新疆高寒地区家畜、家禽胆汁与肠内容物中的弯曲菌带菌情况的调查分析

The survey and analysis on campylobacter carrier rate of the bile and intestinal contents of the livestocks,poultries in alpine area of Xinjiang

目的调查高寒地区家畜、家禽胆汁与肠内容物中弯曲菌的分布情况。方法对12种家畜、家禽胆汁与肠内容物中的弯曲菌进行分离、培养、鉴定,并观察7种家畜、家禽胆汁弯曲菌的存活时间。结果在1814份家畜、家禽胆汁中发现,猪、牛、马、羊、狗、猫、鸡、鹅、鸭、鹌鹑、鸽子、家兔的胆汁中弯曲菌带菌率分别为6.67%、4.17%、4.94%、3.64%、8.93%、19.05%、6.41%、2.78%、6.48%、24.39%、5.66%、0。体外实验证明,弯曲菌在胆汁中可存活4～7周。结论高寒地区家畜、家禽肠内容物的带菌率均高于同种家畜、家禽的胆汁带菌率,提示该区家畜、家禽是弯曲菌的重要传染源。

Objective To investigate the distribution on campylobacter of the bile and intestinal contents of the live-stock, poultries in alpine area of Xinjiang. Methods To isolate, culture, and identify the campylobacter of the bile and intesti- nal contents in 12 kinds of livestock and poultries and observe the survival time of campylobacter in 7 kinds of livestock and poultries. Results The Campylobacter carrier rate of the bile was 6.67% , 4.17% , 4.94% , 3.64% , 8.93%, 19.05% , 6. 41% ,2.78% ,6.48% ,24.39% ,5.66% and 0. 0% in the pigs, cows, horses, sheep, dogs, cats, chichens, gooses, ducks, quails and pigeons and rabbits respectively. The survival time of campylobacter in the bile in vitro was 4 to 7 weeks. Conclu- sion The Campylobacter carrier rate of the intestinal content was higher than that of the bile about livestock and poultries in alpine area of Xinjiang. It is believed that the domestic animals and fowls may be an important source of campylobacter infec- tion in human beings according to our findings.
