During an investigation of bovine brucellosis in Iran, conducted by the Razi Institute over a twelve-month period, samples of serum and milk were collected simultaneously from 6,472 cows in eight infected herds for serological and bacteriological testing. A total of 1,056 cows were serologically positive and 1,632 of 6,472 milk samples were positive to the milk ring test (MRT). Culture of the positive milk samples yielded 397 isolates of Brucella, 119 of which came from the 5,686 seronegative cows. The isolates belonged to Brucella abortus biotypes 2 (one isolate), 3 (356 isolates) and 9 (40 isolates).
在拉齐研究所对伊朗牛布鲁氏菌病进行的为期十二个月的调查中，同时从八个受感染牛群的6472头奶牛采集血清和牛奶样本进行血清学和细菌学检测。共有1056头奶牛血清学呈阳性，6472份牛奶样本中有1632份乳环试验（MRT）呈阳性。对阳性牛奶样本进行培养，得到397株布鲁氏菌分离株，其中119株来自5686头血清阴性奶牛。这些分离株属于流产布鲁氏菌生物型2（1株分离株）、3（356株分离株）和9（40株分离株）。
