摘要/Abstract

摘要： 旨在了解新疆地区梅迪维斯纳病的流行现状和特点，本研究于2017—2019年从新疆阿克苏、阿勒泰、巴州、昌吉、哈密、石河子和伊宁收集2 647份羊血清样品，采用酶联免疫吸附试验（ELISA）进行梅迪维斯纳病抗体检测，对不同地区、品种、性别来源绵羊的梅迪维斯纳病抗体阳性率进行统计分析。结果显示，阿克苏、阿勒泰、巴州、昌吉、哈密、石河子和伊宁梅迪维斯纳病抗体阳性率分别为28.95%（121/418）、0.67%（5/751）、2.50%（2/80）、4.91%（8/163）、1.14%（3/264）、1.22%（1/82）和17.10%（152/889）；其中，阿勒泰羊、和田羊、哈萨克羊、美利奴羊、萨福克羊、小尾寒羊的梅迪维斯纳病抗体阳性率分别为0.35%（1/288）、1.14%（3/264）、22.87%（231/1 010）、13.86%（42/303）、1.85%（13/702）和2.50%（2/80）；新疆本土品种羊与引进品种羊血清梅迪维斯纳病抗体阳性率分别为0.79%（8/1 015）、1.58%（15/947）；公羊与母羊梅迪维斯纳病抗体阳性率分别为3.59%（34/946）、15.17%（258/1 701）。本研究结果分析表明，需要对梅迪维斯纳病进行早期检疫，及时发现并淘汰病羊，改善饲养管理条件，这对促进羊产业健康发展具有重要意义。

Abstract: To investigate the epidemic status and characteristics of Maedi-Visna disease in Xinjiang, this study collected 2 647 samples of sheep sera from Aksu, Aletai, Bazhou, Changji, Hami, Shihezi, Yining, from 2017 to 2019. Enzyme-linked immunosorbent assay (ELISA) was performed to detect Maedi-Visna antibody. Statistical analysis of the positive rate of sheep Maedi-Visna antibody in different varieties, genders and regions. The detection rate of Aksu, Altay, Bazhou, Changji, Hami, Shihezi and Yining were 28.95% (121/418), 0.67% (5/751), 2.50% (2/80), 4.91% (8/163), 1.14% (3/264), 1.22% (1/82) and 17.10% (152/889). The positive rate of Aletai sheep, Hetian sheep, Kazakh sheep, Merino sheep, Suffolk sheep and Small Tail Han sheep, were 0.35% (1/288), 1.14% (3/264), 22.87% (231/1 010), 13.86% (42/303), 1.85% (13/702) and 2.50% (2/80), respectively. The positive detection rate of local variety and introduced variety were 0.79% (8/1015), 1.58% (15/947), respectively. The positive detection rate of female and male were 3.59 % (34/946) and 15.17 % (258/1 701), respectively. These results indicated that it is necessary to carry out early quarantine of Meadi-Visna disease, identify and eliminate the sick sheep timely, and improve the feeding and management conditions, which is of great significance to promote the healthy development of the sheep industry.
