和于1949年曾提出布氏杆菌病存在自然疫源性的假说,因此开展了野外性及实验性的研究,试求解决这个问题。苏联微生物学和流行病学研究所及高加亲和南高加索科学研究所的同仁等最近二年作了3000只金花鼠和400只以上鼠型啮齿类的细菌学检查,这些动物是从羊布氏杆菌病疫源地捕捉的,布鲁氏菌分离培养未成功,对在布氏杆菌病地区居住的将近200只羚羊进行细菌学检查结果也是阴性。从流产的和生仔的母山羊母绵羊和其他家畜身上捕集了7150只壁蝨,接种到豚鼠身上分离出3株Br·meItIsie(0.04％)。1955年报告从各个羊布氏杆菌病疫源地收集6000只壁虱得到2株Br·meIitenie(0.05%),同样分离出0.06％。著者等在同样疫源地当 And the hypothesis that natural brucellosis was present in Brucella in 1949, a field and experimental study was conducted to try to solve the problem. The bacteriological examination of 3000 rodents and more than 400 rodents in the last two years was conducted by the Soviet Institute of Microbiology and Epidemiology and colleagues at the Gajah Affinity and South Caucasus Institute of Science. These animals are from the sheep Brucellosis was not successfully isolated from the source of brucellosis. Bacteriological examination of nearly 200 antelopes living in areas with brucellosis was also negative. Seventy-one and a half hundred ticks were collected from aborted and infested mother-goat and other domestic animals and inoculated into guinea pigs and three Br. MeItIsie (0.04%) were isolated. In 1955, 2 Br Meitenie (0.05%) were collected from 6,000 ticks of each brucellosis originating in sheep and 0.06% were also isolated. Author and so on in the same foci
