呼伦贝尔盟(呼盟)位于内蒙古自治区东北部,辖13个旗(市)有4个牧业旗,草原面积约9.2km~2,人口25.3万人, 饲养牛43.7万头,羊160.2万只。历史上曾有布氏菌病(布病)发生与流行,1956～1964年(高峰年)有新发患者2776名,慢性患者万余人,布病普查人间感染率平均为7.2％。曾因布病导致母牛、羊大批流产,流产率高达15.9％和7.8％,牛、羊布氏菌感染率高达19.5％和17.4％。经多年防治,80年代初期基本控制了流行,只限局部零散发生布病,连续5年未有新发患者,重点调查人感染率在1％以下,牛羊感染率为2.5％和1.14％。有1个旗经自治区验收已达到国家控制标准。但1988年后,又出现新发患者,特别是在1991年后,每年都有5个以上苏木(乡)有人、牛、羊的布病发生,至1995年已先后有21个苏木发生布病,其面积占45％,现将1991～1995年呼盟牧区布病疫情分析如下。
Hulun Buir League (Ho Meng League) is located in the northeast of Inner Mongolia Autonomous Region, jurisdiction over 13 flags (city) has 4 animal husbandry flags, grassland area of about 9.2km ~ 2, population 253,000 people, 437,000 cattle and sheep 1.660 million. Historically, brucellosis (brucellosis) had occurred and was prevalent. There were 2,776 new patients from 1956 to 1964 (peak year), and more than 10,000 were chronic patients. The average prevalence rate of brucellosis was 7.2%. As a result of brucellosis, a large number of cows and sheep were aborted with abortion rates as high as 15.9% and 7.8%, and brucellosis with cattle and sheep as high as 19.5% and 17.4% respectively. After years of prevention and control, the epidemic was basically controlled in the early 1980s. Only local sporadic cases of brucellosis were reported. No new cases were found in the past five consecutive years. Infection rates were below 1% for key investigators and 2.5% and 1.14% for cattle and sheep. A flag by the autonomous region has reached the state control standards acceptance. However, new patients appeared again after 1988, especially after 1991, more than five brums of cattle, sheep and sheep have occurred in each year and 21 hematomas have occurred in 1995 Cloth disease, the area of 45%, now 1991 ~ 1995 Hohhot pasture brucellosis epidemic analysis is as follows.
