Published reports of Brucella abortus infections in wild North American ungulates and domestic cattle herds were reviewed to determine if infection in these species was related. Bison (Bison bison) were frequently found infected, but are probably a minor threat to livestock due to their current limited distribution. Most elk (Cervus elaphus) were free of infection except where their range was shared with infected bison or livestock. Deer (Odocoileus spp.), pronghorns (Antilocapra americana), moose (Alces alces), and bighorn sheep (Ovis canadensis) appeared to be insignificant hosts of Brucella abortus. The lack of significant wild ungulate hosts and the distribution of infected livestock herds in the United States suggests that wild ungulates are of little importance in the epidemiology of infections by B. abortus in cattle.
回顾了已发表的关于北美野生有蹄类动物和家养牛群感染布鲁氏菌流产亚种的报告，以确定这些物种的感染是否相关。经常发现野牛（美洲野牛）受到感染，但由于其目前分布有限，对家畜可能构成较小威胁。除了与受感染的野牛或家畜共享活动范围的地方外，大多数麋鹿（马鹿）没有感染。鹿（白尾鹿属）、叉角羚（叉角羚）、驼鹿（驼鹿）和大角羊（加拿大盘羊）似乎是布鲁氏菌流产亚种的不重要宿主。美国缺乏重要的野生有蹄类动物宿主以及受感染家畜群的分布表明，野生有蹄类动物在牛感染布鲁氏菌流产亚种的流行病学中不太重要。
