猪衣原体病的调查

Investigations on Chlamydiosis in Pigs

1 98 6-2 0 0 2年从全国 1 7个省部分猪场收集猪血清 1 7448份 ,用间接血凝试验 ( IHA)检测猪衣原体抗体 ,其中青海猪衣原体抗体阳性检出率为 3 3 .3 %和 42 .9% ,四川 1 1 .5%和80 .0 % ,新疆 2 2 .2 % ,陕西 3 8.0 % ,广西 2 1 .2 % ,云南 2 4.5% ,广东 50 .2 % ,甘肃 42 .2 %和3 6.0 % ,河南 3 5.1 %和 1 8.2 % ,宁夏 1 5.1 % ,海南 3 8.2 % ,湖北 3 7.5% ,湖南 1 6.7% ,江西 50 .0 % ,辽宁 43 .2 % ,黑龙江 77.1 % ,吉林 2 0 .5%。并从一些省区所采的流产胎儿、流产母猪阴道拭子、仔猪肺炎死亡病例病料分离到鹦鹉热衣原体。从东北三省猪群检出衣原体抗体在国内属首次报道。

17 448 serum samples from pigs of various swineries in the seventeen provinces were examined for antibodies against chlamydiosis by an indirect hemagglutination (IHA) test,of which the detectable rates of positive for antibodies to chlamydiosis were 33.3% and 42.9% in Qinghai,11.5% and 80.0% in Sichuan, 22.2% in Xinjiang, 38.0% in Shaanxi,21.2% in Guangxi,24.5% in Yunnan, 50.2% in Guangdong, 42.2% and 36% in Gansu,35.1% and 18.2% in Henan,15.1% in Ningxia, 38.2% in Hainan,37.5% in Hubei, 16.7% in Hunan, 50.0% in Jiangxi,43.2% in Liaoning, 77.1% in Heilongjiang and 20.5% in Jilin. And organisms that were identified as Chlamydia psittaci subsequently had been isolated from the specimens collected from aborted fetuses and piglets with pneumonia. The report on the detectable rates of positive for antibodies to chlamydiosis in the Northeastern region of China is the first paper.
