因,感染率的比较采用χ2检验或Fisher’s确切概率法。结果调查共布放鼠笼5 917笼次,捕鼠381只,鼠密度为6.44%。全省鼠类巴贝虫的感染率7.61%。家栖鼠中仅3只感染巴贝虫,感染率为1.68%。野鼠中26只感染巴贝虫,感染率为12.87%。野鼠感染率远高于家鼠,差异存在统计学意义(P0.05)。地区分布看,闽中地区感染率最高,其次为闽东,闽南地区感染率最低,差异存在统计学意义(P0.05)。其他动物,牛的血样未检出巴贝虫,狗和羊的血样中各1只检出巴贝虫,感染率分别为1.79%和0.55%。鼠类的巴贝虫感染率高于其他动物的感染率,差异存在统计学意义(P0.05)。序列分析显示鼠类感染的均为田鼠巴贝虫。而犬中检出的巴贝虫为犬巴贝虫。结论福建省巴贝虫宿主动物中鼠类尤其是野鼠,感染率最高,可能是我省巴贝虫最重要的宿主。
[Abstract]:Objective to understand the situation of animal host infection with Babel worm in Fujian Province. Methods from 2014 to 2016, the center caught mice in Fujian, caught mice in cage, collected blood from heart and collected cattle at the same time. The 18s rRNA gene was amplified by PCR from the blood samples of sheep and dog. The infection rate was compared by 蠂 2 test or Fisher's exact probability method. The density of rats was 6.44. The infection rate of Babel species in rats was 7.61.Only 3 of the house rodents were infected with Babel, the infection rate was 1.68. 26 of the wild rats were infected with Babel. The infection rate of wild rats was much higher than that of domestic rats, and the difference was statistically significant (P 0.05). In the regional distribution, the infection rate in central Fujian was the highest, followed by the east of Fujian. The infection rate was the lowest in the south of Fujian, and the difference was statistically significant (P 0.05). No Babel worm was detected in the blood samples of other animals and cattle, and 1 was detected in the blood samples of dogs and sheep. The infection rates were 1.79% and 0.55, respectively. The infection rate of Babel worm in mice was higher than that in other animals. The difference was statistically significant (P0.05). The results of sequence analysis showed that all of the infected mice were Barb 茅 worms of voles and those of dogs were Babel canis. Conclusion the rats, especially wild mice, are host animals of Babel species in Fujian Province. The infection rate is the highest and may be the most important host of Babel worm in our province.
