A total of 191 cows in 3 herds were injected with a brucella protein antigen in an effort to compare serologic and bacteriologic findings with delayed hypersensitivity and to possibly detect incubative brucellosis. Using cultural and serologic results, the responses to the BPA antigen were inferior to serologic tests in the diagnosis of infection. None of the 23 skin test positive/seronegative cows were positive on subsequent herd blood tests.
为了比较血清学和细菌学检查结果与迟发型超敏反应，并有可能检测出潜伏性布鲁氏菌病，对3个牛群中的191头奶牛注射了布鲁氏菌蛋白抗原。根据培养和血清学结果，在感染诊断方面，对布鲁氏菌蛋白抗原的反应不如血清学检测。23头皮肤试验阳性/血清学阴性的奶牛在随后的牛群血液检测中均未呈阳性。
