An experiment was conducted to determine if cattle could be infected with a strain of Brucella abortus biovar 1 isolated from a bison in Wood Buffalo National Park. Three pregnant cows inoculated conjunctivally with 5.7 x 10(8) cfu of the bacterium, and their subsequent calves, showed seroconversion on standard serological tests for bovine brucellosis, and large numbers of the bacterium were isolated from numerous tissues at necropsy. A 4th cow that was moved into the pen that previously contained the inoculated cows subsequently showed seroconversion, and the same strain of B. abortus biovar 1 was isolated from numerous tissues. Although this strain from bison in Wood Buffalo National Park has existed in isolation from cattle for over 60 years, it remains infectious and contagious for cattle.
进行了一项实验，以确定牛是否会感染从伍德布法罗国家公园的一头野牛分离出的流产布鲁氏菌生物变种1菌株。三只怀孕母牛通过结膜接种5.7×10⁸ cfu的该细菌，其随后出生的小牛在牛布鲁氏菌病的标准血清学检测中出现血清转化，并且在尸检时从许多组织中分离出大量该细菌。第四头母牛被转移到先前装有接种母牛的围栏中，随后也出现血清转化，并且从许多组织中分离出相同的流产布鲁氏菌生物变种1菌株。尽管来自伍德布法罗国家公园野牛的这种菌株已经与牛隔离存在了60多年，但它对牛仍然具有传染性。
