目的了解2012年新疆乌苏古尔图鼠疫自然疫源地动物间鼠疫流行动态。方法 2012年5月29日—9月10日依照《新疆维吾尔自治区鼠疫监测方案》及实施细则,以定点观察法监测长尾黄鼠密度,采用路线法调查灰旱獭密度,鼠疫四步检验法检验长尾黄鼠脏器、长尾黄鼠体蚤,采用间接血凝试验法检测长尾黄鼠血清和牧犬血清鼠疫F1抗体。结果长尾黄鼠6—7月密度分别为10.25只/hm2和17.43只/hm2,染蚤率88.9%,平均蚤指数6.3;灰旱獭6—7月密度分别为0.23只/hm2和0.38只/hm2;鼠疫病原学监测从长尾黄鼠及其体蚤分离出鼠疫菌11株,血清学检验长尾黄鼠血清354份,鼠疫F1抗体阳性12份,检测牧犬血清17份,阳性1份。结论 2012年古尔图鼠疫自然疫源地动物间鼠疫疫情活跃,存在波及人间的危险性,需继续开展有效的鼠疫监测工作。
Objective To understand the epidemiology of plague in the natural foci of the Usu-Gurzu Plague in Xinjiang in 2012. Methods From May 29 to September 10, 2012, according to the “Plague Surveillance Program in Xinjiang Uygur Autonomous Region” and its implementing rules, the density of Salmoides longus was monitored by spot-observation method. The density, plague four-step test Long-tailed organ of Chrysolophus and body-flea of Long-tailed Chrysomilax were used to detect the F1 antibody against serum of long-tailed Chlamys farrei and mare serum by indirect hemagglutination test. Results The density of Haemonchus koreanum in June-July was 10.25 / hm2 and 17.43 / hm2 respectively, the rate of flea infection was 88.9% and the average flea index was 6.3. The density of Haematopus xylostella from June to July was 0.23 / hm2 and 0.38 / hm2; Plague etiology monitoring 11 strains of Yersinia pestis were isolated from long-tailed hamsters and their body fleas, serological tests were performed on 354 serums from Long-tailed hamsters, 12 were positive for the F1 antibody against the plague and 17 were positive for the flocks, . Conclusions In 2012, the outbreak of plague epidemic in animals of the natural foci of Guttut area is very active and has the potential to affect human beings. Therefore, it is necessary to continue the effective plague surveillance.
